| Research Abstract |
The objective of this research was to clarify the accommodation of dwarf bamboo communities growing in the secondary forests to light environments, for the purpose of creation and conservation of Satoyama forests. Several experiments were conducted to examine the eco-physiological characteristics of Pleioblastus pubescence under different light conditions. The results showed that photosynthesis rates of leaves are higher but longevities of culms, branches, and leaves are shorter in the light conditions than in the dark conditions. Individuals in the light conditions are under excess light stress and increase the pool size of heat dissipation pigments in the leaves for the protection from that stress. The results suggested that P.pubescence maintains productivities by different dynamics of culms, branches and leaves in different light conditions.
