Resumo: The study aimed to evaluate the effect of irrigation suppression by flood in different reproductive stages on rice seed quality of the cultivars BRS Atalanta, Querencia BRS and BRS 7 Taim. The irrigation suppression was performed in different reproductive stages: exertion panicle (R3), milk grain (R6), grain pasty (R7) and full maturity (R9). The seed quality was evaluated by germination test, cold test, accelerated aging, electrical conductivity and health seeds. The experimental design was completely randomized with five replications. The data were submitted to variance analysis. The means were compared by Tukey test at 5% probability. In the climatic conditions in which was conducted the experiment, it was not possible to check the effect of irrigation suppression on seed quality of the rice cultivars BRS Atalanta, BRS Querencia and BRS Taim. The climatic conditions contributed to the maintenance of water blade in rice crop until close to harvest.

A pesquisa teve como objetivo avaliar o efeito da supressão da irrigação por inundação em diferentes estádios reprodutivos na qualidade das sementes de arroz das cultivares BRS Atalanta, BRS Querência e BRS 7 Taim. A supressão da irrigação foi realizada em quatro estádios reprodutivos distintos: exerção da panícula (R3), grão leitoso (R6), grão pastoso (R7) e maturidade completa (R9). A qualidade das sementes foi avaliada pelos testes de germinação, frio, envelhecimento acelerado, condutividade elétrica e sanidade. O delineamento experimental foi inteiramente casualizado com cinco repetições. Os dados obtidos foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 5% de probabilidade. Para as condições edafoclimáticas em que foi realizado o experimento, não se verificou o efeito da supressão da irrigação na qualidade de sementes das cultivares de arroz irrigado BRS Atalanta, BRS Querência e BRS Taim. As condições climáticas contribuíram para a manutenção da lâmina de água na lavoura até próximo à colheita. Departamento de Diagnóstico e Pesquisa Agropecuária.
