Outline of Final Research Achievements |
In this study, we aim to clarify a mechanism that tropical tree species adopts soil environment of their own habitat. Five Macaranga and 8 Shorea species were chosen in Pasoh Forest Reserve of Malaysia, and the environmental factors of their habitat and their fine root morphology were measured. As a result, tree species grow in different environment of soil water and light. However, the difference in soil nutrient condition among tree species was detected for Macaranga but not for Shorea. The difference in fine root diameter among tree species was detected for Macaranga. These results indicate a possibility that fine root morphology is related to light condition rather than soil condition.
