Abstract:

The paper described the influences of the elevated concentrations of O3,reduced solar irradiance,the enhanced UV-B and the elevated CO2 concentration, and their interactions on physiological and biochemical mechanisms, such as morphological characteristics, photosynthesis,dry matter weight and crop yield.The experimental conditions of the interactions of ozone and other environmental factors were much closer to natural environment.O3 and UV-B radiation didn’t almost have positive effect on plant.The reduced solar irradiance and the elevated CO2 concentration could accelerate the growth of plant.But the reduced solar irradiance made dry matter weight and crop yield lower,and the elevated CO2 had a promoting effect on them.Under the condition of the composites with ozone, some of ozone harm to the plants could be partly alleviated.Ozone and UV-B radiation could bring greater damage to the plant.

Key words: Plant, Ozone, Solar irradiance, UV-B, CO2 concentration

Several environmental factors influence plants of the other aspects"

环境因子Environmental factors 对植物影响Impacts
O3浓度增加 影响植物的抗氧化系统,抑制呼吸作用;破坏膜系统,影响糖类、脂类、淀粉物质代谢[64,65]
太阳辐射减弱 破坏植物膜系统,降低细胞膜透性,影响植物酶活性、水分代谢和碳代谢[66]
UV-B辐射 抑制膜脂过氧化,降低细胞膜透性,影响抗氧化酶系统,植物体内营养物质吸收、分配[67,68]
CO2浓度增加 植物水分利用率提高,影响C、N平衡,根系分泌物增加[69,70]
