| Research Abstract |
In order to clarify the ecological role of seed chemical compositions of oaks Quercus spp., the content of chemicals(major nutrients and tannins) in seeds were analyzed for 10 species of Japanese oaks. As a result, notable inter-and intraspecific variations in chemical compositions were found even among closely related species. Further, a trade-off was recognized between the contents of nonstructural carbohydrates and tannins. In addition, it was proved that seed traits had substantial influences on seed fates and thereby the reproductive success of the mother trees via interactions with seed consumers.
