The atmospheric concentration of CO2 is exceeding 400 ppm (V/V) in recent years. The global warming by increasing CO2 concentration affects on ecosystems negatively. Our objective in this study is to clarify characteristics of leaves and their photosynthetic responses to increasing CO2 concentration...
