Authors: Srinivasan M. , Kumar K. , Kumutha K. , Marimuthu P.
Published: April 2018

Arbuscular mycorrhizal fungi are soil fungi distributed worldwide, forming symbiosis with most of the vascular plants for their growth and survival, which is used for sustainable agriculture and ecosystem management. This study investigated the establishment of monoxenic cultures of Glomus intraradices in association with transformed carrot hairy root. The G.intraradices spores were isolated from sugarcane rhizosphere by wet sieving and decanting technique and propagated in open pot culture. Transformation in to carrot hairy root was done using Agrobacterium rhizogenes. Surface sterilization of G.intraradices spores co-cultured with transformed carrot hairy root in Modified Strulla and Romand (MSR) medium was found the host root growth as well as for germination AM spores. After three months of incubation in dark condition, significant production of extensive hyphal growth on MSR medium and an average of 8500-9000 spores per petri dish was observed. The in vitro inoculum exhibited higher potential of root colonization due to numerous intraradices mycelium with extensive spore load. The produced monoxenic inoculum can be used in place of traditional system where it has a advantage of producing contaminant free propagulas. Thus the monoxenic culture system, a powerful tool, of AM sporulation, can be used for the mass production of monoxenic inoculum of AM fungi besides studying its biology.

Published: April 2018

A pot culture experiment was conducted to study the effect of combined use of organic manures with inorganic fertilizers on uptake of available nutrients and yield of groundnut crop at Tamil Nadu Agricultural College and Research Institute, Madurai during kharif season of 2008-2009. The experiment was laid out in completely randomized design (factorial) with two replications. Main pot treatments comprised of three types of manures viz, control ( M0 ), pressmud @ 5 t ha-1 ( M1 ), vermicompost @ 2 t ha-1 ( M2 ), farmyard manure @12.5 t ha-1 ( M3 ) and sub pot treatment comprised of 4 levels of K viz, 0 (K0), 100 ( K1 ) , 75 ( K2 ) and 50 kg of K20 ha-1 ( K3 ) with a recommended dose of fertilizer (RDF) respectively. The results revealed that highest nitrogen, phosphorus and potassium uptake of 1.01, 0.96 and 0.80 g/pot was recorded in the treatment that received 75 kg K2O ha-1 and Pressmud @ 5 t ha-1 (K1M1) and in the pots which treatment received K1M1 showed the highest Haulm and pod yield of (28.25 and 24.5 g/pot) of groundnut crop respectively.
Trend analysis of annual and seasonal rainfall to climate variability in North-East region of India
Authors: Patle G. T. , Libang A.
Published: April 2018

Global warming, climate change and its consequences are major threat for the global agriculture. The agriculture in the North-East region of India is supposed to more in danger due to its topographic features. Agriculture in the state of Arunachal Pradesh is dependent on rainfall and variability in rainfall due to climate change is expected to threaten the food production in future. This study examines the impact of climate change on rainfall using the trend analysis technique for the four districts of Arunachal Pradesh. For this purpose temporal trends in annual and seasonal rainfall were detected using nonparametric Mann-Kendall test at 5% significance level. The daily time series rainfall data for the period 1971-2007 were analyzed statistically for each district separately. The results of Mann Kendall test showed decreasing trend in annual mean rainfall in east Siang, upper Siang and lowers Dibang valley and no trend in the west Siang district over the period of 1971-2007. In case of east Siang, upper Siang and lower Dibang valley districts, decreasing trend of rainfall was observed in the post monsoon season with slope magnitude of 3.01 mm/yr, 3.32 mm/yr and 3.95 mm/yr respectively. Decreasing pattern of rainfall in post monsoon season may affect the vegetable and fruit production in the winter season.

