EM BUSCA DE COERÊNCIA ENTRE O DIZER E O FAZER NA FORMAÇÃO DE PROFESSORES DO MESTRADO PROFISSIONAL EM LETRAS
Authors: Sartori Adriane Teresinha
Published: February 2019

Resumo: Este trabalho analisa uma experiência de produção de um artigo acadêmico na disciplina Ensino da Escrita, Didatização e Avaliação, desenvolvida no Profletras/UFMG, em 2017. Ancorados em abordagens qualitativo-interpretativista de pesquisa, os resultados apontam para o fato de que o confronto entre se assumir autor de um artigo e ser professor de discentes produtores de textos pode propiciar um dinâmico movimento de reflexões sobre todas as etapas do processo. No papel de professor de professores, o desafio de construir coerência entre o que se diz e o que se faz revela inúmeras concepções, também relacionadas à formação profissional docente.
A LEITURA EM UM CONTEXTO DE ENSINO DE LÍNGUA PORTUGUESA: UM CONVITE À REFLEXÃO
Authors: Correia Letícia Veste , Bedran Patrícia Fabiana
Published: February 2019

O objetivo desta pesquisa é investigar as crenças acerca da leitura e das atividades de leitura em aulas de língua portuguesa, apresentadas por uma professora de uma escola da rede pública do ensino fundamental I, bem como promover uma discussão sobre os procedimentos do professor no que diz respeito ao trabalho com a leitura e as suas implicações para o processo de formação dos alunos. Trata-se de uma pesquisa qualitativa, de cunho etnográfico (ERICKSON, 1986; ANDRÉ, 2000), que apresenta como referencial teórico as pesquisas sobre crenças (BARCELOS, 2006; SILVA 2007), leitura e ensino (SOLÉ, 1998; KLEIMAN, 2001; SAVELI, 2003; SOARES, 2004) e formação reflexiva do professor (PIMENTA; GHEDIN, 2002 e ZEICHNER, 2008).
O DESENVOLVIMENTO DE HABILIDADES LEITORAS A PARTIR DO GÊNERO MULTIMODAL TIRINHA
Authors: Santos de Souza Maria Genilda , Souto Sales Laurênia
Published: February 2019

Tornar-se proficiente na linguagem multimodal é essencial para que os alunos compreendam os vários gêneros que circulam socialmente. Assim, o trabalho com tirinhas pode ser considerado um caminho para o desenvolvimento de habilidades leitoras. O estudo pauta-se em Koch e Elias (2013) e Solé (1998), sobre leitura; Dionísio (2011), sobre multimodalidade e letramentos; Vergueiro (2014) e Ramos (2016), sobre quadrinhos. Trata-se de uma pesquisa-ação de caráter intervencionista, na qual foram realizadas oficinas de leitura. Como resultados, os alunos consolidaram habilidades leitoras já adquiridas e avançaram em outras, como inferir informação implícita e interpretar texto com auxílio de material gráfico diverso.
ANÁLISE COMPARATIVA ENTRE OS TEXTOS LITERÁRIOS “A RESISTÍVEL ASCENSÃO DE ARTURO UI”, DE BERTOLD BRECHT (1941) E “A RESISTÍVEL ASCENSÃO DO BOTO TUCUXI”, DE MÁRCIO SOUZA (1982)
Authors: Da Silva Jocilene D Avila , Silva Verônica Diniz da , Ribeiro João Carlos de Souza
Published: February 2019

No plano conteudístico, o presente trabalho - análise comparativa - tentará mostraromo a narratividade do texto de Márcio Souza, A resistível ascensão do Boto Tucuxi, faz uso da obra de Bertolt Brecht, A resistível ascensão de Arturo Ui, e se apropria do título e dos principais elementos da trama para fazer uma leitura do comportamento político populista amazonense. A obra de Márcio Souza, portanto, liga-se à de Brecht pela veia da política e da ideologia em que ambos realizam uma mordaz crítica aos interesses dominantes na sociedade; tratam-se de paródias que transmitem a forma pela qual o povo percebe e compreende  os donos do poder.

Assim, partindo das observações feitas, buscou-se, na proposta da dissertação, a constituição de ações que pudessem amenizar os problemas da realidade observada.
O TEXTO LITERÁRIO EM LIVROS DIDÁTICOS DE LÍNGUA PORTUGUESA DO ENSINO FUNDAMENTAL II:
Authors: Cocco Marta Helena , Baggenstoss Deise
Published: February 2019

Neste artigo, apresentamos resultados de uma pesquisa sobre abordagem do texto literário em alguns livros do PNDL, bem como a presença ou ausência do texto literário produzido em contexto regional, especificamente em Mato Grosso. A partir dos resultados obtidos, constatamos a quase ausência de textos de autores regionais e, assim, defendendo a sua necessária presença, propusemos um programa de leituras como alternativa para tal lacuna. Nossos apontamentos foram subsidiados por orientações dos PCN, pela concepção de letramento literário de Cosson (2012) e de leitura cursiva e analítica de Rouxiel (2012, 2013a), além de considerações sobre a importância do ensino da literatura regional.

