| 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... |

| Bactérias endofíticas promotoras de crescimento podem aumentar a eficiência nutricional das plantas, favorecendo sua produção. O objetivo deste trabalho foi avaliar a influência de 10 isolados de bactérias endofíticas, previamente selecionados como agentes promotores do crescimento de plantas, sobre a eficiência de absorção, utilização e translocação de nutrientes em plantas de tomateiros em casa de vegetação. Para a introdução das bactérias endofíticas em plântulas de tomateiro cv. Santa Clara, utilizou-se o corte do hipocótilo. Cinqüenta e cinco dias após o transplantio das seções de parte área, as plantas foram coletadas para a determinação da matéria seca da parte aérea e dos teores de macro e micronutrientes. Os teores de N, P, K, Ca, Mg, Cu e Zn na... |

| Biochemical responses inherent to antioxidant systems as well morphological and anatomical properties of photomorphogenic, hormonal and developmental tomato mutants were investigated. Compared to the non-mutant Micro-Tom (MT), we observed that the malondialdehyde (MDA) content was enhanced in the diageotropica (dgt) and lutescent (l) mutants, whilst the highest levels of hydrogen peroxide (H2O2) were observed in high pigment 1 (hp1) and aurea (au) mutants. The analyses of antioxidant enzymes revealed that all mutants exhibited reduced catalase (CAT) activity when compared to MT. Guaiacol peroxidase (GPOX) was enhanced in both sitiens (sit) and notabilis (not) mutants, whereas in not mutant there was an increase in ascorbate peroxidase (APX). Based on PAGE... |
