| Outline of Final Research Achievements |
For effective plant production based on environmental control in greenhouses, fundamental studies on evaluating and controlling absorption processes of carbon (C) and nitrogen (N) by plant and following transport processes of them in plant body were conducted. Long-term effect of CO2 enrichment on canopy photosynthetic rate was evaluated on the basis of CO2 balance in greenhouse-scale. CO2 enrichment also enhanced flux of sugar as photoassimilate into sweet pepper fruit in afternoon. Furthermore, characteristics of root absorption function and following allocation of nitrogen in plant organs affected by CO2 enrichment was revealed quantitatively. Thus, fundamental information on absorption of carbon and nitrogen by plants and following transport of them in plant body in response to environment was obtained in greenhouse with controlled environment.
