| 英文摘要 | Atmospheric CO2 concentration ([CO2]) has increased by 49% since the pre-industrial era, and this increase will continue. Photosynthesis has long been recognized as one of the most temperature-sensitive processes, while far less is known about how elevated [CO2] (e[CO2]) affect crop photosynthesis response to short-term temperature increase. To reveal the effect, we measured gas exchange of winter wheat and rice with various leaf temperatures (T-L) under different [CO2] conditions (ambient, +120 mu mol mol(-1) in wheat, +160 mu mol mol(-1) in rice, and +200 mu mol mol(-1) in both) using open-top chamber facility. Analysis of the measurements showed that e[CO2] generally increased net photosynthesis (P-n) by 10-40% across various T-L at different developmental stages. The temperature sensitivity of P-n was negatively correlated with T-L. Elevated [CO2] raised the temperature optimum (T-opt) of P-n by 1.8-5.6 degrees C for wheat and 2.2-4.8 degrees C for rice, resulting in a wider range of T-L that can promote P-n. The responses of stomatal conductance, the maximum rate of carboxylation and the ratio of intercellular to growth environment [CO2] to T-opt are not only crop-specific but also stage-dependent. Furthermore, there is a divergence in the relationships between photosynthetic parameters for wheat and rice at T-opt. We conclude that e[CO2] raises T-opt of leaf photosynthesis and thus promotes P-n of winter wheat and rice in a humid subtropical climate. Further research on the coordination of leaf hydraulic and photosynthetic parameters in upland wheat and irrigated rice, as well as their response to e[CO2] should be made in the context of climate change. |
