Text of abstract in plants, stress caused by water deficiency is a major problem in agriculture. Therefore, it is necessary to seek alternatives that aim to maximize yielding with minimal water use and no economic loss. Thus, the objective of the present study was to assess the physiological quality of corn seeds produced under different conditions as to amount of water in the soil. Five soil moisture points were determined, based on field capacity (100, 85, 70, 55 and 40%), providing controlled water conditions to two corn hybrids (BRS 1040 and DKB 390). The experimental design consisted of randomized blocks in a split-plot arrangement with four repetitions; water replacement was applied to the plots, and the hybrids, to the subplots. After the seeds were harvested, water content, germination and vigor were determined (seedling emergence, first germination count, germination speed index, accelerated aging, and electrical conductivity). Seeds produced by hybrid DKB 390 expressed better physiological potential. Irrigation depths to keep soil moisture between 75.18 and 94.04% of the field capacity favor the physiological quality of the seeds produced.

“…carbonados que foram destinados a formarem as reservas das sementes (Vieira et al 2013), e a insuficiência e/ou ausência de alguma dessas reservas diminuiu a germinação e o vigor das sementes produzidas. Vale ressaltar que a ocorrência de deficiência hídrica durante o período de transferência de matéria seca pode provocar redução no peso das sementes e afetar de forma significativa o seu desempenho (Peres et al 2018).…”

A qualidade fisiológica das sementes é um aspecto de grande relevância para o estabelecimento de uma cultura. No entanto, as condições de manejo das plantas durante a produção de sementes podem influenciar na sua qualidade. Diante do exposto, objetivou-se avaliar a qualidade fisiológica de sementes de crambe oriundas de plantas submetidas a diferentes regimes hídricos. O delineamento experimental utilizado foi em blocos casualizados, composto por cinco condições de água no solo, baseadas na capacidade de campo (100, 85, 70, 55 e 40%) que consistiram nos tratamentos, com quatro repetições. Após a colheita, as sementes foram encaminhadas ao laboratório de sementes, beneficiadas e em seguida, avaliadas quanto ao teor de água, germinação e vigor. Plantas de crambe cultivadas em condições de água no solo entre 59 a 61% da capacidade de campo produzem sementes de melhor qualidade fisiológica, demonstrado pelo desempenho nos testes de germinação e vigor.
