摘要：

【目的】探讨大气CO₂浓度升高与增温影响下北方冬小麦叶片光合特征、碳氮代谢物、生物量和产量形成的调节适应规律,为未来气候变化下小麦生产提供理论依据。【方法】以冬小麦品种“中科2011”为材料,利用封闭式人工气候室,设置对照CK（CO₂浓度和气温与大田一致）、EC（CO₂浓度为大田浓度+200 μmol·mol^-1,气温与大田相同）、ET（CO₂浓度与大田一致,气温为大田温度+2℃）、ECT（CO₂浓度为大田浓度+200 μmol·mol^-1,气温为大田温度+2℃）共4个处理。测定CO₂浓度升高200 μmol·mol^-1和气温升高2℃变化条件下冬小麦生长发育、叶片的光合特性、碳氮代谢、生物量和产量指标。【结果】气温升高2℃会缩短小麦全生育期及开花到成熟时间,使孕穗期净光合速率显著增加24.7%,而对拔节期与灌浆期净光合速率无显著影响,同时,使灌浆期叶片纤维素含量、可溶性蛋白含量和硝酸还原酶活性下降,穗粒数和千粒重下降,进而使产量与生物量分别显著降低23.0%和19.7%;CO₂浓度升高200 μmol·mol^-1使拔节期与孕穗期小麦净光合速率分别提高32.8%和40.7%,增加灌浆期叶片碳水化合物含量,虽然生长后期出现光适应,但仍可通过增加单位面积穗数使小麦产量增加26.1%。在增温条件下,CO₂浓度升高可通过使开花到成熟的时间延长2 d、叶片净光合速率提高约25.54%、增加可溶性总糖、纤维素与淀粉含量等弥补升温对小麦生物量和产量的负效应。【结论】CO₂浓度升高可通过延长开花到成熟时间、提高小麦净光合速率、增加光合代谢物等弥补升温对小麦生物量和产量的负效应。

Abstract:

【Objective】This study was conducted to clarify the response and acclimation process of winter wheat under elevated carbon dioxide (CO₂) concentration and rising temperature in North China, so as to provide the theory basis for wheat production under future climate change condition.【Method】Winter wheat (Triticum aestivum ‘Zhongke2011’) plants were subjected to elevated CO₂ concentration (ambient concentration +200 μmol·mol^-1) and rising temperature (ambient temperature +2℃) at open top climate chambers. The photosynthetic traits, carbon and nitrogen metabolism, biomass accumulation and yield formation of winter wheat in response to elevated CO₂ concentration and rising temperature were investigated. 【Result】The rising temperature shorten the whole growth period and the time from florescence to harvest of this wheat cultivar. The net photosynthesis rate (P_n) was enhanced at booting stage by 24.7%, but was not obviously changed in elongation and filling stages. However, the leaf fiber content, soluble protein content and nitrate reductase activity in filling stage, and kernels per spike, thousand seed weight, biomass, and yield in harvest stage decreased by 23.0%. Elevated CO₂ concentration increased P_n in the elongation and booting stage by 32.8% and 40.7%, respectively. Elevated CO₂ concentration also increased leaf carbohydrate content in the filling stage and spike number per unit area, and improved yield by 26.1%, although which induced photosynthesis acclimation at the late growth stage. Moreover, elevated CO₂ concentration increased the time from florescence to harvest of wheat plants for 2 days, and improved P_nby 25.54%, leaf soluble sugar content, fiber content, and starch content under rising temperature conditions. 【Conclusion】Elevated CO₂ concentration could offset the negative impacts of rising temperature on biomass accumulation and yield of wheat plants by increasing the time from florescence to harvest, net photosynthesis rate and carbon metabolism.
