Resumo: | High temperature reduces grain yield of common bean (Phaseolus vulgaris L.) as a consequence of the abortion of reproductive structures. Heat stress was applied in common bean cultivars BRS Pérola and BRS Valente, in different phenological stages to verify grain yield reduction. Plants were grown in pots at 22C/18C day/night, 12/12 hours, without water and nutrients limitations and with preventive insect and disease control. At stages V4, R5, R7, and R8 plants were submitted to temperatures of 37C/25C day/night, 12/12 hours for 72 hours, in growth chamber and then returned to the initial conditions. Pod abortion was evaluated, and, at R9 stage, accumulated dry weight and yield components were evaluated. Heat stress applied at R5, R7 and R8 stage increased the number of pods per plant; however, grains per pod and dry weight per seed decreased. From the data obtained it can be concluded that incidence of high temperatures from R5 until R7 stages reduced grain yield and commercial grain quality of common beans. KEY-WORDS: Phaseolus vulgaris; pod abortion; biomass yield; temperature. |

KEY-WORDS: Phaseolus vulgaris; pod abortion; biomass yield; temperature. Altas temperaturas podem reduzir o rendimento de grãos do feijoeiro comum (Phaseolus vulgaris L.) cultivado em regiões tropicais, em decorrência do abortamento de estruturas reprodutivas. Para determinar o período fenológico em que a incidência de altas temperaturas acarreta maior redução no rendimento, foram aplicados estresses térmicos em diferentes estágios fenológicos de plantas de feijoeiro, das cultivares BRS Pérola e BRS Valente. As plantas foram cultivadas em vasos, sem limitação de água e nutrientes e com controle fitossanitário preventivo, em temperaturas de 22oC/18oC dia/noite, 12/12 horas. Nos estágios V4, R5, R7 e R8, as plantas foram submetidas a temperaturas de 37oC/25oC dia/noite, 12/12 horas, durante 72 horas, em câmara de crescimento, após o que foram reconduzidas às condições anteriores. Avaliaram-se as vagens abortadas, e no estágio R9, o acúmulo de biomassa seca e os componentes do rendimento. O estresse térmico aplicado nos estágios R5, R7 e R8 aumentou o número de vagens por planta, vagens estas com menor número e massa de matéria seca nos grãos. Conclui-se que a incidência de altas temperaturas nos estágios R5 até R7 ocasionou redução sensível na produtividade e na qualidade dos grãos do feijoeiro comum.
