摘要:
CO2是植物光合作用的主要碳源。低浓度CO2能够降低植物的碳固定速率，影响植物的生长发育过程。由于C3与C4植物光合途径存在差异，所以对外界低CO2环境的应答反应不同。此外，生长环境中的其他因子如水分、温度、氮等也与低浓度CO2相互作用影响植物生长发育进程。本文从生物量及其分配、生长发育周期、气孔及光合系统，以及低CO2与其他环境因子相互作用等方面综述了低浓度CO2对植物的影响。
Atmospheric CO2 is the main carbon source for plant photosynthesis and the fundamental sub-strate for plant growth. The carbon fixation efficiency of plant is reduced and the growth and de-velopment are affected at low CO2. The effect of low CO2 on C3 and C4 plant is different because of their distinct photosynthetic pathway. Furthermore plant growth can be affected by the interactive effects of low CO2 with other environmental factors, such as water, temperature, and nutrients. In this review, the effects of low CO2 on plant growth and development are discussed in several aspects including biomass and its distribution, growth cycle, stoma, photosynthetic system and other environmental factors.