Published: February 2019

A Avaliação da Aprendizagem em Processo (AAP) é um coeficiente adotado pela Secretaria da Educação do Estado de São Paulo (SEESP), desde 2011, como forma de analisar o aprendizado de estudantes do ciclo fundamental II e médio com relação à aprendizagem de Língua Portuguesa (LP). Basearemos nossas discussões em SOLÉ (1998), MARCUSCHI (2010), DIONÍSIO; VASCONCELOS (2013) e de outros textos científicos produzidos por PRADO; GARCIA (2017). Trata-se de aumentar a visibilidade e transparência a um método avaliativo de língua materna, o qual já atingiu um status de institucionalizado dentro do maior Estado do país e carece de observações.
PERCY JACKSON E O LADRÃO DE RAIOS: PROPOSTA DE ATIVIDADE DE MULTILETRAMENTO E DE DIALOGISMO
Authors: Teodoro Thelma Maria Figueira , Almeida Maria do Carmo Souza de
Published: February 2019

Alguns gêneros discursivos exigem leitura verbo-visual, gerando a necessidade de multiletramento; também é preciso considerar que os discursos formam uma cadeia discursiva. Assim, objetiva-se relatar uma atividade de análise do filme “Percy Jackson e o ladrão de raios”, desenvolvida no Ensino Fundamental I. Multiletramento, letramento multimidiático e dialogismo fundamentam o trabalho. Durante a exibição do filme, buscou-se relacionar as histórias de Hércules e de Perseu, além de comparar as figuras mitológicas das obras estudadas. Os resultados indicam semelhanças e diferenças entre as histórias e as personagens, uso de múltiplas linguagens e diálogo entre as histórias dos heróis.

Authors: Rita de Jesus Cruz Vanessa
Published: February 2019

Esse texto tem como objetivo realizar uma breve análise da obra Odisseia de Homero (segundo João Vítor), de Gustavo Piqueira, publicada em 2013. Para tanto, abordaremos algumas questões referentes à Literatura e o seu ensino, à formação do leitor e à Semiótica, que “se trata de uma das teorias voltadas para a investigação a respeito do modo como os sujeitos produzem sentidos para os textos e, portanto, tem implicações para uma didática da leitura” (SILVA, 2017, p. 196). Ressaltamos, também, o papel essencial que o professor desempenha no processo de aproximar o leitor do texto literário.

Published: February 2019

Este artigo apresenta a análise de produções textuais de alunos do ensino fundamental, a partir da aplicação de sequência didática (SD) (DOLZ, NOVERRAZ, SHENEUWLY, 2004) para o ensino do gênero resenha crítica. Como arcabouço teórico, recorremos à perspectiva de gênero discursivo de Bakhtin (2003) e de Biasi-Rodrigues (2008), em seguida, abordamos o gênero resenha crítica, por meio de Medeiros (2014) e Machado, Lousada & Abreu-Tardelli (2014). Por fim, concluímos que, com o uso de SD, é possível que os alunos do ensino fundamental tornem-se bons escritores de textos e se apropriem dos mais diversos gêneros discursivos.
PESQUISA OU DESENVOLVIMENTO PROFISSIONAL DE PROFESSORES NO MESTRADO PROFISSIONAL EM LETRAS?
Authors: Dos Santos Marcos Bispo
Published: February 2019

Neste artigo, questionam-se dois pressupostos ligados à compreensão do trabalho de conclusão final e aos objetivos do Mestrado Profissional em Letras (Profletras). O primeiro deles refere-se às possibilidades de certa concepção de a pesquisa aplicada constituir o meio adequado para a consecução dos objetivos dessa modalidade de pós-graduação. O segundo, que expressa certo consenso vigente no contexto acadêmico, consiste no entendimento de que seu objetivo precípuo seria formar o chamado professor pesquisador. Na metodologia, confrontam-se os dados da pesquisa documental, a partir da qual foram identificados os aspectos legais relativos aos Mestrados Profissionais (MP) e ao Profletras, com os dados da pesquisa bibliográfica, por meio da qual foram mapeados os principais modelos de formação de professores. Concluiu-se que a perspectiva técnica, modelo de formação ao qual se ligam a concepção de pesquisa aplicada que orienta as bases legais dos MP e a concepção de professor-pesquisador, apresenta limitações intransponíveis diante do objetivo de promover o desenvolvimento profissional de professores de língua portuguesa, como se propõe o Profletras.
Non-Synaptic Transmission and the Foundations of Affect
Authors: Carvalho Gil , Damasio Antonio
Published: February 2019

Neuroscience has overwhelmingly and understandably focused on the synaptic modality of signal transmission. There is evidence, however, that from an evolutionary perspective, non-synaptic transmission (NST) preceded synaptic signaling. Moreover, in modern nervous systems, NST coexists and extensively interacts with synaptic transmission modifying neuronal dynamics. In fact, NST remains widespread in complex animals, especially within the interoceptive system where the dearth of insulating barriers such as myelin sheaths and the blood-brain barrier enhances the communication between neural and non-neural tissues mediated by NST. We suggest that this physiological arrangement makes a fundamental contribution to interoception¾the process of sensing visceral states¾which is an essential underpinning of the capacity to feel and the foundation of affective processing.
Adherencia y resultados. Un análisis de componentes estratégicos en salud mental escolar
Authors: Rojas-Andrade Rodrigo , Leiva Bahamondes Loreto
Published: February 2019

