| The use of abscisic acid (ABA) in agriculture has increased in the last few years due to the increase in ABA commercial availability at lower costs. The objective of this study was to determine the effect of exogenous ABA on tomato fruit quality parameters such as soluble solids (SS), total and soluble pectins, titratable acidity (TA) and flesh firmness. Tomatoes from the cultivar ?Santa Clara? were the study followed a complete randomized block desig, with four treatments in five repetitions. The treatments were plants not treated with ABA (control), foliar sprayed with ABA at 500 mg L -1, 150 mLdrench with ABA at 500 mg L-1, or foliar plus drench treated with ABA. After harvesting, the physicochemical characteristics of the fruits were evaluated in the... |

| O tomate encontra-se presente na alimentação de diversas populações, destinado ao consumo in natura ou a agroindústrias. Em virtude da variabilidade genética e condições edafoclimáticas no cultivo, os teores de constituintes químicos dos frutos são variáveis, refletindo no sabor, cor, textura e odor (Guilherme et al., 2014). Desse modo, objetivou-se avaliar a aceitação sensorial dos frutos de cultivares de tomates cultivadas no Amazonas, sob um painel de consumidores locais. |

| RESUMEN La contaminación de los suelos por metales pesados es un resultado de la actividad humana, agricultura e industria. Entre los metales pesados el plomo es un contaminante potencial que en las plantas ocasiona numerosos síntomas de toxicidad como por ejemplo, crecimiento atrofiado, ennegrecimiento del sistema radical y clorosis generalizada. La actividad de las enzimas superóxido dismutasa (SOD; EC 1.15.1.1) y glutatión reductasa (GR; EC 1.8.1.7) se determinaron en hojas y tallos de plantas de tomate cv. Amalia utilizando tres concentraciones de plomo (PbAc2) (0, 50 y 100 mg/kg). Las plantas de tomate se sembraron en el periodo de septiembre-diciembre del 2010 en condiciones de invernadero, las aplicaciones del metal se realizaron dos veces por... |

| ABSTRACT: This study carried out agronomic evaluation and estimated the combining ability of tomato lines for the industrial segment, aiming to elect promising genotypes for breeding and to find simple hybrids with superior traits. Randomized-blocks design was used with 57 treatments (45 experimental hybrids, 10 lines and 2 checks treatments) with 3 replications. A complete diallel among 10 tomato lines for processing was used. Evaluated traits were: fruit total (YT) and commercial production (YC), pulp yield (YP), fruit average mass (MM) and total soluble solids content (TSS). Diallel crosses allowed synthesizing experimental hybrids with superior traits when compared to commercial hybrids. Non-additive effects prevailed over the expression of YT, YC, YP... |

| ABSTRACT The genotypes evaluation in a germplasm bank is essential to determine their commercial or usefulness, as potential parents, in a breeding program. We aimed to detect the genetic diversity of 42 tomato genotypes of cherry type, belonging to the germplasm bank of the Federal University of Uberlândia and, also evaluate their behavior. The experiment was conducted in a greenhouse in randomized block design with 42 treatments and two replications. Ten quantitative traits of agronomic importance were evaluated. The genetic divergence was obtained by multivariate analysis, using the Mahalanobis distance with different clustering methods (UPGMA and Tocher). The hybrids performance was compared by Scott-Knott (p= 0.05) and Dunnett’s test (p= 0.05). UPGMA... |

| ABSTRACT High doses of nitrogen, phosphorus and potassium in irrigated systems may lead to an increase in the productivity of industrial tomatoes, but may also alter the final quality of the fruits. The objective of this was to evaluate the agronomic yield and post-harvest quality of industrial tomatoes, under NPK doses for climatic conditions of Northern Minas Gerais state, Brazil. The study was conducted in the city of Jaíba, MG, Brazil, in randomized block design with four repetitions in a 3 x 3 factorial scheme, consisting of three doses of N (90, 135 and 180 kg ha-1), of P (270, 405 and 540 kg ha-1) and of K (225, 337 and 450 kg ha-1), corresponding to 50, 75 and 100% of the fertilization recommendation; and three tomato hybrids: BRS Sena, Heinz 9553... |

| ABSTRACT: Fruit bagging is an efficient mechanical control technique used in fruit growing. However, to date, few studies have evaluated the efficacy of bagging in the cultivation of vegetables, including tomato crops. The objective of this study was to evaluate the effectiveness of bagging of tomato flowers and/or fruits using a non-woven fabric (NWF) for the control of Helicoverpa spp., Neoleucinodes elegantalis, and Tuta absoluta, to evaluate the effect of this technique on the final yield, and determine the optimal period for bagging. Tests were conducted in a commercial crop of staked ‘Valerin’ tomato plants located in the municipality of Ubajara, Ceará State, Brazil. The experimental design was randomized blocks with a 2x4 factorial design (sprayed... |

| Antioxidant system is involved in arbuscular mycorrhizal symbiosis, but its role during the colonization process is still poorly understood. To gain new insights into the role of antioxidant system during root colonization by arbuscular mycorrhizal fungi, the activities of key antioxidant enzymes were evaluated in tomato (Solanum lycopersicum L.) roots inoculated with six strains of different genera and species: two Glomus mosseae, Glomus cubense, Glomus intraradices, Glomus sp. and Acaulospora scrobiculata. Glomus cubense and A. scrobiculata strains reached the highest infectivity levels with maximum values of colonization frequency and intensity of 29-10.88% and 18-9.20%, respectively; G. mosseae strains showed an intermediate infectivity, both with 15%... |

| AbstractTomato bacterial spot on tomato may be caused by four species of Xanthomonas and among them X. gardneri(Xg) is the most destructive one, especially in areas irrigated using a center pivot system in Minas Gerais state and the midwest region of Brazil. Due to the ineffectiveness of chemical control and the lack of cultivars with high levels of genetic resistance, this study investigated the potential of three antagonists (Streptomyces setonii (UFV618), Bacillus cereus (UFV592) and Serratia marcescens (UFV252)), and the hormone jasmonic acid (JA) as a positive control, to reduce bacterial spot symptoms and to potentiate defense enzymes in the leaves of tomato plants infected by Xg. Tomato seeds were microbiolized with each antagonist, and the soil was... |

| RESUMO Devido à carência de informações sobre tecnologia de aplicação na horticultura, objetivou-se com essa pesquisa avaliar o efeito de três técnicas de aplicação em diferentes partes do dossel do tomateiro cultivado em ambiente protegido. As técnicas avaliadas foram 1= Lança manual com duas pontas de jato cone vazio, JA-2 (700 kPa), taxa de aplicação de 618 L ha-1; 2= Barra vertical com seis pontas de jato cone vazio, ATR 0.5 (700 kPa), taxa de aplicação de 493 L ha-1; 3= Barra vertical com seis pontas de jato plano simples, AXI 11002 (400 kPa), taxa de aplicação de 1442 L ha-1. Como indicadores de qualidade da aplicação, foram mensurados o depósito relativo (quantitativo) e a cobertura (qualitativa) das folhas do tomateiro nas posições de coleta... |