Enhancing the vase life of cut foliages is one of the prime goals of floriculturist and it is very interesting and important aspect of floriculture.The efforts were made to find out best waxing treatment for enhancing the vase life along with excellent quality maintenance for few cut foliage species .The objective was to evaluate optimum percent wax solution for improving post harvest life and quality of ornamental plants. Different wax emulsion treatments (0.25, 0.50, 0.75 and 1.00 %) showed significant results in both quantitative and qualitative attributes of ornamental species. In Asparagus densiflorus ‘Sprengeri’ and Eucalyptus teritecornis,0.75% wax emulsion concentration recorded minimum foliage weight (5.62, 20.49 g) and minimum water uptake (5.60, 32.73 ml) respectively on 3rd day, while maximum foliage weight (0.90, 6.84 g) and maximum water uptake (1.13, 13.77 ml) was recorded on senescence day. In Caryota urens (Fishtail palm) 0.50% wax emulsion concentration recorded minimum foliage weight (9.71 g), minimum water uptake (6.53 ml) on 3rdday, while maximum foliage weight(1.83 g) and maximum water uptake (1.20 ml) on senescence day. In Heliconia psittachroum cv. Golden Torch, 1.00 % wax emulsion concentration recorded minimum foliage weight (28.85 g), minimum water uptake (20.35 ml) on 3rdday, whereas maximum foliage weight (15.83 g)and maximum water uptake (5.75 ml) on senescence day. There was improvement and increament in post harvest quality and vase life of studied ornamental cut foliages.
Changes in protein profile and RNA content of Apis mellifera worker pupa on parasitization with Tropilaelaps clareae
Authors: Negi Jamuna , Kumar Neelima R.
Published: April 2018

Tropilaelaps infestation of Apis mellifera pupa caused reduction in total protein concentration of the infested pupa. This may be due to protein feeding by mite. The additional protein fractions observed by SDS-PAGE and the difference in the nature of free amino acids suggested synthesis of newer proteins perhaps related to the stress response of the host. This opinion is strengthened by the increase in concentration of RNA ( 184.580±36.987 in non-infested pupa and 293.402±50.329 in infested pups) observed in the present study which was responsible for increased transcription of genes encoding antiparasite peptides as reported by other workers.

Authors: Banstola Laxman
Published: April 2018

Background:   This study aims to establish correlation of ultrasonography guided fine needle aspiration cytology (USG-FNAC) of thyroid nodules with histology. USG-FNAC was carried out in fifty cases of thyroid nodules and the result of USG-FNAC was compared with histopathology.Materials and Methods:  The study was performed in the Department of Pathology, National Academy of Medical Sciences, Bir Hospital over a period of one year. Fine needle aspiration of solid area of thyroid nodule was done in each case with USG guidance. FNAC results were classified according to Bethesda system of reporting. Finally, comparison was done between cytological and histological findings.  Results: The age of patients that underwent thyroidectomy ranged from 16 - 70 years. Maximum number of cases fell in age group 31-40 years. Female patients outnumbered male patients by a ratio of 9: 1.On cytological study, 70% cases were diagnosed as benign, 28% as malignant and 2% as inadequate for evaluation. On histopathology, 70% cases of diagnosed cases were benign lesions.  Nodular hyperplasia and colloid goiter were kept under the term ‘follicular nodule’. Follicular nodule was the most commonly diagnosed thyroid lesion. Fifteen cases of nodular hyperplasia and fourteen cases of colloid goiter were detected. Total number of malignant cases diagnosed was 15, out of which papillary carcinoma was the commonest (66.67%). We found two cases of medullary thyroid carcinoma.Conclusion: Sensitivity and specificity of USG-FNAC was 93.33 % and 100 %, respectively. The study showed significant correlation between FNAC (USG-guided in this study) and histopathology.
Frequency Inertia Response Control of SCESS-DFIG under Fluctuating Wind Speeds Based on Extended State Observers
Authors: Sun Dongyang , Sun Lizhi , Wu Fengjiang , Zu Guangxin
Published: April 2018

Insufficient frequency regulation capability and system inertia reduction are common problems encountered in a power grid with high wind power penetration, mainly due to the reason that the rotor energy in doubly fed induction generators (DFIGs) is isolated by the grid side converters (GSCs), and also due to the randomness and intermittence of wind power which are not as stable as traditional thermal power sources. In this paper, the frequency inertia response control of a DFIG system under variable wind speeds was investigated. First, a DFIG system topology with rotor-side supercapacitor energy storage system (SCESS-DFIG) was introduced. Then a control strategy for frequency inertia response of SCESS-DFIG power grid under fluctuating wind speed was designed, with two extended state observers (ESOs) which estimate the mechanical power captured by the DFIG and the required inertia response power at the grid frequency drops, respectively. Based on one inconstant wind speed model and the SCESS-DFIG system model adopting the control strategy established, one power grid system consisting of three SCESS-DFIGs with different wind speed trends and a synchronous generator was simulated. The simulation results verified the effectiveness of the SCESS-DFIG system structure and the control strategy proposed.

