| 英文摘要 | Net photosynthetic rate (p-n) of leaves grown under free-air co2 enriched condition (face, about 200 mu mol mol(-1) above ambient air) was significantly lower than p-n of leaves grown at ambient co2 concentration (ac) when measured at co2 concentration of 580 mu mol mol(-1). this difference was found in rice plants grown at normal nitrogen supply (25 gin; nn-plants) but not in plants grown at low nitrogen supply (15 g m(-2); ln-plants). namely, photosynthetic acclimation to face was observed in nn-plants but not in ln-plants. different from the above results measured in a period of continuous sunny days, such photosynthetic acclimation occurred in nn-plants, however, it was also observed in ln-plants when p-n was measured before noon of the first sunny day after rain. hence strong competition for the assimilatory power between nitrogen (n) and carbon (c) assimilations induced by an excessive n supply may lead to the photosynthetic acclimation to face in nn-plants. the hypothesis is supported by the following facts: face induced significant decrease in both apparent photosynthetic quantum yield (phi(c)) and ribulose-1,5-bisphosphate (rubp) content in nn-plants but not in ln-plants. |
