| Research Abstract |
Physiological and morphological responses to canopy gap for tree species commonly found in Japanese satoyama forests were studied. High stem diameter growth was significantly related to high plasticity in leaf morphological and structural traits such as intercellular space, palisade mesophyll layer thickness, leaf area, and leaf weight per unit leaf area. These results suggest that greater leaf-level phenotypic plasticity between shade and gap is critical to the growth and long-term survival of forest tree species in the fluctuating light environment of the satoyama forest.