Published: April 2018

The magnetic properties of nanowires (NWs) and square nanorings, which were deposited by focused electron beam induced deposition (FEBID) of a Co carbonyl precursor, are studied using off-axis electron holography (EH), Lorentz transmission electron microscopy (L-TEM) and magnetic force microscopy (MFM). EH shows that NWs deposited using beam energies of 5 and 15 keV have the characteristics of magnetic dipoles, with larger magnetic moments observed for NWs deposited at lower energy. L-TEM is used to image magnetic domain walls in NWs and nanorings and their motion as a function of applied magnetic field. The NWs are found to have almost square hysteresis loops, with coercivities of ca. 10 mT. The nanorings show two different magnetization states: for low values of the applied in-plane field (0.02 T) a horseshoe state is observed using L-TEM, while for higher values of the applied in-plane field (0.3 T) an onion state is observed at remanence using L-TEM and MFM. Our results confirm the suitability of FEBID for nanofabrication of magnetic structures and demonstrate the versatility of TEM techniques for the study and manipulation of magnetic domain walls in nanostructures.
The Duration of Energy Deposition on Unresolved Flaring Loops in the Solar Corona
Authors: Reep Jeffrey W. , Polito Vanessa , Warren Harry P. , Crump Nicholas A.
Published: April 2018

Solar flares form and release energy across a large number of magnetic loops. The global parameters of flares, such as the total energy released, duration, physical size, etc., are routinely measured, and the hydrodynamics of a coronal loop subjected to intense heating have been extensively studied. It is not clear, however, how many loops comprise a flare, nor how the total energy is partitioned between them. In this work, we employ a hydrodynamic model to better understand the energy partition by synthesizing Si iv and Fe xxi line emission and comparing to observations of these lines with the Interface Region Imaging Spectrograph (IRIS). We find that the observed temporal evolution of the Doppler shifts holds important information on the heating duration. To demonstrate this, we first examine a single loop model, and find that the properties of chromospheric evaporation seen in Fe xxi can be reproduced by loops heated for long durations, while persistent redshifts seen in Si iv cannot be reproduced by any single loop model. We then examine a multithreaded model, assuming both a fixed heating duration on all loops and a distribution of heating durations. For a fixed heating duration, we find that durations of 100–200 s do a fair job of reproducing both the red- and blueshifts, while a distribution of durations, with a median of about 50–100 s, does a better job. Finally, we compare our simulations directly to observations of an M-class flare seen by IRIS, and find good agreement between the modeled and observed values given these constraints.
Plasma Heating and Alfvénic Turbulence Enhancement During Two Steps of Energy Conversion in Magnetic Reconnection Exhaust Region of Solar Wind

Published: April 2018

The magnetic reconnection exhaust is a pivotal region with enormous magnetic energy being continuously released and converted. The physical processes of energy conversion involved are so complicated that an all-round understanding based on in situ measurements is still lacking. We present the evidence of plasma heating by illustrating the broadening of proton and electron velocity distributions, which are extended mainly along the magnetic field, in an exhaust of interchange reconnection between two interplanetary magnetic flux tubes of the same polarity on the Sun. The exhaust is asymmetric across an interface, with both sides being bounded by a pair of compound discontinuities consisting of rotational discontinuity and slow shock. The energized plasmas are found to be firehose unstable, and responsible for the emanation of Alfvén waves during the second step of energy conversion. It is realized that the energy conversion in the exhaust can be a two-step process involving both plasma energization and wave emission.
Two-dimensional Nonlinear Simulations of Temperature-anisotropy Instabilities with a Proton-alpha Drift
Authors: Markovskii S. A. , Chandran Benjamin D. G. , Vasquez Bernard J.
Published: April 2018

