| Outline of Final Research Achievements |
The patterns in seed and pollen dispersal were estimated using the genetic analysis for two dipterocarp species with different number of large wings. Contrary to the expectations from morphological traits, mean seed dispersal distance of species with three large wings was not larger than that of one with two large wings. Although the maximum pollen dispersal distance was similar in the two dipterocarp species, the frequency of pollen dispersal at a given distance differed between species. 21.5～26.7% of dipterocarp seedlings survived for about four years. Mortality and growth rate were not affected by neither seed nor pollen dispersal distances in seedlings of both dipterocarps, whereas the positive effect of predator satiation was indicated for the survival of dipterocarp seedlings.