La adherencia es una de las variables más estudiadas de la fidelidad de la implementación en salud mental escolar, pero son pocos los estudios que la abordan considerando los componentes estratégicos de intervención. Objetivo. El propósito de esta investigación fue indagar si los patrones de adherencia a componentes estratégicos influyen sobre los resultados del programa chileno Habilidades para la Vida. Metodología. Se tomaron datos de 110 comunas del país. Se aplicó el Cuestionario de Evaluación de la Calidad de Programas de Salud Mental Escolar a coordinadores de equipos de implementación y se creó un índice comunal de mejoramiento socioemocional basado en las respuestas de padres y profesores a la encuesta de evaluación anual del programa. Resultados. Se identificaron 19 componentes que se asocian a estrategias de intervención, diseño y evaluación, trabajo colaborativo y aprendizaje del modelo del Programa. Con estos se calcularon modelos de clases latentes, encontrando dos patrones de adherencia. A través de un ANOVA se evidenció que los equipos que desarrollan un patrón adherente obtienen resultados significativamente mayores que los que desarrollan un patrón no adherente. Discusión. Se concluye que los resultados del programa son mejores cuando los equipos son adherentes a ciertos componentes estratégicos definidos como esenciales. Se discuten las implicancias prácticas de este hallazgo.
Silver Thiosulfate Prevents Ethylene-induced Abscission in Holly and Mistletoe
Authors: Joyce Daryl C. , Reid Michael S. , Evans Richard Y.
Published: February 2019

Low concentrations of ethylene induced abscission of leaves and berries from cut branchlets of English holly (Ilex aquifolium L.) and American mistletoe [Phoradendron tomentosum (DC.) Engelm. ex Gray ssp. macrophyllum (Engelm.) Wiens]. Application of 1 μmol of Ag+ per branchlet (as the anionic silver thiosulfate complex, STS) via the transpiration stream was found to retard this abscission. A higher application rate (4 μmol Ag+ per branchlet) stimulated leaf abscission in mistletoe. There were marked differences in sensitivity to ethylene among various types of holly.
Organoleptic Evaluation of Shrink-wrapped Muskmelon
Authors: Collins J.K. , Bruton B.D. , Perkins-Veazie P.
Published: February 2019

Organoleptic evaluations of shrink film-wrapped and nonwrapped musk-melon (Cucumis melo L. var. reticulates cv.. TAM Uvalde) fruit were conducted to determine changes in flavor and taste during refrigerated storage. Ripe green and yellow `TAM Uvalde' muskmelons, shrink film-wrapped in 12.7-μm high-density polyethylene film, were compared to nonwrapped melons during 21 days of storage at 4C and 90% to 95% RH. After 21 days of storage, both yellow and green shrink-wrapped melons had better appearance, less surface mold, and less vein tract browning than nonwrapped melons. However, the flavor and taste of shrink-wrapped fruit were significantly inferior to those of nonwrapped melons. Green-wrapped melons were rated poorer in taste and flavor than yellow-wrapped and nonwrapped melons after 14 days of storage. These results indicate that shrink-wrapping may enhance undesirable flavor changes in muskmelon during storage.
Vitrification of Crabapple, Pear, and Geum on Gellan Gum-solidified Culture Medium
Authors: Turner Steven R. , Singha Suman
Published: February 2019

Shoots of `Almey' crabapple [Malus baccata (L.) Borkh. × M. pumila var. niedzwetzkyana (Dieck) Schneid.], `Seckel' pear (Pyrus communis L.), and `Mrs. Bradshaw' geum (Geum quellyon Sweet.) were cultured on Murashige and Skoog (MS) medium supplemented with 8.8 μm BA and containing 0.1% to 0.4% Gelrite. Comparative shoot proliferation and vitrification were determined on Phytagar-solidified medium. Shoot proliferation, culture fresh weight, and vitrification declined in crabapple and geum with increasing Gelrite concentration. Pear proliferation and fresh weight increased with increasing Gelrite levels, but all shoots were vitrified. There were differences in the vitrification response between pear and the other two genera. The percent dry weight of vitrified cultures on Gelrite-containing media was generally higher than that of nonvitrified cultures on medium containing Phytagar. Vitrification precludes using low Gelrite concentrations for propagating these plants. Chemical name used: N-(phenylmethyl) -1H-purin-6-amine (BA).
MINILEE AND MICKYLEE: HIGH QUALITY ICEBOX WATERMELON CULTIVARS FOR U.S. AND FOREIGN MARKTETS
Authors: Elmstrom G. W. , Crall J. M. , Maynardr D. N.
Published: February 2019

Icebox watermelons have been available for some time, but have never attained commercial importance in the United States. In trials at Bradenton, Leesburg, and Live Oak, FL `Minilee' and `Mickylee' (mean weights of 7.5 and 10.0 pounds, respectively) matured earlier than other cultivars and produced yields equal to or better than other icebox cultivars. They had better internal quality and a higher level of resistance to Fusarium wilt than other available icebox cultivars. In storage tests `Minilee' was less susceptible to chilling injury than `Mickylee', `Sugar Baby', or `Baby Fun'; the flesh of `Mickylee' and `Minilee' was firmer and retained firmness better during storage than did the other two icebox cultivars. Icebox melons have appeal to individual home consumers and are well suited for shipment in cartons to both domestic and foreign markets.
SYMPTOM DEVELOPMENT AND TISSUE CONCENTRATIONS OF CHLORIDE AND BORON TOXICITY IN KIWIFRUIT
Authors: Hasey Janine , Uriu K. , Pearson J.
Published: February 2019

