| ABSTRACT The use of bacteria in growth promotion and biological control of plant diseases can minimize environmental contamination caused by the indiscriminate use of pesticides and chemical fertilizers. We aimed to evaluate growth promotion and biological control of Corynespora cassiicola in tomato seedlings mediated by beneficial bacteria isolated from a non-rhizospheric Amazon soil containing different amounts of biochar, and to identify to which groups of bacteria the strains belong. We obtained 200 strains of bacteria from experimental plots containing biochar doses of 0, 40, 80 and 120 t ha-1. Of these, 53 strains were selected by root colonization tests. Based on growth promotion parameters, 25 strains were screened, identified by molecular... |

| The use of raw rice husk as substrate allows the use of crop systems that promote the recirculation of leachate in long crop cycles. Mini tomatoes present relatively low demand for photoassimilates. Thus, partial defoliation of the sympodium could benefit the crop without damage to the production or quality of the fruits. The objective of this work was to evaluate the plant growth, fruit yield and fruit quality of Cherry Hybrid Wanda and Grape Hybrid Dolcetto mini tomatoes cultivated in two recirculation crop systems (pots and troughs), using raw rice husk as substrate, under three defoliation conditions (without defoliation, removal of one and two leaves of the sympodium). The Cherry cultivar showed higher plant growth, fruit yield and mean fruit size.... |

| The objective of this study is to analyze the growth of wild species of tomato, of the cultivar Redenção and of the respective F1 hybrids of interspecific crossings. We evaluated six wild-type accessions (Solanum pimpinellifolium ‘AF 26970’, S. galapagense ‘LA-1401’, S. peruvianum ‘AF 19684’, S. habrochaites var. hirsutum ‘PI-127826’, S. habrochaites var. glabratum ‘PI-134417’, and S. pennellii ‘LA-716’) and the commercial cultivar Redenção (S. lycopersicum) together with their respective interspecific hybrids. In completely randomized blocks and plots subdivided by time (16, 28, 42, 56, 70, and 84 days after transplanting), we evaluated leaf area (LA), total dry matter (TDM), absolute growth rate (AGR), relative growth rate (RGR) and net assimilation rate... |

| Los avances en sistemas y recursos informáticos permiten desarrollar modelos para simular el comportamiento de los fluidos en invernaderos. Sin embargo, la predicción de los gradientes de masa y energía, en los invernaderos con el cultivo y ventilación natural, es difícil por la naturaleza estocástica del viento y las relaciones de dependencia entre la temperatura, CO2 y humedad relativa. Existen técnicas heurísticas, como las Redes Bayesianas, que ayudan a conocer las relaciones entre las variables que no pueden determinarse con herramientas estadísticas. El objetivo del presente estudio fue determinar la temperatura, concentración de CO2 y humedad relativa con respecto a la altura del cultivo, en un invernadero con ventilación natural, mediante Redes... |

| El cultivo de tomate (Solanum lycopersicum) en la Comarca Lagunera, Coahuila, México, es afectado por la cenicilla (Leveillula táurica). Para controlar esta enfermedad en la región se realizan aspersiones intensivas de fungicidas. Una alternativa para su manejo es el uso de genotipos tolerantes. En el presente estudio se evaluó el desarrollo epidémico y el rendimiento total y por calidades comerciales de tres cultivares de tomate tipo saladette, de hábito indeterminado (Sun 7705, Sahel y Romana Elite), cultivados en condiciones de agricultura intensiva a cielo abierto, sin aplicar fungicidas en la Comarca Lagunera. Los experimentos se establecieron en dos fechas de siembra durante 2006. El diseño experimental fue bloques al azar con cuatro repeticiones.... |

| En México existe diversidad de genotipos de jitomate (Solatium lycopersicum L.) con características sobresalientes de desarrollo de la planta, resistencia a diferentes factores bióticos y abióticos, rendimiento y calidad de fruto, pero su producción y aprovechamiento es local. La producción comercial del jitomate se basa en híbridos patentados tipo saladette, bola y cherry, lo que limita la expresión del acervo genético en el país. No obstante, México es considerado uno de los centros de domesticación de este producto hortícola. El objetivo del estudio fue comparar características agronómicas relacionadas con el desarrollo de las plántulas de 13 poblaciones nativas de jitomate con dos híbridos comerciales e identificar aquellas con la calidad de plántula... |

| 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... |

| The objective of this work was to study the density of trichomes and hydrocarbons associated with the resistance by antixenosis of 42 subsamples of tomato plants from the Horticultural Germplasm Bank of the Universidade Federal de Viçosa (HGB-UFV) to Liriomyza trifolii. These subsamples were studied in addition to 'Santa Clara' cultivar, which was used as a standard of susceptibility to leafminers. The evaluated characteristics were the number of mined leaflets per plant, mines per plant, trichome density and chemical compounds in the leaves. Differences were detected among the subsamples in the variables studied. We identified 20 peaks in the chromatograms of leaf hexane extract the subsamples tested. The subsamples HGBs - 216, 813, 985, 987, 991, 992,... |

| Abstract: This work aimed to study the inheritance of resistance to Phytophthora infestans in tomato plants, using the maximum likelihood estimation function. The susceptible cultivar Santa Clara (Solanum lycopersicum) was used as the female genitor and the P. infestans resistant S. habrochaites f. glabratum accession (BGH 6902) as the male genitor. F1 plants from the crossing were self-pollinated to produce F2 progenies, and also backcrossed with PR and PS to produce BC1:R and BC1:S generations, respectively. The tomato plants were inoculated 50 days after transplanting. Disease severity was evaluated via a diagrammatic scale. Comparison of the genetic models created using the maximum likelihood function revealed that the inheritance of resistance to P.... |

| Um Tymovirus isolado de sementes de tomateiro (Solanum lycopersicum) 'Paronset' com sintomas de necrose, denominado TyToRS08, foi caracterizado quanto ao círculo de hospedeiras, propriedades físico-químicas, sorológicas e moleculares. O vírus foi transmitido mecanicamente a partir de folhas, frutos e sementes infectadas. A gama de hospedeiras incluiu espécies de Amaranthaceae, Chenopodiaceae e Solanaceae, induzindo sintomas local e sistêmicos na maior parte das espécies, exceto para Nicotiana sylvestris, N. tabacum 'Samsun', 'White Burley' e 'Xanthi' que não manifestaram sintomas. Em tomateiros 'Alambra', 'Thomas', 'Diva', 'Romana' e 'Graziela', o vírus induziu sintomas de mosaico e necrose branca. A presença do vírus foi detectada, nas sementes infectadas... |
