Resumo: The effects of bean plant chemical desiccation on seed storage quality were evaluated in this research. Paraquat (400g a.i/ha) and paraquat + diquat (250g a.i/ha + 150g a.i/ha) were applied, at the dose of 2L/ha of c.p. at 26, 29, 33 and 36 days after flowering (DAF). During storage (70% and 10±1ºC), germination (standard test), vigor (germination speed) and fungi occurrence were evaluated at zero, 60 and 120 days. No evidence of loss in the seed quality was found after the desiccation with paraquat and paraquat + diquat. In desiccation with seed moisture content of 37-26% (29-33 DAF) the stored seed high quality was maintained

Plantas do cultivar Carioca foram dessecadas, com o uso dos herbicidas paraquat (400g i.a./ha) e a mistura paraquat + diquat (250g i.a./ha + 150g i.a./ha), ambos na dose de 2 L/ha pc. e volume de calda de 300 L/ha, aos 26, 29, 33 e 36 dias após a floração (DAF). Após a colheita, as sementes foram acondicionadas em embalagens de polietileno e armazenadas durante 120 dias em câmara fria (70% UR e 10 ± 1ºC). Avaliou-se a qualidade das sementes aos zero, 60 e 120 dias de armazenamento pelo teste de germinação (TPG), pelo índice de velocidade de emergência (IVE) e pelo método de papel de filtro ou “blotter test”. Durante o armazenamento não houve evidências de perda de qualidade da semente associada à aplicação de paraquat e mistura paraquat + diquat. A dessecação realizada quando as sementes estavam com umidade de 37-26% (29-33 DAF) contribui para a manutenção de alta qualidade da semente armazenadaUniversidade Estadual de Maringá2008-05-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/288110.4025/actasciagron.v22i0.2881Acta Scientiarum.