Chloride and boron toxicity symptoms and tissue concentrations were characterized and distinguished in kiwifruit. Dormant cane, bud, emerging leaves, blade and petiole samples were taken from February through October 1989 from three vineyards - a high chloride, a high boron and a low boron, low chloride control. Chloride toxicity symptoms started showing in early summer on basal leaves. By late summer, necrosis symptoms were on mid-shoot and leaves near the shoot terminal. In boron toxicity, interveinal chlorotic areas appeared first followed by marginal necrosis. Symptoms were seen on basal leaves in early spring, progressively affecting upper leaves by harvest. The high chloride vineyard accumulated chloride from early spring with the petiole concentrating more chloride than the blade. In the high boron vineyard, boron increased greatly in the blade but not in the petiole. Another sampling procedure other than mid-season leaf samples could be emerging leaves for detecting high chloride and dormant cane tips, buds or emerging leaves for high boron.
THE EFFECT OF DEFOLIATION ON STRAWBERRY FRUITING RESPONSE
Authors: Albregts E. E. , Howard C. M. , Chandler C. K.
Published: February 2019

During 2 seasons, defoliated and non-defoliated strawberry plants were evaluated for their fruiting response using the annual hill cultural system in Dover, FL. Partially dormant Canadian grown `Chandler' and non-dormant locally grown FL breeding line 79-1126 were grown the first season. Locally grown `Dover' was added the second season. Total yields of all clones were reduced with foliage removed. Monthly yields were reduced the first season with FL 79-1126 defoliated plants, but only the April yield of defoliated `Chandler' was reduced. December, January, March, and total yields of defoliated plants from all clones were reduced the second season. Average seasonal fruit weight was reduced the second season with locally grown defoliated plants. During the second season the percent marketable fruit of `Chandler' and FL 79-1126 was greater with the defoliated plants.
INFLUENCE OF PLANTING DATE AND HARVEST TIME ON ARTEMISIA ANNUA L.
Authors: Cebert Ernst , Charles Denys J. , Simon James E.
Published: February 2019

Artemisia annua L. is an aromatic and medicinal plant of importance for its volatile essential oils, and the non-volatile artemisinin used in the treatment of malaria. To determine the optimum time of planting for growth and the accumulation of essential oils, seedlings of A. annua (Purdue accession 012) were transplanted into the field in Central Indiana in a RBD with 3 replications on April 25, May 24, June 24, and July 25, 1988. Plant samples were harvested every 2 weeks until first frost.

The April and May transplanting dates produced the tallest plants (>180 cm) while the May transplants accumulated the greatest fresh and dry weights. The average increase in plant height was greatest for the June 24 planting date at 9.8 cm per week. Regardless of planting date, all plants began to flower by early August and growth rate began to decrease by late August. Accumulation of essential oil (as rel. % dry wt.) was similar for all planting dates. Essential oil increased until floral initiation, then decreased for 2 weeks after which there was a rapid increase in oil accumulation. Maximum oil accumulation from all planting dates was reached on Sept. 28 after which growth continued to increase.
Frost/Freeze Protection of Strawberries Grown on Black Plastic Mulch
Authors: Poling E.B. , Fuller H. Pat , Perry K.B.
Published: February 2019

Floating rowcovers composed of extruded polypropylene, spunbonded polypropylene, and polyester were used in 1987-88 in eastern North Carolina for cold protection of strawberries (Fragaria × ananassa Duch.) growing in annual hill culture on black plastic mulch. Treatments consisted of floating rowcovers in either winter, spring, or both with and without overhead irrigation for spring frost/freeze protection, in addition to irrigated and nonirrigated unprotected plots. Winter rowcovers increased air temperatures by 1 to 2C without advancing bloom or harvest date. Significant blossom temperature differences relative to rowcover materials (≈ 1.5C) and irrigation use (≈ 1.5 to 3.0C) were detected over the course of six spring frosts. Time of application of covers (winter or spring) and irrigation in spring interacted in their effects on early yields (25 Apr.-5 May). However, rowcover and irrigation treatments did not have a significant effect on total marketable yield, yield per plant, or berry mass. In the absence of higher prices for early than late-season fruit or of more severe environmental extremes than experienced in the current study, it would be difficult to justify the added expense of rowcovers.
Condition of Florida Grapefruit after Exposure to Vapor Heat Quarantine Treatment
Authors: Miller W.R. , McDonald R.E. , Hallman G. , Sharp J.L.
Published: February 2019

Experimental vapor heat (VH) tests [43.5C for 5 hours, 1009” relative humidity (RH)] were conducted to determine treatment effects to freshly harvested Florida grapefruit (Citrus paradisi Macf.). VH treatment reduced peel pitting 5-fold compared to control fruit after 5 weeks of storage (4 weeks at 10C + 1 week at 21C) and did not cause peel discoloration or rind breakdown. There was no difference in volume between treated and nontreated fruit after 1 week of storage or in weight loss after 5 weeks. Also, peel color, total soluble solids concentration, acidity, and pH were not affected by VH treatment. Fruit were slightly less firm after VH treatment and remained less firm throughout storage, compared with control fruit. The VH treatment tested is a potentially viable alternative quarantine treatment for control of the Caribbean fruit fly [Anastrepha suspensa (Loew)] because it is not phytotoxic to grapefruit and has been reported effective for disinfestation of this pest in grapefruit.
Rootstock Affects Primary Scaffold Branch Crotch Angle of Apple Trees
Authors: Warner John
Published: February 2019

`Sturdeespur Delicious', `MacSpur`, `Summerland McIntosh', `Idared', and `Empire' apple trees (Malus domestics Borkh.) planted in 1986 on various size-controlling rootstock were used to determine the effect of rootstock on primary scaffold branch crotch angle. There were differences in crotch angle depending on rootstock. Rootstock effects were more pronounced with the upright growing `Sturdeespur Delicious' than with `Idared' and `Empire', which have a spreading growth habit. Ottawa 8 rootstock had a tendency to produce primary branches with wider crotch angles than other semidwarf to standard rootstock.
Relationships between Shoot Productivity and Leaf Characteristics in Peach Canopies
Authors: DeJong T.M. , Day K.R.
Published: February 2019

