| Outline of Final Research Achievements |
Branching strategy for the pollination of Alpinia zerumbet (Zingiberaceae) in Okinawajima and Minamidaito islands of the Ryukyus was verified by investigating flowering phenology, nectar secretion pattern and pollinator fauna characteristics. The results indicated that 1) In addition to daily peaks in nectar secretion, A. zerumbet secreted relatively larger volume of nectar with low sugar concentrations in the evening,２）as well as diurnal pollinator such as bees, nocturnal hawk moth species also contributed to pollination of A. zerumbet in the evening, 3) linalool was one of the major components of floral scent in A. zerumbet and may act as attractant for hawk moth species.
