In order to reveal effect mechanism of crop reactive oxygen species metabolic system under exogenous chitosan to ozone stress, open top chambers were utilized to investigate the change of reactive oxygen species production rate, lipid peroxidation extent, anti-oxidative enzymes activities and antioxidant content in soybean (Glycine max) leaves. Exogenous chitosan treatment relieves the aggravation of reactive oxygen species damage through ozone stress, which represents protective efficacy to soybean, the superoxide anion production rate, hydrogen peroxide content, malondialdehyde content and membrane permeability decreased, while anti-oxidative enzymes activity and anti-oxidative substances increased. But the alleviation of exogenous chitosan to ozone is limited.
为揭示外源壳聚糖对臭氧胁迫下作物活性氧代谢系统的影响机制，采用开顶箱研究了臭氧胁迫下大豆叶片活性氧产生速率、脂质过氧化程度、抗氧化酶活性和抗氧化物质含量的变化。外源壳聚糖处理缓解了臭氧胁迫对活性氧损伤的加重，对大豆具有保护作用，超氧阴离子产生速率、过氧化氢含量、丙二醛含量和膜透性降低，而抗氧化酶活性和抗氧化物质增加。但外源壳聚糖对臭氧的缓解作用是有限的。