The relationships between shoot light exposure in one year and the flower and fruit production characteristics of those shoots the following year were indirectly investigated in summer pruned and nonsummer pruned peach [Prunus persica (L.) Batsch.] trees by evaluating leaf characteristics (leaf N and dry matter content per unit leaf area; Na and Wa, respectively) on tagged shoots during one season and the flowering and fruiting characteristics during the subsequent season. There were significant positive linear relationships between leaf Na and Wa on shoots in one year and flower and fruit production per unit shoot length during the subsequent year. Summer pruning had relatively little influence on these relationships. There was no apparent relationship between percent fruit set in the spring and light exposure of the shoots the previous summer. Following dormant pruning and commercial thinning, trees summer-pruned the previous year had higher yields than nonsummer pruned trees because of less shoot mortality and more fruit per tree.
Physiological and Quality Response of Guava Fruits to Posture during Storage
Authors: Siddiqui S. , Sharma R.K. , Gupta O.P.
Published: February 2019

Fruits from the winter season crop of guava (Psidlum guajava L.) were harvested at the green mature stage and stored at ambient conditions in three postures: 1) natural, pedicel end vertically upward; 2) reverse, pedicel end vertically downward; and 3) horizontal, pedicel end sideways. Fruits in the natural posture showed minimum physiological loss in weight, ripening percentage, ethylene and CO2 evolution rates, and maximum soluble solids and ascorbic acid concentrations during storage. Organoleptic rating and other characteristics indicate that guava fruits should be packed in the natural posture to retain better quality for longer periods.
A Novel Lace-leafed Pecan
Authors: Marquard Robert D.
Published: February 2019

More than 30 pecan [Carya illinoensis (Wangenh.) K. Koch] seedlings of `Riverside' have exhibited an unusual leaf morphology described as lace-leafed. Seedlings have relatively low vigor, compound leaves, and leaflets with deeply serrated margins with higher length: width ratios than normal seedings. Some leaves are both pinnate and palmately compound and some leaflets are lobed. The segregation ratio of lace-leafed seedlings for one gene controlling a polymorphic genetic marker supports the hypothesis that lace-leafed seedlings result from selfing of `Riverside.' Nine percent (three of 33) of seedlings derived from selfing of `Riverside' exhibited the lace-leafed morphology, suggesting a recessive trait controlled by one or two genes. The gene(s) controlling this phenotype in pecan is arbitrarily designated the ll gene(s).

Authors: Strik Bernadine C. , Roper Teryl R. , DeMoranville Carolyn J. , Davenport Joan R. , Poole Arthur P.
Published: February 2019

This research was undertaken to document the extent of biennial bearing in flowering uprights by American cranberry (Vaccinium macrocarpon Ait) cultivar and growing region. Seven cultivars were studied: three found in all states considered (Massachusetts, New Jersey, Wisconsin, Oregon), two common to Massachusetts and New Jersey, and two other commercially grown cultivars, one each from Wisconsin and Oregon. There were significant cultivar, region, and cultivar × region interaction effects for both percent return bloom (%RB) and percent return fruit (%RF). Percent RB ranged from 74% for `Ben Lear' in Wisconsin to 14% for `Howes' in New Jersey. `Ben Lear' differed the most in %RB among regions, from 74% in Wisconsin to 14% in Massachusetts. However, in some regions, especially in Wisconsin, many blossoms did not set viable fruit. There was no significant difference in %RB among cultivars grown in Massachusetts or Oregon; however, cultivars grown in these regions did differ in %RF.
Interaction of Management Factors on Dollar Spot Disease Severity in Tall Fescue Turf
Authors: Brede A.D.
Published: February 2019

A field study was conducted to evaluate the effect of tall fescue (Festuca arundinacea Schreb.) cultivar, seeding rate, N fertilization rate, and cutting height on the severity of dollar spot (Lanzia and Moellerodiscus spp.) disease incidence. All possible two-factor interactions among these four management factors were statistically significant when averaged over the 2 years of study. Disease severity tended to be lowest at low fescue seeding rate (2100 pure-live seeds/m*) at the lower (19 mm) height of cut. `Mustang', the turf-type cultivar with improved density, was more susceptible to dollar spot than `Kentucky-31', the common-type cultivar.
Simulated Transport, Postproduction Irradiance Influence Postproduction Performance of Potted Roses
Authors: Nell Terril A. , Noordegraaf Cor Vonk
Published: February 2019

