Biologia floral e sistema de polinização de Solanum stramonifolium Jacq. (Solanaceae) em remanescente de Mata Atlântica, Pernambuco

摘要: The anthers deiscense through two small apical pores is a feature found in many species of Solanaceae, especially the genus Solanum. This restricts pollination to group female bees which are able vibrate (buzz pollination). phenology, floral biology and Solanum stramonifolium were studied between August/1999 December/2000 natural populations occurring at Dois Irmaos State Park, one last Atlantic forest remnants Recife city, Pernambuco state (8°7'30"S 34°52'30"W). shrub whose flowers arranged racemose inflorescence have white corolla five stamens with poricide disposed around gynoecium. Anthesis occur early morning petals present ultraviolet reflection pattern. presents continuous flowering pattern hermaphrodite (62%) functional male (38%), therefore andromonoicious. Thirteen observed visiting S. (nine pollinators four pollen robbers). great constant production along year important maintain guild guarantee plant reproduction.