We present two-dimensional hybrid simulations of proton-cyclotron and mirror instabilities in a proton-alpha plasma with particle-in-cell ions and a neutralizing electron fluid. The instabilities are driven by the protons with temperature perpendicular to the background magnetic field larger than the parallel temperature. The alpha particles with initially isotropic temperature have a nonzero drift speed with respect to the protons. The minor ions are known to influence the relative effect of the proton-cyclotron and mirror instabilities. In this paper, we show that the mirror mode can dominate the power spectrum at the nonlinear stage even if its linear growth rate is significantly lower than that of the proton-cyclotron mode. The proton-cyclotron instability combined with the alpha-proton drift is a possible cause of the nonzero magnetic helicity observed in the solar wind for fluctuations propagating nearly parallel to the magnetic field. Our simulations generally confirm this concept but reveal a complex helicity spectrum that is not anticipated from the linear theory of the instability.
Benchmark Linelists and Radiative Cooling Functions for LiH Isotopologues
Authors: Diniz Leonardo G. , Alijah Alexander , Mohallem José R.
Published: April 2018

Linelists and radiative cooling functions in the local thermodynamic equilibrium limit have been computed for the six most important isotopologues of lithium hydride, 7LiH, 6LiH, 7LiD, 6LiD, 7LiT, and 6LiT. The data are based on the most accurate dipole moment and potential energy curves presently available, the latter including adiabatic and leading relativistic corrections. Distance-dependent reduced vibrational masses are used to account for non-adiabatic corrections of the rovibrational energy levels. Even for 7LiH, for which linelists have been reported previously, the present linelist is more accurate. Among all isotopologues, 7LiH and 6LiH are the best coolants, as shown by the radiative cooling functions.
Epistemological Development in First-Year Nursing Students Undertaking Cultural Safety Education
Authors: Greenwood Sallie , Fyers Katrina
Published: April 2018

Background:

The process of teaching cultural safety is emancipatory, focused on wider social relations and the context in which they arise. As teachers of cultural safety, we are interested in the way that ideas are formed, held, and changed. The aim of this research was to examine whether epistemological shifts were demonstrated by nursing students over one semester of cultural safety teaching–learning.

Method:

NVivo software was used to analyze 34 nursing students' reflective journals, applying a cognitive–developmental framework. The framework comprised three epistemological positions—dualism, relativism, and propositional—and two in-between locations, referred to as stretching.

Results:

The results showed student movement between early epistemological positions and students' efforts to stretch to new, yet untried, ways of thinking.

Conclusion:

In the classroom, these shifts may be subtle; thus, paying careful attention to evidence that students are trying out new ways of thinking is essential. Appreciating that these small but significant shifts are perhaps more important than ‘aha’ moments is crucial. [

Engaging Nursing Students in a Culture of Integrity
Authors: Moore Holly Ann , Gaviola Melissa Spratt
Published: April 2018

Background:

In order to become safe, effective professionals, nursing students must have a working knowledge of academic and professional integrity principles. However, nursing students have knowledge gaps in these areas, which may lead to unethical practices postgraduation. Inconsistencies in faculty enforcement of integrity principles may lead to student confusion and further student risk.

Method:

An interactive online integrity course was designed to address knowledge gaps related to academic and professional integrity. Course engagement occurred through self-reflection, quizzes, and a commitment statement. The pilot course was deployed to all nursing faculty and staff for feedback and approval.

Results:

Of the 38 faculty and staff invited, 20 participated in the course. Based on feedback, course adjustments were made to address navigation, quiz clarity, and content. The online integrity course received full faculty approval.

Conclusion:

An interactive online integrity course is one option to support student engagement in and assimilation to a culture of integrity. [

Anesthesia in Mowat-Wilson Syndrome: Information on 11 Italian Patients
Authors: Spunton Marianna , Garavelli Livia , Mainardi Paola Cerutti , Emmig Uta , Finale Enrico , Guala Andrea
Published: April 2018

Mowat-Wilson syndrome is a genetic disease caused by heterozygous mutations or deletions of the ZEB2 gene and characterized by typical clinical features. The congenital malformations typical of this syndrome call for early diagnostic and surgical procedures requiring general anesthesia, but few information about the anesthesiology management of such patients is available. We enrolled 11 families of patients with Mowat-Wilson syndrome who had undergone surgical or diagnostic procedures requiring general anesthesia, and sent them a retrospective questionnaire including 16 open questions about the procedures. They were further contacted by phone for a semi-structured interview. A total of 37 procedures requiring general anesthesia was reported in 11 patients. Only two patients reported anesthesia-related complications during the procedure. No true additional anesthesia-related risk was present for the patients with MW syndrome, besides difficult intubation, weaning and lower respiratory tract infection. Perception of risk, however, is derived by non-medical observation on the part of the parents.
The indigenous Afrikaans film: Representation as a nationalistic endeavour
Authors: Van Coller Hendrik P. , Van Jaarsveld Anthea
Published: April 2018

