Fenologia reprodutiva e biologia da polinização de Canavalia brasiliensis Mart. ex Benth (Fabaceae)

Reproductive phenology and pollination biology of Canavalia brasiliensis Mart. ex Benth (Fabaceae). This work studied the phenology and biology of the pollination of C. brasiliensis in an area of its natural occurrence (Pocinhos – PB). Fifteen plants were marked and observed every two weeks for the study of phenology. For the study of floral biology and morphology, flowers and inflorescences were marked and observed until fruit appeared. Visitors to flowers were observed throughout the experiment, and the frequency, time and behavior of their visits was registered. Canavalia brasiliensis demonstrated a pattern of annual flowering which was continuous, of long duration, with periods of greater flowering activity in the dry season. The inflorescence is of the paniculatum type, with flowers whose attributes are related to the syndrome of melittophily. Anthesis occurs
