          Abstract

          Em geral, espécies arbóreas que ocorrem na vegetação de Caatinga, no semiárido do Nordeste brasileiro, têm suas fenofases (floração, frutificação e mudança foliar) condicionadas pela duração e intensidade da seca sazonal. Este estudo registrou a fenologia da queda foliar, incisão, floração e frutificação em 32 indivíduos de Dalbergia cearensis. Os indivíduos foram amostrados a cada 15 dias em 2009-10 e 2010-11, na Unidade de Conservação de Uso Sustentável "Fazenda Não me Deixes", situada em Quixadá, Ceará, Semiárido brasileiro. A frequência de ocorrência das fenofases foi relacionada com os elementos do clima (precipitação pluviométrica média mensal, temperatura média mensal, insolação média mensal e disponibilidade hídrica no solo). A fenologia vegetativa, queda e brotamento de novas folhas, acompanhou a sazonalidade da precipitação pluviométrica durante as estações seca e chuvosa. A floração e frutificação ocorreram no início das chuvas, e os diásporos de D. cearensis são dispersos o ano inteiro, após se desprenderem lentamente das panículas axilares compactas.

          In general, tree species that occur in the Caatinga vegetation in the Brazilian semiarid of the northeastern region, have their phenophases (flowering, fruiting and foliage change) conditioned by the duration and intensity of seasonal drought. This study records the phenology of leaf-fall, leaf incision, flowering and fruit production of 32 Dalbergia cearensis Ducke individuals. Samples were collected every 15 days from 2009 to 2011 at the Unidade de Conservação de Uso Sustentável Fazenda Não me Deixes, a conservation area in the Brazilian semiarid. The frequency of occurrence of the phenophases was related to the elements of climate (average monthly rainfall, monthly average temperature, monthly average insolation and soil water availability). The vegetative phenology, leaf fall and sprouting of new leaves, followed the seasonality of rainfall during the dry and rainy seasons. The flowering and fruiting occurred at the beginning of the rains, and the diaspores of D. cearensis were scattered throughout the year after they broke off slowly from the compact axillary panicles.