Within the South African context, Afrikaans films unabashedly and predominantly served Afrikaner nationalism. Given the South African historical and political background, it is evident that Afrikaner nationalism has almost become an obscene term because of its association with the National(ist) Party and its apartheid policy: emblematic of an ideology and policy that has been rejected worldwide and has even been compared – albeit a skewed comparison – to National Socialism. In this article, the different stages that emancipation of a formerly colonised literature goes through, according to Amuta (1989), Ashcroft (1989) and Brink, will be discussed in detail with reference to the Afrikaans films, Geboortegrond (1946) and Hans die skipper (1952). In this process of representation, the historical past is re-assessed and laid to rest with far-reaching philosophical, ideological and poetical implications. In order to discuss the representation of this contextually bound discourse, mention will be made regarding important relevant theoretical concepts such as semiotics, discursive formations, literary reception and processing, reportorium, horizon of expectation and habitus.
Not One, Not Two: Toward an Ontology of Pregnancy
Authors: Sidzinska Maja
Published: April 2018

Basic understandings of subjectivity are derived from principles of masculine embodiment such as discreteness. But pregnancy challenges such understandings because it represents a sort of splitting of the body. In the pregnant situation, a subject may experience herself as both herself and an other, as well as neither herself nor an other. This is logically untenable—an impossibility. If our discourse depends on discrete referents, then what paradigms of identity are available to the pregnant subject? What could be the pregnant subject's ontology?
Eric Bapteste and John Dupré offer the idea that organisms are processual beings. In their view, the ecological interrelationships between the organisms are defining, and render them dynamic processes, rather than stable things. Does Bapteste and Dupré’s processual ontological account accommodate pregnant organisms, including pregnant subjects?
Here, I suggest some criteria for an ontology of pregnancy. I test the processual account and determine whether it can accommodate the phenomenon of pregnancy. I find that a processual ontology captures a great deal about pregnant embodiment and is a significant improvement over Cartesian and anti-metaphysical accounts. However, in order to accommodate pregnancy, what we still need from an ontology is the inclusion of subjectivity.

INDUSTRY
Authors: Gorzelany-Dziadkowiec Magdalena
Published: April 2018

The work contains an analysis of changes taking place in the bakery and confectionery industry based
on selected parameters in 2012 - Q1-Q3 2017. The aim of this study is an analysis of the factors determining
strategic choices among companies in the baking and confectionery industry. The subjects of the research
are enterprises of the above mentioned industry. As a research method, classical descriptive statistics
were used, based on PONT Info Ltd statistical data and industry reports. As a research technique, desk
research and observation were used using the analysis of structure indicators and intensity indicators.
The significant barriers to the bakery and confectionery market include the decline in bread consumption
over the years, as well as the lack of cooperation within the industry between large enterprises and small
businesses. An opportunity for the development of the analyzed industry is a growing export, basing the
strategy on the specialization of creating a unique product, as well as the combination of craft and modern
technologies and innovations – which is the most difficult.

The aim of the analysis presented in the study was to assess the scope and direction of changes in the level of
unemployment and in the size and structure of employment in peripheral areas on the example of the Warmian-
Masurian Voivodeship. The subject of the analysis was also the impact of changes on the labor market (expressed by
the decreasing size of unemployment) on the employee-employer relationship. The migration movements including:
migrations from abroad, internal rural-urban migrations, as well as outward migration causing depopulation of
rural areas and small towns were also assessed. The time range of the analysis covers the years 2016-2017 and
the basis of the analysis was data of the Statistics Poland and the Voivodship Labor Office in Olsztyn.
FACTORS DETERMINING THE AGRITO URISM ACTIVITY BY RURAL HOUSEHOLDS
ON THE EXAMPLE OF THE LUBLIN PROVINCE
Authors: Siedlecka Agnieszka , Wielogórska Gabriela
Published: April 2018

The level of income earned by rural households conducting agricultural activity is lower compared to other types of households. One of the ways to obtain additional financial resources in rural areas is the provision of tourist services (eg. agritourism). The rural areas of the Lubelskie Province are characterized by particularly favourable environmental conditions for the implementation of this type of activity. The aim of the article is to determine the factors influencing the decision to start agrotourism. A hypothesis was formulated that the factor which had the greatest impact on the decision was the need to obtain an additional source of income. Verification of the hypothesis was possible thanks to research carried out in the group of 51 household managers providing agrotourism services. The obtained empirical material allowed to conclude that the most important factor influencing the decision to start agritourism services was the attractive location of the farm household.

