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.

对京都大学上贺茂实验林万年青与落叶共存树种当年生枝条的叶、茎性状进行了研究。叶寿命较长，叶光合能力较小，万年青比落叶树种，在各种以前的研究。与此相反，屈曲安全系数是落叶比万年青树种。然而，这种差异消失时，极端拍摄形态的物种被删除。这些结果表明，叶和茎的性状受不同因素的影响。
