Resumo

The anthesis, anther dehiscence, pistil receptivity, pollen tube growth and fruit set of Capsicum frutescens L. (Solanaceae) were studied in São Miguel do Anta, Minas Gerais State, southeastern Brazil. C. frutescens flowers are perfect, protogynous and receive visits from many bee species, mainly Apis mellifera L., which collect pollen and nectar. Treatments of pollination by bees, hand cross pollination, open pollination, emasculated open pollination and spontaneous self pollination were performed. Pollen tube growth pattern did not differ among treatments. Pollen tubes were observed in the ovary within 24 hours after pollination. Despite C. frutescens being considered autogamous, this crop benefits from pollination by A. mellifera, producing better fruit set than by using spontaneous self-pollination.