Three simulated transport temperatures (5, 11, or 17C) and durations. (3, 6, or 9 days) were used to evaluate the postproduction flowering patterns of miniature potted rose (Rosa sp) `Orange Rosamini'. The postproduction environment was maintained at 20 ± lC, 60% ± 5% relative humidity (RI-I), and an irradiance level, from cool-white fluorescent lamps, of 4.5 W·m-2 photosynthetically active radiation (PAR) for 12 hours daily to simulate conditions at the retail or consumer level. At 3 weeks postproduction, plants held for 9 days at 17C had the fewest buds showing color per plant. As temperature increased, there were fewer flowers per plant at weeks 2 and 3 of postproduction. In a second study, the effect of simulated transport (3 days at 5C vs. no transport) and postproduction irradiance level (1, 2, or 4 W·m-2 PAR) were evaluated over a 7-week postproduction period for `Orange Rosamini'. A three-way interaction was observed between simulated transport treatment, postproduction irradiance level, and time in postproduction for the number of open flowers per plant. Plants responded similarly at 1 and 2 W·m2 throughout the postproduction period, regardless of transport treatment; however, at 4 W·m-2 the plants of the no transport treatment had two to three open flowers each week up to week 6 of postproduction, while plants subjected to simulated transport followed the pattern of one and two open flowers for 0 to 3 weeks. Flowering then increased to three to four open flowers for the duration of the postproduction period. A third study involved two simulated transport treatments (3 days at SC vs. no transport), three postproduction irradiance levels (1, 2, and 4 W·m-2 PAR), and six miniature rose cultivars (`Orange Rosamini', `Red Minimo' `Sweet Rosamini', `Golden Rosamini', `Favorite Rosamini', and `White Rosamini'). Plants held at 1 or 2 W·m-2 for 3 weeks had no open flowers, while those held at 4 W·m-2 for 3 weeks had one to four open flowers, except `Sweet Rosamini', which had no open flowers with simulated transport.
Diurnal Pattern of Carbohydrates in Celery Leaves of Various Ages
Authors: Davis Jeanine M. , Loescher Wayne H.
Published: February 2019

Diurnal fluctuations in soluble carbohydrates and starch were monitored in young (expanding), mature (first fully expanded), and old (nearing senescence) celery (Apium graveolens L.) leaves. In all tissues, mannitol and sucrose were the carbohydrates present in the highest concentrations. In old and young leaflets and their petioles, there was little change in levels of mannitol and sucrose in 26 hours. In mature leaflets, sucrose accumulated in the light and decreased in the dark; mannitol increased slightly in late afternoon. Starch concentration, although quite low, showed definite diurnal fluctuations in mature leaflets, but only small changes in young and old leaflets. Both sucrose and mannitol were present in mature petiole phloem tissues. Mannitol concentrations were high in the adjacent storage parenchyma tissue, but sucrose was almost undetectable. These data support earlier findings that sucrose is produced, translocated, and metabolized throughout the celery plant. Mannitol is also translocated, but also serves as a major storage carbohydrate in leaf tissues, especially petiole parenchyma. Starch serves as a minor short-term storage compound in leaflets.
Contribution of Root and Shoot Tissues of Phaseolus vulgaris to Meloidogyne incognita Resistance
Authors: Mullin B.A. , Abawi G.S. , Pastor-Corrales M.A. , Kornegay J.L.
Published: February 2019

A stem grafting technique was used to determine the contribution of root and shoot tissues of bean (Phaseolus vulgaris L.) to the resistance response to the root-knot nematode, Meloidogyne incognita (Kofoid and White, 1919) Chitwood 1949. Stemgrafts were prepared between resistant (line A 211 or cultivar Nemasnap) and susceptible (Canario Divex) bean cultivars in all possible scion-rootstock combinations. Graft combinations in which the rootstock was resistant resulted in a resistant response to M. incognita, and those combinations in which the rootstock was susceptible resulted in a susceptible response, regardless of scion component. Resistance factors were therefore either localized within roots or not translocated basipetally through the stem graft union.

Authors: Knight R.J.
Published: February 2019

When Passiflora incarnata L. was crossed with P. edulis f. flavicarpa Degener, all plants of the diploid hybrid were pollen-sterile and nonfruitful. Doubling the chromosome number of emergent FI seedlings with colchicine restored fertility in some individuals, but all plants were strongly self-incompatible and many showed low pollen viability. Crossing colchicine-treated plants that had been converted to amphiploids produced a tetraploid hybrid group of four seedling progenies that had some degrees of cross-compatibility. Juice of the amphiploid hybrid is lighter in color than that of P. edulis, but is sweet, strongly aromatic, and may have use alone or, typically, as a blend with other juices.

Published: February 2019

Preplant-incorporated, preemergence, and postemergence herbicides were evaluated for yellow nutsedge (Cyperus esculentus L.) control and for phytotoxicity to four container-grown woody plants. Preplant-incorporated or preemergence applications of chlorimuron at 0.07 kg a.i./ha or imazaquin at 1.12 kg a.i./ha provided the greatest control of yellow nutsedge. Imazaquin applied at 0.28, 0.56, 0.84, or 1.12 kg a.i./ha suppressed growth of Rhododendron × `Copperman' azalea and Lagerstroemia indica ×sfauriai `Natchez'. All other herbicides tested were safe on the four woody plants evaluated. Chlorimuron provided the best combination of yellow nutsedge control and tolerance on woody ornamental. Chemical names used: 2-[[[[(4-chloro-6-methoxy-2-pyrimidinyl)amino]carbonyl]amino]sulfonyl]benzoic acid (chlorimuron); 2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-3-quinolinecarboxylic acid (imazaquin).

Authors: Moore Patrick P. , Robbins Jo Ann , Sjulin Thomas M.
Published: February 2019

The field performance of micropropagated and runner-propagated subclones of `Olympus' strawberry (Fragaria × ananassa Duch.) was compared. The yield of micropropagated plants was not greater than that of runner-propagated plants. There was significant variability among micropropagated subclones, with the highest yielding subclone having 68% higher yield than the lowest yielding subclone in each of the first 2 years. However, after runner propagation for 4 years, selected subclones showed no differences in yield. Differences among subclones of `Olympus' were not stable and were most likely transient responses to the micropropagation environment. The apparent superiority of the subclones was not genetic.
ALTERNATIVE METHODS FOR APPLYING ZINC TO APPLE TREES
Authors: Stiles Warren C.
Published: February 2019

Zinc deficiency is prevalent in apple orchards throughout the Northeast. Zinc contained in various fungicides is partially effective in meeting zinc requirements of apple trees.

