| Outline of Final Research Achievements |
This study investigates effects of environmental conditions on net photosynthesis by using artificially controlled environment. This study discussed about the CO2-exchange rates of aseptic-medium-cultured plants, Arabidopsis thaliana, which were observed under the conditions of elevated ambient pressures from 0.1 MPa to 0.3 MPa. Results show that, while the net photosynthetic rate was increased, the rate of dark respiration fluctuated little under the elevated ambient pressures. It can be thought that these results come from the competitive reaction of the photosynthesis. Those are promotion of the photosynthesis by increasing CO2 partial pressure and the suppression of the photosynthesis by increasing O2 partial pressure.
