| Research Abstract |
The traits of leaves and stems of current-year shoots were investigated for coexisting evergreen and deciduous tree species in Kamigamo Experimental Forest, Kyoto University. Leaf lifespan was longer and leaf photosynthetic capacity was smaller in evergreen than in deciduous species, as in various previous studies. In contrast, buckling safety factor was greater in deciduous than in evergreen species. This difference was, however, disappeared when the species with extreme shoot morphologies were removed. These results suggest that the traits of leaves and stems are influenced by different factors.
