大气CO2浓度和温度升高对C3作物光合作用影响的生理机制
Effects of elevated atmospheric CO2 concentration and temperature on photosynthetic physiological mechanisms in C3 crops
摘要
Abstract
Climate change,characterized by elevated atmospheric CO2 concentration and rising temperature,has become a globally focused issue that has significantly impacted crop production.Photosynthesis serves as the foundation of crop yield formation,while CO2 is the substrate for photosynthesis.The increased atmospheric CO2 concentration can promote the photosynthesis of C3 crops,while increased air temperature generally constrains crop photosynthetic ability.However,the combined effects of elevated atmospheric CO2 concentration and temperature on the crop photosynthetic mechanisms remain unclear.Focusing on the separate and interactive effects of elevated atmospheric CO2 concentration and temperature,this review analyzes the changes of photosynthetic rate,chlorophyll content and stomatal conductance,as well as the phenomenon of"photosynthetic acclimation"in various crops,particularly C3 crops.Considering regional differences in climate change,it explores the photosynthetic physiological mechanisms under concurrent elevated CO2 concentration and temperature,with the aim of providing theoretical support for enhancing the photo-synthetic capacity and ultimate productivity of C3 crops under climate change conditions.关键词