Foliar application of EDTA-zinc chelates in two or more post-bloom cover sprays are effective in supplying zinc under most conditions. Alternative materials for such applications are also being studied.

Post-harvest or pre-bloom plus post-harvest applications of alternative sources of zinc did not produce consistent improvement of growth, yield, fruit size or color, or subsequent season zinc levels in leaf samples. Application of chelated zinc through trickle irrigation systems has provided significant improvements in leaf-zinc levels and is considered to be an effective means of supplying this element.
INHERITANCE OF TOLERANCE TO MINERAL ELEMENT INDUCED CHLOROSIS IN RABBITEYE BLUEBERRY
Authors: Gupton Creighton L. , Spiers James M.
Published: February 2019

A study was conducted to estimate heritability of the content of Mn, Fe, and certain other mineral elements which have been associated with leaf chlorosis and to determine the genetic relationships among shoot dry weight, visual rating, and the mineral elements in rabbiteye blueberry (Vaccinium ashei Reade). Plants from a 10-parent dialled set of crosses were grown in sand culture to which 200 ml of 250 ppm Mn solution were applied five days per week. Visual ratings (1 – dead plant - 13 – no toxicity symptom) were made after six weeks and shoot weight and mineral element contents were determined after 10 weeks of treatment. Heritability estimates were high for all variables except Fe, suggesting that change in Mn, Zn, Ca, Mg, or K content could be expected from phenotypic recurrent selection. However, manipulation of mineral content probably would not ameliorate the Fe chlorosis. The high heritability of shoot dry weight and visual rating and the high genetic correlation between the two variables suggest that plants resistant to mineral effects on Fe metabolism can be selected on the basis of visual rating.
MONITORING AS AN ESSENTIAL TOOL FOR FERTIGATION MANAGEMENT
Authors: Creech David L.
Published: February 2019

Blueberry growers are encouraged to monitor soil, leaf tissue, and irrigation water on a regular basis. Recommendations are based on soil, leaf, and water guidelines established from previous studies. A 1986-1988 blueberry field study in east Texas and Louisiana revealed the following significant associations with low vigor fields: 1) high soil pH, Ca, Mg and low Zn, 2) high leaf Na and B, and 3) high irrigation water conductivity and bicarbonates. The findings will be compared to other benchmark studies. pH, conductivity, and nutrient monitoring procedures of a large east Texas rabbiteye blueberry field are described. Careful record-keeping allows blueberry growers to fine-tune fertigation performance by altering nitrogen source and rate depending on changes in soil pH and conductivity.
EFFECT OF AGE OF TRANSPLANTS, PLASTIC MULCH AND ROW COVER ON OKRA YIELD.
Authors: Khan V. A. , Stevens C. , Lu J. Y. , Kabwe M. , Haung Z.
Published: February 2019

Clear (CM) and black (BM) plastic mulch and bare soil (BS) plus VisPore (V) row cover (VCM, VBM, VBS), BM, CM and BS in combination with drip irrigation were used to evaluate the growth response of these treatment combinations on 5 and 9 wks old `Clemson Spineless' okra transplants grown in sandy loam soil. Mulched treatments significantly increased the survival rate of 5 wks old transplants while VCM and VBM treatments increased significantly the number of vegetative branches of 5 wks over 9 wks old transplants. Total and marketable yield, as well as total and marketable number of pods were significantly influenced by mulched treatments rather than by the age of transplants.
BEE-SCENT FOR IMPROVED POLLINATION OF WATERMELON
Authors: Elmstrom G. W. , Maynard D. N.
Published: February 2019

Watermelon, Citrullus lanatus (Thunb.) Matsum. & Nakai, requires insects, most commonly honey bees, for pollination and fruit set. The transfer of an adequate amount of pollen is essential to ensure optimum fruit set, size, and shape. To encourage bee visits and the transfer of pollen, two applications of Bee-Scent*, a bee attractant, at 2.47 liter·ha-1 were made to watermelon on five farms in central and southwest Florida. Honey bee, Apis melifera L., activity was monitored for two days following each application and yield and fruit quality were determined. On only a few occasions was increased honey bee activity noted. Application of bee attractant increased total yield in one field in central Florida and resulted in an increase in early yield at all three locations in southwest Florida. Soluble solids content of mature fruit was not directly affected by treatment. Treatment increased the seed content of fruit from three of five farms.
INFLUENCE OF CULTIVARS, FLOODING, AND TIME OF FLOODING ON SWEET POTATO YIELD
Authors: Roberts Warren , Russo Vincent
Published: February 2019

Sweet potatoes are an important crop in the southern U.S. The southern U.S. is subject to heavy rainfall at any time during the production season, and soils could be flooded for days. Previous work has shown that sweet potatoes flooded just prior to harvest exhibited increased decay during curing and storage. This study was designed to determine the effects of flooding at both mid-season and late-season on sweet potato yield. Four cultivars were grown in both 1989 and 1990. Each cultivar received a control treatment (no flooding), flooding halfway through the production season, and flooding just prior to harvest. Flooding was continuous for approximately 6 days. Yield was not significantly affected by late season flooding, but mid-season flooding reduced yields of all varieties. Yield reduction due to flooding at mid-season was in excess of 35% in 1989 and in excess of 50% in 1990.
INTERMITTENT WARMING OF RETAIL-PACKAGED FRUIT DOES NOT AFFECT STRAWBERRY FRUIT QUALITY DURING STORAGE.
Authors: Perkins-Veazle P. , Collins J.K.
Published: February 2019

