There is controversy about the benefits of silicon (Si) on tomato plants. This element has structural and metabolic functions in the physiology of plants, generating benefits that may result in increased productivity of various plant species. Thus, the aim of this study was to evaluate the phytotechnical characteristics and the productivity of tomato plants according to the rates and sources of Si. The design was established in randomized blocks with factorial 3x5, corresponding to three sources of silicate (calcium silicate, potassium silicate and sodium silicate) and five doses of Si (equivalent to 0, 100, 200, 400 and 800 kg ha-1 of SiO2). The fertilization with Si increased the commercial productivity of tomato plants and reduced the occurrence of... |

Environmental stress, such as drought stress, constantly cause production loss. Breeding programs search for genotypes which may overcome climate adversities, producing in ideal as well as in stressful environments. The present work aimed at to evaluate parameters related to water deficit in 20 F3RC1 families of tomato plants derived from the crossing with a (WELL) genotype, originated from a drought resistant species, as well as select plants using characters related to water deficit resistance. The delineation was in randomized blocks design with three replications. Two experiments were carried out, the first in Lavras, Minas Gerais state, Brazil, that consisted in evaluating nine F3RC1 families derived from two self-fertilizations of the following... |

A caracterização dos genótipos pertencentes aos bancos de germoplasma é de suma importância pela possibilidade de identificação de genes de interesse para o melhoramento genético vegetal. Foram avaliados 64 genótipos de minitomate do Banco de Germoplasma da Universidade Estadual do Centro-Oeste, em Guarapuava-PR. O delineamento experimental consistiu de blocos casualisados com três repetições e quatro plantas por parcela. Dez genótipos se destacaram quanto à produtividade equivalente à da cultivar Sweet Grape. A maior parte dos genótipos possui frutos com formato oblongo, diâmetro médio de 25-30 mm, semelhante ao observado na cultivar Sweet Grape. Três genótipos se destacaram quanto ao teor de sólidos solúveis, com 7,37°Brix (IAC1498-63), 7,17°Brix... |

ABSTRACT This study aimed to investigate the effect of silicon (Si) sources and doses on the physicochemical quality as well as post-harvest conservation of tomato fruits. Treatments were arranged in a 3 x 5 factorial scheme corresponding to sources {calcium silicate, potassium silicate and sodium silicate} and five doses of Si (equivalent to 0, 100, 200, 400 and 800 kg/ha SiO2). Randomized blocks were the experimental design, with four replications. Soluble solids, vitamin C, lycopene, titratable acidity, mature fruit firmness, initial firmness, firmness half-life, time until reaching firmness equivalent to 3.0 x 104 N/m2 and 2.0 x 104 N/m2 and Si content in fruits were evaluated. Soluble solids, vitamin C and lycopene of fruits increased with increasing... |
