| Research Abstract |
Light environments, photosynthetic characteristics, leaf morphological characteristics and polyphenol contents were measured within a canopy of Fagus crenata. The maximum photosynthetic rate increased with the decrease in specific leaf area, and with the increase in polyphenol content. We utilized specific leaf area as an indicator for evaluation of photosynthetic characteristics. Leaf area/mass for each photosynthetic characteristic was obtained from the distribution of specific leaf area of falling leaves. We estimated canopy photosynthesis in a sunny day by using these results. The 80% of the canopy photosynthesis was due to photosynthesis by leaves which constituted 36% of total leaf area.
