| 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... |

| ABSTRACT: Problems with root-knot nematodes, caused by genus Meloidogyne, can be controlled through the introduction of resistance genes in commercial varieties of tomatoes. However, plants of the hybrid ‘Heinz 9992’ for industrial processing, carrying the Mi gene, were reported with their roots severely infected in experimental cultivation in Goiás State of Brazil with symptoms typical of galls caused by Meloidogyne spp. After dissecting the galls present in the root samples, the females of the nematodes were removed and afterwards, performed the analysis of the perineal pattern and the biochemical characterization by electrophoresis of isoenzymes, besides the pathogenicity test. The pathogen analyzed was identified as Meloidogyne incognita. The... |

| O objetivo deste trabalho foi avaliar o efeito da aplicação de Acrescent Foliar®, proveniente da fermentação alcoolica de batata, na produtividade de alface e na qualidade de mudas de tomateiro. Foram conduzidos a campo dois experimentos com a cultura da alface, em delineamento blocos ao acaso com três repetições, e dois experimentos em ambiente protegido com mudas de tomateiro, em bandejas de poliestireno expandido de 128 células, em delineamento inteiramente casualizado com quatro repetições. Foram avaliados a fitomassa fresca e a fitomassa seca da parte aérea da alface, a altura da planta, o diâmetro do caule, o número de folhas, a fitomassa fresca de raiz, a fitomassa fresca de parte aérea, a fitomassa seca de parte aérea e a relação entre a fitomassa... |

| ABSTRACT Knowledge of the combining ability of genotypes, genetic diversity, and heterosis play the paramount role in obtaining double-cross hybrids with high productivity. This study was aimed at evaluating these parameters in tomato genotypes using partial diallel crosses among the commercial single-cross hybrids, which verified the possibility of using double-cross hybrids for commercial purposes. Tomato genotypes included 15 double-cross hybrids, their genitors, and two commercial genotypes as checks. Of the fifteen double-cross hybrids of tomato, two crosses exhibited superiority, such as Aguamiel × Compack and Dominador × Compack, mainly for the total and commercial fruit yields. The phenotypic expression of the trait is controlled by the genes with... |

| A partir de 150 isolados de bactérias endofíticas obtidos de folhas, caules e raízes de tomateiros sadios, 53 destacaram-se quanto à habilidade em promover o crescimento de plantas de tomateiro (Solanum lycopersicum L.). Submetidos a uma nova seleção, os isolados UFV-E17, UFV-E22, UFV-E25, UFV-E26, UFV-E27, Bacillus cereus (UFV-E29), UFV-E49, UFLA 06-LS, UFLA 08-LS e UFLA 11-LS apresentaram maior promoção do crescimento. Avaliações semanais de altura e número de folhas e folíolos das plantas aconteceram durante 45 dias. Após a sexta avaliação, mensurou-se a área foliar e o peso da matéria fresca e seca da parte aérea e da raiz das plantas. O isolado UFV-E49 apresentou melhor resultado para altura, área foliar, número de folhas e peso da matéria fresca e... |

| We examined the resistance of improved tomato strains rich in 2-tridecanone (2-TD), zingiberene (ZGB) and acyl sugars (AA) to the tomato moth, Tuta absoluta. We also studied whether selection for strains with higher densities of glandular trichomes, and thus presumably strains with higher concentrations of 2-tridecanone, was effective in promoting greater resistance to the moth. The TOM-584 and TOM-679 strains were used as susceptible controls, which have normal concentrations of the three allelochemicals. The improved strain TOM-687, which has a high AA content, has a widely documented resistance and was used as a standard resistant strain. The wild strain PI134417, which is resistant by means of its high 2-TD content, was also used as a standard... |
