title: Fruit yield and bacterial wilt symptoms on eggplant genotypes grown in soil infested with Ralstonia solanacearum

description: Fruit yield and bacterial wilt symptoms of eggplant genotypes CNPH006, CNPH171, CNPH658, CNPH778, CNPH783, and CNPH785 were quantified in soil naturally infested with Ralstonia solanacearum(race 1, biovar 3) in Brasília, Brazil.Exceptfor CNPH778, all genotypes developed at least one typical wiltedplant. Besides wilt,other symptoms considered for assessing levels of tolerance/resistance among genotypes wereplant death (CNPH006, CNPH171, CNPH658 and CNPH783), leaf chlorosis(CNPH785) and plant dwarfing (all genotypes). The occurrence of bacterial ooze on cut stems was observed in all plants grown in infested beds, including those that did not exhibit wilt symptoms. Plants grown simultaneouslyin noninfested beds of the same dimensions and soil characteristics allowed the comparison ofyield losses due to the pathogen. The genotypes were grouped according to their ability to maintain fruit production in the infested area. CNPH785 was the most tolerant genotype, with no significant loss due to the disease,followed by CNPH783, CNPH778 and CNPH171, with mean losses of 19.3%, 11.4%, and 10.1%, respectively. The genotypes CNPH658 and CNPH006 were the most susceptible, with average losses of 99.53 and 99.32%, respectively.

title: Oncidium sarcodes x Oncidium Aloha 'Iwanaga': new option of Oncidium hybrid

description: Oncidium genus has about 315 species and hundreds of hybrids. Breeding of native species with ornamental potential is an important strategy to ensure a better adaptability of cultivars to Brazilian conditions. Among them, the Brazilian species Oncidium sarcodes stands out for long stems with large yellow flowers with brown stains. The aim of this work was to characterize the progenies resulting from the oncidiums hybridization in order to select a potential cultivar. Selected O. sarcodes plants were used as the female parental and O. Aloha 'Iwanaga' as the male parental. Pollination was manually controlled and the obtained seeds were germinated in vitro. After seedling establishment in vitro and acclimatization in the greenhouse, they were transplanted to plastic pots with volume of 1000 mL using as substrate pine bark and coconut fiber 1:1 (v/v). For the morphological description of the hybrids, 10 progenies were selected to evaluate the characteristics of vegetative development and inflorescences. Flowering occurred 48 months after germination, from December to January, flowers with durability of 25 to 30 days. The crossing brought flowers to a greater balance and symmetry between the verticils. The sepals and petals have yellow gold color with brown spots, with well-defined limits between the colors.

title: Comparative effectiveness of commercial tomato rootstocks to control bacterial wilt

description: Bacterial wilt, caused by Ralstonia solanacearum, is one of the main diseases of solanaceous crops in Tropical regions, being the major limiting factor for tomato production in the North Region of Brazil. The disease has also been a constraint to tomato production under protected cultivation, which had solid expansion in the South and Southeast regions in the last decades. Although sources of resistance to bacterial wilt have been identified in S. lycopersicum germplasm, no resistant cultivars are available to growers. However, commercial rootstocks are available to protect scions against the disease, thus reducing the incompatibility associated to the use of different Solanaceae species/genera. The main objective of the present work was to evaluate the levels of resistance of a group of commercial hybrid/inbred tomato rootstocks to a diverse array of five R. solanacearum isolates (all obtained from infected tomato plants). A clear discrimination was observed among the evaluated rootstocks in relation to disease incidence. The phenotypic reaction of the tomato rootstocks was isolate-specific. The tomato hybrids 'Muralha' and 'Guardião' and the inbred line 'Hawaii 7996' (international resistance standard) were the rootstocks with best performance against the majority of the five R. solanacearum isolates, displaying significantly better resistance when compared with the hybrids 'Magnet' and 'Protetor'. However, all rootstocks were highly susceptible (100% mortality) to the R. solanacearum CNPH 488 isolate (classified as race 1 / Biovar 2, collected in Paraná State, Brazil). The same set of rootstocks was also evaluated under artificially infested soil (with less intense inoculum pressure). The hybrids 'Guardião' and 'Muralha' repeated their good performance when compared with 'Magnet' and 'Protetor'. Our results reinforce the notion that under favorable environmental conditions and/or in the presence of highly virulent strains, the system based upon tomato scion grafted onto tomato rootstock might provide unsatisfactory levels of bacterial wilt control. Therefore, complementary and preemptive control measures will be necessary in order to reduce the initial inoculum pressure in the soil.

title: Multivariate grouping of curves in the study of post-harvest conservation of lettuce cultivars

description: One of the main problems for the commercialization of lettuce is the short shelf life due to loss of quality. One way to study the decline of plant quality in function of time after harvest is the graphical method, however this strategy may become difficult if a great number of treatments is evaluated. So, the grouping of curves using multivariate analysis can be a viable alternative. The objective of this work was to select lettuce cultivars presenting better post-harvest conservation through multivariate clustering curves. Fifteen lettuce cultivars were evaluated in terms of cumulative loss of fresh matter (PAMF) and discoloration degree (GD) during 72 hours after harvest. Thirteen regression models were adjusted, checking the best fit of the first-degree polynomial model for the PAMF and the logistic model for the GD. For both traits, the cultivars were grouped into six groups. The cultivars 'Romana Balão' and 'Vitória de Santo Antão' are the most resistant to dehydration and discoloration in storage at environmental temperature, being recommended to production, marketing and as parents in breeding programs.

