Biologia da polinização de Jacaratia spinosa (AUBL) ADC. (CARICACEAE) em mata residual do sudeste brasileiro

摘要: The pollination biology of Jacaratia spinosa (Aubl) ADC. (Caricaceae) was studied in Mata de Santa Genebra, Campinas municipality, Sao Paulo state, Brazil (20o54'S; 47o05'W). Data from floral anthesis, nectar volume and sugar concentration, pollen viability, stigma receptivity, location scent glands, reproduction systems main visitors/potential pollinators were obtained. species is dioicious the masculine plants flourish for a larger period (52 days) than feminine ones (22 days). Most flowers has night lasting about 24 hours ones, 48 hours. produce on average, 112,5 ml concentration 13,9%. didn't nectar, having been identified mimetism by ones. viability vary along day (average 97,20%). There production fruits agamospermy crossed fecundation. observed moths, what corroborates with its characteristics phalenophily syndrome; other insects meantime, as butterflies, also can contribute to reproduction.
