研究了山毛榉（Fagus crenata）幼苗的补充和存活，并对林下竹（Sasa kurilensis）的同时死亡进行了研究。山毛榉幼苗在萨沙已经枯萎的地板上的成活率远远高于萨沙存活的地板。在山毛榉幼苗中，猝倒引起的死亡率最高。但物质在苗木不同部位的分配格局表明，苗木成活受生产经济的影响较大。矮竹的密集覆盖阻碍了床苗库的建立。同时死亡的时间间隔和恢复期的长短是控制日本山毛榉林动态的重要因素。
Seedling recruitment and survivorship of beech (Fagus crenata) were studied with special reference to the simultaneous death of undergrowing bamboo (Sasa kurilensis). The survival rate of beech seedlings on the floor where Sasa had withered was much higher than that on the floor where Sasa survived. Damping off caused the largest mortality among beech seedlings. However, the allocation pattern of matter to different parts of the seedlings indicated that their survival was greatly affected by production economy. The dense cover of dwarf bamboo prevented the establisment of bedch seedling banks on the forest floor. The interval between the times when simultaneous death of Sasa occur and the length of its recovery period are thus important factors controlling the dynamics of beech forests in Japan.
