| 摘 要： | 光呼吸是C3植物体内重要的代谢过程.本文阐述了人类经济发展的同时对自然环境所产生的种种影响后果,包括CO:浓度升高、紫外辐射增加、温度变化、强光等环境因子对植物光呼吸所产生的影响,如直接或间接导致植物光呼吸速率的变化,进而在植物生理和生态上产生相关的效应.C3植物在受到环境胁迫时,可以通过光呼吸协调代谢功能,在一定程度上发挥规避环境、尤其是极端环境胁迫的效应.因此,可通过调节C3植物的光呼吸规避环境胁迫,这为光呼吸研究在环境生态学领域的拓展指出新的方向.

| Abstract: | Photorespiration is an important metabolic process in C3 plants. This article analyzes the effects of human and economic development like increased CO2 emission, ultraviolet radiation, temperature, light, etc., which influence photorespiration such as directly or indirectly changing photorespiration rate that can lead to secondary effects on plant physiological and ecological development. When C3 plants are under environmental stress, photorespiration corresponds to metabolism which eludes the stress, especially when the environmental stress is severe. Hence photorespiration of C3 plants under environmental stress leads to a new direction of research in environmental ecology and photorespiration. |
