Resumo: | This work was accomplished with the objective of evaluating the influence of the sowing date on the physiological seed quality of five soybean cultivars, Glycine max (L.) Merril (Leguminosae-Faboideae), and also to establish the best sowing period to produce seeds with better quality. Were conducted five cultivars assay in the agricultural year of 1999/00, in randomized blocks design. Each assay was sowed in different dates (15/10, 30/10, 15/11, 30/11 and 15/12). The evaluated cultivars were: BRS 132, BRS 133, BR 16, BRS 134 and FT- Estrela. The seeds obtained were evaluated, by the germination test (first and final count), classification of seedling vigor and accelerated aging. The sowing realized in the period between november three and 20, depending on the cultivar, went more favorable to obtain seeds with hightest physiological quality. BRS 133 presented the greatest stability in the seed production with better quality in the different evaluated sowing dates. Generally the BR 16 cultivar presented inferior performance and BRS 133 the superior performance |

Merril (Leguminosae-Faboideae), bem como estabelecer o intervalo de semeadura mais favorável à produção de sementes de alta qualidade na região de Maringá, Estado do Paraná. Foram conduzidos cinco ensaios de competição de cultivares no ano agrícola de 1999/00, utilizando-se o delineamento experimental em blocos casualizados. Instalou-se um ensaio em cada época de semeadura (15/10, 30/10, 15/11, 30/11 e 15/12). Os cultivares avaliados foram: BRS 132, BRS 133, BR 16, BRS 134 e FT-Estrela. As sementes produzidas foram avaliadas pelo teste de germinação (primeira contagem e contagem final), classificação do vigor de plântulas e envelhecimento acelerado. Constatou-se que a semeadura realizada entre 3 a 20 de novembro, dependendo do cultivar, foi mais favorável a obtenção de sementes de melhor qualidade fisiológica. O cultivar BRS 133 apresentou maior estabilidade na produção de sementes com melhor qualidade nas diferentes épocas de semeadura avaliadas. De modo geral, em relação aos demais cultivares, o BR 16 apresentou desempenho inferior e o BRS 133 superiorUniversidade Estadual de Maringá2008-04-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/229110.4025/actasciagron.v24i0.2291Acta Scientiarum.
