Resumo: The objective of this experiment was to evaluate responses of soybean cultivars seeds (with different levels of lignin) considering harvest postponement under the incidence of water and the effect of storage. The experiment was conducted in Iraí de Minas, Brazil using a randomized block design with three replications under a 5 x 3 x 3 factorial arrangement, with five soybean cultivars (NK 7059 RR, SYN 1163 RR, SYN 9070 RR, AS 7307 RR and SYN 1283 RR), three harvesting periods (R8, R8 + one rain simulation in the pre-harvesting period and R8 + two simulations in the pre-harvesting period) under three storage times (0, 90 and 180 days). Seeds were evaluated for their chemical composition (lignin contents), the percentage of moisture damage using the tetrazolium test and physiological quality (germination, accelerated aging, conductivity test, seedling emergence and emergence index). Cultivar AS 7307 RR had the highest lignin content in the integument, the lowest percentage of damage by moisture and the highest physiological quality. Cultivars NK 7059 RR and SYN 1163 RR had the lowest lignin contents in the integument and the highest moisture damage. Electrical conductivity increased after storing all cultivars.

O ensaio foi conduzido em Iraí de Minas, MG, em blocos casualizados com três repetições e esquema fatorial 5 x 3 x 3, sendo cinco cultivares de soja (NK 7059 RR, SYN 1163 RR, SYN 9070 RR, AS 7307 RR e SYN 1283 RR), três épocas de colheita (R8, R8 + uma simulação de chuva na pré-colheita e R8 + duas simulações de chuva na pré-colheita), e três épocas de armazenamento (0, 90 e 180 dias). As sementes foram avaliadas quanto à composição química (teor de lignina), porcentagem de danos por umidade usando o teste de tetrazólio, e a qualidade fisiológica (germinação, teste de envelhecimento, condutividade elétrica, emergência, índice de emergência). A cultivar AS 7307 RR apresentou maior teor de lignina no tegumento, menor porcentagem de danos por umidade e melhor qualidade fisiológica. As cultivares NK 7059 RR e SYN 1163 RR apresentam menores teores de lignina no tegumento e maiores danos por umidade. Os valores de condutividade elétrica aumentam com o armazenamento para todas as cultivares.Associação Brasileira de Tecnologia de Sementes2018-11-05T12:42:18Z2018-11-05T12:42:18Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCASTRO, E. de M. et al.
