| Outline of Final Research Achievements |
Whole-plant physiology is one of the most applicable research fields for linking from leaves to ecosystems, providing us the mechanistic insight into evaluating the effects by global environmental changes. However, whole-plant physiological ecology including roots has been very limited. In the present study, we evaluated the individual respiration, photosynthesis, and water use using yang trees growing under various light environments in forest ecosystems with custom made chambers.
Although many studies have generally pointed that the shading causes a carbon deficit at an individual level as results of competition over light acquisition, the ratio in potential of photosynthesis (under saturated light) to respiration at individual levels did not show a clear difference among shaded and dominant individuals. Actually, we did not find declining trees by shading in the study sites. Additionally, we observed the lower water use efficiency in the smaller sized trees.
