光合作用是生物界最基本的物质代谢和能量代谢,分为光反应和暗反应两个阶段。光合作用速率是表征光合作用快慢的物理量,通常以单位时间单位叶面积上吸收的CO2的物质量表示,受光照(光照时间、光强度、光质)、CO2浓度、温度、水、必需矿质元素等环境因素的综合影响。用图像定性或定量地反映各
Photosynthesis is the most basic material metabolism and energy metabolism in the biosphere. It is divided into two stages: light reaction and dark reaction. The rate of photosynthesis is the physical quantity that represents the speed of photosynthesis. It is usually expressed as the amount of CO2 absorbed in the leaf area per unit of time. It is affected by light (light time, light intensity, light quality), CO2 concentration, temperature, water, and essential mineral elements. The combined effects of other environmental factors.