The effects of retail-display packaging on strawberry fruit quality were studied using freshly harvested `Cardinal' strawberries. Fruit free from blemishes and disease were placed into plastic vented boxes, covered with vented plastic lids or plastic wrap, and placed at 1 and 5C overnight One-half of the treatments were removed from coolers, held at 25C for eight hours, returned to the coolers and evaluated over a 15-day storage period. The plastic overwrap greatly decreased weight loss during 15 days of storage; carbon dioxide reached 0.8 and 2% per mg fresh weight at 1 and 5C, respectively. Type of cover did not affect overall appearance or disease ratings. Exposure of fruit to 25C for eight hours led to no loss of overall quality. Storage of fruit at 50C led to greater disease incidence and loss of quality. The respiration rate of fruit warmed at 25C reached equilibrium after six hours, regardless of initial storage temperature. Fruit in vented dome-lid boxes had more weight loss than plastic-wrapped boxes at both temperatures.
YIELD RESPONSES AND NUTRIENT UPTAKE OF TRIPLOID WATERMELON AS AFFECTED BY FERTILIZER SOURCE, MULCH, AND ROW COVER
Authors: Earhart D. R. , Dainello F. J. , Baker M. L.
Published: February 2019

Response of triploid watermelon [Citrullus lanatus (Thunb.) cv. Tiffany] to fertilizer source (FS) [poultry litter (PL) vs. commercial fertilizer (CF)1, black plastic mulch (BPM), and spunbonded floating row cover (SFC) was evaluated in 1990 on an East Texas Fuquay-Darco sandy loam soil. Plant growth and percent soluble solids were equated by FS. Vine fresh weight, number and total melon weight per plot, average melon weight, and percent soluble solids were increased 27%, 29%, 45%, 24%, and 17%, respectively, by BPM when compared to no mulch treatment. BPM + SFC treatment decreased vine fresh weight but increased total melon number which in turn increased plot weight. PL increased plant P, K, and Mg 16%, 12%, and 24%, respectively, when compared to CF. Plant Ca was increased 21% by CF. Plant N, P, Ca, and Mg were increased 18%, 16%, 22%, and 15% by the use of BPM. A reduction in plant N was found when SFC was used alone and with treatments lacking BPM or BPM + SFC. Mean soil temperature was increased on the average 2°C at 10 cm depth by BPM when compared to all other treatments. Mean 24 hr air temperature 2 cm above BP and bare ground under SFC was increased 5°C above ambient.
INFLUENCE OF NITROGEN APPLICATION TIME AND PHOSPHORUS RATE ON PECAN
Authors: Smith Michael W.
Published: February 2019

Thirty-five-year-old `Hayes' and `Patrick' trees (22 trees/ha) were fertilized with 112 kg N/ha (NH4NO3) either the second week of March or the first week of Oct each year. Phosphorus was applied (broadcast) during March 1986 and again during May 1989 at 0 or 244 kg P/ha. Treatments were arranged in a split-split-plot design with four single-tree replications. Leaf N concentration and the number of shoots/1-year-old shoot were not affected by N application time, and the effect on shoot length was inconsistent. Total yield and annual yield three of five years were greatest from `Hayes' when N was applied during Oct rather than March. Yield of `Patrick' was unaffected by time of N application. Phosphorus application increased soil P up to 20 cm deep, and leaf P concentration was increased three of five years in `Hayes' and two of five years in `Patrick'. Shoot growth, number of new shoots, nut size, kernel percentage, and yield were generally not affected by P application.
EFFECTIVENESS OF DIFFERENT ZN FERTILIZERS AND TWO METHODS OF APPLICATION IN THE CONTROL OF `LITTLE-LEAF' IN PEACH TREES IN SOUTH TEXAS
Authors: Arce Juan Pablo , Storey J. Benton , Lyons Calvin G.
Published: February 2019

Fall soil treatments of ZnEDTA and ZnSO4 at three increasing rates (32.2, 64.4 and 128.8 g. Zn/tree) and 1, 2 and 3 spring foliar sprays of NZN (0.35 g. Zn/tree/application) were tested to correct Zn deficiency in three year old `Earligrande' peach trees. All Zn carriers increased the Zn leaf content. Peach trees treated with three applications of NZN were equal to the medium or high rates of soil applied ZnEDTA or ZnSO4 respectively, in appearance, chlorophyll content and foliar Zn content. Three applications of NZN at 0.35 g. of Zn/tree (473 ml/378 gal H2O) gave excellent tree response and was cost effective.

Authors: Foster William J. , Ingram Dewayne L. , Nell Terril A.
Published: February 2019

Rooted stem cuttings of Ilex crenata Thunb. `Rotundifolia' were grown in a controlled-environment growth chamber. Root-zone temperatures were controlled with an electric system. Shoot carbon exchange and root respiration rates were determined in response to root-zone temperatures of 28, 32, 36, and 40C for 6 hour·day–1 for 7 days. Photosynthesis was decreased by root zones ≥ 32C, while root respiration increased with increasing root-zone temperature. Decreased photosynthetic rates were not due to increased stomatal resistance.
