| Research Abstract |
The role of defense system of tree seedlings was studied in relation to decisive factor of initial survival in the natural regeneration of Fagus crenata. Seedling survival rate and the concentrations of antifungal substances were higher under the higher light conditions than that under lower light conditions. This result indicates that progress of defense system in seedlings is one of the decisive factors of initial survival of the seedlings.
