Outline of Final Research Achievements

We have investigated mating system and gene flow of dipterocarp species for multiple flowering year, which are forestry and ecologically important tree species in Southeast Asia. Among various dipterocarp species, we have studies Shorea acuminata, S. macroptera and so on. We have estimated the breeding unit size using the obtained data such as gene flow and mating system. Mostly Shorea species required 100 ha for breeding unit. To maintain high genetic diversity of tropical forest and conduct sustainable selective logging in this region, at least 100 ha of multiple forests should be maintained for each species.