Introduction. The aim of the study was to evaluate concurrent recording of ENG and VNG measurements in selected diagnostic tests in healthy subjects so as to explore potential sensitivity and applicability of this kind of testing in the diagnostics of vertigo. Material and methods. The study was carried out in 50 healthy subjects including 24 women and 26 men aged 20-22 (mean age of 20.5 years) reporting no otorhinolaryngological organ-related complaints and no history of any balance disorders or vertigo. Every patient underwent subjective and objective otoneurological tests, electronystagmographic (ENG) examination including calibration, head-tracking test, optokinetic nystagmus test, rotatory chair test, positional tests according to Cawthorne and Rosen, and Hallpike caloric test as well as videonystagmographic (VNG) examination which included calibration, spontaneous nystagmus evaluation, head-tracking test, positional tests according to Cawthorne and Rosen with neck rotation test, and Hallpike caloric test. At first, ENG and VNG examinations were carried out separately at a 24-hour interval. Concurrent ENG and VNG recording was carried out 48 hours following the last test, with calibration being performed again before both evaluations. The concurrent recording included the spontaneous nystagmus evaluation, positional tests according to Cawthrone and Rose with the neck rotation test, and Hallpike caloric test. Results. No negative mutual interference of the conducted tests has been observed. Both in the concurrent and in the separate recordings, the caloric test revealed lower values of the mean velocity of the nystagmus free phase in the ENG test as compared to the VNG test. No signs of spontaneous nystagmus, as well as no signs of optokinetic and positional nystagmus, were detected in any case. Conclusions. The conducted tests did not reveal any mutual excludability between the selected ENG and VNG diagnostic tests upon concurrent recording. However, the concurrent use of both examinations in the diagnostics of balance disorders and vertigo requires further studies.

A serapilheira é uma das principais vias de retorno de nutrientes no sistema planta-solo-planta e sua determinação permite analisar a reestruturação de ambientes florestais antropizados. O conhecimento da produção da serapilheira é fundamental para determinar o potencial de regeneração de uma área por meio do aporte e ciclagem dos nutrientes. Objetivou-se neste estudo quantificar a produção de serapilheira e o aporte de carbono e dos nutrientes da fração foliar em áreas de ocorrência de Neossolos Quartzarênicos, com vegetação em diferentes estágios de regeneração, no Parque Nacional Serra de Itabaiana, em Sergipe. Em cada uma das áreas de Areias Brancas Abertas (ABA), Areias Brancas Intermediárias (ABI) e Areias Brancas Fechadas (ABF) instalaram-se coletores nos quais a serapilheira foi coletada mensalmente, de janeiro a dezembro de 2011. Em subamostras da serapilheira foram determinadas as quantidades de carbono (C), nitrogênio (N) e fósforo (P). Com a ação do fogo nas áreas de Areias Brancas do Parque da Serra de Itabaiana, ficou evidente que o mesmo altera o estado de equilíbrio dinâmico alcançado pelo ecossistema, logo, as condições nutricionais do solo são modificadas. Os acúmulos de C, N e P não apresentaram variação sazonal significativa, de acordo com a produção da serapilheira em cada área estudada, sendo que a área ABF proporcionou os maiores acúmulos destes elementos ao longo do período de avaliação.

