| Outline of Final Research Achievements |
We have demonstrated the acclimating mechanisms of dwarf bamboo, Sasa kurilensis, to the different light conditions in the understory of a beech forest. Density and biomass of S. kurilensis were significantly largest under the gap, and smallest under the canopy trees of Fagus crenata. Maximum photosynthetic rate per a culm was estimated from the photosynthetic rate per a unit leaf area, leaf areas, and leaf numbers of a culm. The values were lowest under the canopy trees of F. crenata, and significant differences were not detected between the values under the gap and the canopy trees of Magnolia obovata. S. kurlensis dominates the understory in a beech forest by the acclimatization in the different light conditions caused by different canopy types.
