Research Abstract

The pollination system of tropical rainforest tree Shorea acuminata during the generalflowering period was investigated by using a newly developed microsatellite DNA analysisof single pollen grains adhering to pollinators. The genetic analysis of pollen grainssuggested that predators of thrips contributed to the long-distance cross-pollination of S. acuminata trees. Thus, it was considered that such ecological food chain provided sufficientpollination service for S. acuminata during the general flowering period.