title: Diagnosis of vegetable production in the metropolitan region of Belo Horizonte, Brazil

description: The production chain of vegetables in the metropolitan region of Belo Horizonte is characterized by the cultivation of tuberous vegetables, herbs and fruits, considered one of the green belts of the state of Minas Gerais, Brazil. This study aimed to obtain a diagnosis of the current situation of producers in that region, analyzing aspects of production, marketing and characterization of producers. The research was carried out using a structured questionnaire applied in situ from January to December 2013 within a representative group of producers indicated by EMATER-MG. A quantitative evaluation of the research was made and presented in the form of figures and tables. Based on the obtained information, most of metropolitan vegetable producers were over 39 years old, basically with elementary education level, and the main grown vegetable is lettuce. The commercialization of the vegetables was carried out in the metropolitan region directly to the final consumer. Thus, the study contributed to expand the understanding of production and commercialization of vegetables. Based on the obtained information, the authors suggest comparation between different regions of Minas Gerais could be carried out by further studies.

title: Selectivity of oxyfluorfen in pre transplant of broccoli

description: As most vegetables, broccoli (Brassica oleracea var. italica) suffers great loss of productivity in the presence of weeds; an appropriate weed management being necessary. The objective of this study was to evaluate the selectivity of oxyfluorfen herbicide applied in pre transplant of broccoli, hybrid Avenger, on different transplantation periods. The experiment was carried out in a greenhouse, in Universidade de Caxias do Sul, situated in Vacaria, Rio Grande do Sul State, Brazil, from August to October 2012. The experimental design was completely randomized in a factorial 11x2 with three replications. The factor A was composed of 11 periods of transplantation (0 to 10 days after application of the product) and the B with and without herbicide (3 L/ha). We evaluated visual symptoms of phytotoxicity in plants, plant height, weight of fresh mass of shoots and dry weight of shoots and root. Plant material was collected from all treatments and analyzed 30 days after transplantation. The herbicide oxyfluorfen does not cause phytotoxic effects on broccoli, hybrid Avenger, when applied to soil in pots, under pre-transplanting.

title: Postharvest conservation of cherry tomato fruits coated with cassava starch film

description: ABSTRACT: Tomato is a highly perishable fruit. As a climacteric fruit, the ripening process involves a series of changes in its physical and chemical characteristics. Thus, the main goal of this study was to evaluate the longevity and postharvest quality of cherry tomato fruits after applying cassava starch film under room and controlled temperature conditions. Cultivars 'Perinha Água Branca' and 'Mascot' were harvested at physiological maturity and used in this study. Cassava starch was applied at 0%, 1%, 3% and 5% followed by assessments at 0, 4, 8, 12, 16, 20 and 24 days in two separate trials: one under room temperature (25±2°C) and the other under controlled condition (12°C and 90% RH). The experimental design was completely randomized, with three replications containing 8 fruits per package in a 2x4x7 factorial. Fresh weight loss, titratable acidity, soluble solids, pectinmethylesterase activity (PME) and the relation between soluble solids and titratable acidity were evaluated. Weight loss of 'Mascot' was higher in fruit coated with 3% and 5% of starch, at room temperature and a lower PME activity was observed. Acidity was lower at 3% and 5% in 'Mascot' and 'Perinha' at controlled temperature. The treatment at 5% provided the lowest postharvest longevity, whereas the treatment at 1% was similar to control in both conditions evaluated. The treatment at 3% preserved quality parameters such as lower acidity and lower PME activity and was considered the most effective treatment.

title: BRS Juruti: the first Brazilian habanero-type hot pepper cultivar

description: ABSTRACT: The Habanero hot pepper group is not well known in Brazil, despite its origin in the Amazon. Nevertheless, domestic and international markets have been increasing the demand for this type of hot pepper. The Brazilian agroindustry is interested in supplying part of this demand with high quality products and competitive prices, and it needs well-adapted cultivars. To fill this gap, Embrapa Vegetables developed the Habanero pepper cultivar BRS Juruti, which meets the demands of both the market for fresh fruit and the processing agroindustry of mash and sauces. Cultivar BRS Juruti has red fruits and yielded around 50 t/ha (36,000 plants/ha). Fruit pungency is circa 260,000 SHU and fruits have high content of vitamin C (122 mg/100 g). BRS Juruti is resistant to several viruses, Oidiopsis sicula, and Meloidogyne javanica, and presents intermediate resistance to key bacterial diseases; and is highly uniform in comparison with the original population. Cultivar BRS Juruti is recommended for open field (specially adapted to the Central Region of Brazil), as well as greenhouse/screenhouse cultivation. BRS Juruti has been registered (RNC 32010) and protected (DOU 01/09/2015) in theBrazilian Ministry of Agriculture, Livestock and FoodSupply (MAPA). Breeders' seed is being made available to interested parties in the private sector.
