Effects of reactive oxygen species metabolic system on soybean (Glycine max) under exogenous chitosan to ozone stress.
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.