A bromeliácea Encholirium spectabile Mart. ex Schult. & Schult. f. para que seja explorada comercialmente, pela indústria farmacêutica, necessita de estudos quanto a sua propagação via sementes com o intuito de estabelecer plantios comerciais. Os testes rápidos de vigor destacam-se por fornecer resultados rápidos e precisos que complementam os de germinação para melhor aferir o potencial fisiológico da semente. Objetivou-se avaliar o potencial fisiológico das sementes de Encholirium spectabile procedentes de Graça-CE e Serra Talhada-PE, através dos testes de lixiviação de potássio e pH do exsudato-fenolftaleína. Os experimentos foram conduzidos em delineamento inteiramente casualizado em arranjo fatorial (duas regiões geográficas e períodos de embebição). Para avaliação do teste do pH do exsudato-fenolftaleína as sementes foram embebidas por 15, 30, 45 e 60 minutos e as análises com base na lixiviação de potássio por 30, 60, 90, 120, 150 e 180 minutos de embebição imersas em 25, 50 e 75 mL de água destilada. Paralelamente, realizou-se a caracterização fisiológica das sementes por meio do teor de água, teste de germinação, índice de velocidade e tempo médio de germinação, comprimento da parte aérea e do sistema radicular e massa seca de plântulas. As sementes de Encholirium spectabile com poder germinativo semelhante foram classificadas em níveis distintos de vigor pelos testes de lixiviação de potássio e do pH do exsudato-fenolftaleína. Pelo teste de lixiviação de potássio, o período de embebição de 30 minutos foi eficiente para classificar as sementes de Encholirium spectabile quanto ao vigor, de acordo com a região geográfica de coleta, independentemente do volume de água utilizado.

Objetivou-se, neste estudo, avaliar os requerimentos nutricionais e o efeito da limitação de nutrientes no desenvolvimento de mudas de baru (Dipteryx alata Vogel) utilizando a técnica da limitação nutricional. O ensaio foi estabelecido em delineamento inteiramente casualizado com 12 tratamentos e oito repetições. Os tratamentos adotados foram os seguintes: completo 1 (C1 - adubado com N, P, K, S, B, Cu, Zn e calagem), completo 2 (C2 - adubado com N, P, K, S, Ca, Mg, B, Cu, Zn, sem calagem), tratamentos completos com omissão de um nutriente por vez (completo 1 - N, completo 1 - P, completo 1 - K, completo 1 - S, completo 1 - B, completo 1 - Zn, completo 2 - Ca, completo 2 - Mg, completo 1 - calagem) e controle (solo natural). Aferiu-se o diâmetro e a altura das plantas, separando-as em parte aérea e sistema radicular. As mudas foram secas, pesadas, moídas e foi determinado o teor de nutrientes na matéria seca da parte aérea. De acordo com os resultados, as limitações de S e B não afetaram o crescimento das mudas de Dipteryx alata. P e N foram, de forma geral, os nutrientes que mais limitaram o crescimento das mudas de baru. A sequência de exigência nutricional apresentada pelas mudas de baru, considerando a produção de biomassa seca da parte aérea, em ordem decrescente foi: P = N > Ca = Mg = Zn = K = S = B.
A NOGUEIRA-PECÃ NO BRASIL: UMA REVISÃO ENTOMOLÓGICA

Published: April 2018

As áreas plantadas com nogueira-pecã Carya illinoinensis (Wangenh.) K. Koch (Juglandaceae) vêm crescendo em todo o país, principalmente na região Sul. Com isso aumentam os riscos de incidência de pragas e doenças. Assim, o presente estudo objetivou revisar os aspectos importantes relacionados à cultura da nogueira-pecã, com ênfase nas espécies-praga e espécies benéficas de artrópodes relatados na sua região de origem e no Brasil. A partir do levantamento bibliográfico notam-se poucos registros de espécies-praga nocivas à cultura, grande parte, 18 espécies, são registradas para o Rio Grande do Sul, constituindo-se como uma ínfima parcela quando traçado um comparativo com as espécies já registradas e estudadas nos Estados Unidos, país de origem da espécie Carya illinoinensis, que somam mais de 66 espécies-praga, entre insetos e ácaros. Dentre as espécies-praga que merecem destaque estão o pulgão Monellia caryella, as espécies de filoxeras Phylloxera devastatrix e Phylloxera notabilis, pois são espécies que ocorrem tanto no Rio Grande do Sul, quanto nas regiões de origem da nogueira-pecã, causando danos às folhas das plantas. Ao mesmo tempo que se verifica uma alta diversidade de espécies-praga para a pecanicultura, é possível observar, tanto nos Estados Unidos, quanto no país, especialmente no Rio Grande do Sul, uma gama de potenciais predadores e parasitoides das espécies nocivas à Carya illinoinensis. Assim, sugere-se a utilização do Manejo Integrado de Pragas, com estudos futuros que priorizem a manutenção de agentes de controle biológico existentes nas áreas de plantio, buscando garantir nozes de qualidade e em quantidade, preservando a saúde do consumidor e do pomar.
