ACTIVITY OF REDOX ENZYMES IN SYMBIOTIC SYSTEMS OF SOYBEANBRADYRHIZOBIUM JAPONICUM UNDER THE ACTION OF EXOGENOUS LECTIN AND DIFFERENT WATER SUPPLY

Abstract

The activity of ascorbate-, guaiacol peroxidase and catalase in soybean plants, inoculated with nodule bacteria under the influence of exogenous lectin and different water supply, was studied. It was shown changes in activity of main antioxidant enzymes in the formation and functioning of symbiosis, at the same time character and extent of these changes depended on the method of using the lectin, level of water supply and plant development phase. The established during research regularity can confirm participation of this protein in the regulation of the formation and functioning of the symbiosis and the reaction inoculated soybean plants to drought.
