RESUMOO presente trabalho teve como objetivo estudar a fenologia da espécie arbórea Astronium graveolens Jacq. e correlacioná-la com a precipitação, umidade relativa e temperatura da região de estudo. Os estudos foram conduzidos em um fragmento de floresta estacional decidual, no campus da Universidade Estadual do Sudoeste da Bahia em Vitória da Conquista, Bahia, Brasil. Os indivíduos foram visitados quinzenalmente de setembro de 2010 a dezembro de 2014, quando foram registradas as características fenológicas referentes a desfolhamento, brotamento, floração e frutificação. A análise dos dados fenológicos foi feita através de testes de normalidade, utilização de estatística circular para testar a sazonalidade das fenofases e teste de correlação de postos de Spearman, para verificar com qual intensidade e sentido os eventos climáticos se relacionavam com as fenofases. A espécie apresentou uma queda foliar com padrão decíduo de alta sincronia com concentração no período de seca, seguido pelo brotamento altamente sincrônico que se iniciou no começo da estação úmida. A floração e frutificação apresentaram um padrão bianual, sendo um evento que se manifestou como sendo de baixa sincronia a assincrônico. Palavras-chave: sincronia; fenofase; clima. ABSTRACTThis current study had the objective to study the phenology of tree species Astronium graveolens Jacq. and correlates it with precipitation, relative humidity and temperature of the study area. The studies were conducted in a fragment of the deciduous forest in the campus of the State University of Southwest Bahia in Vitória da Conquista, Bahia state, Brazil. The subjects were visited fortnightly from September 2010 to December 2014, when the phenological characteristics related to senescence, budding, flowering and fruiting were recorded. Data analysis done through normality tests, utilization of circular statistics to test the seasonality of phenophases and correlation test of Spearman's rank to check with which intensity and direction the climatic events were related to the phenophases. The species presented a foliar fall with deciduous pattern of high synchrony with concentration in the dry season, followed by budding highly synchronic that began in the early wet season. The flowering and fruiting presented a biennial pattern, being an event that was manifested as low sync at the asynchronous.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
