| Abstract: | The activities of superoxide dismutase (SOD), peroxidase (POX), catalase (CAT), and the content of glutathion as the system of eradicating active oxygen gradually decreased during salt stress in four mulberry varieties (Husang 32, Xinyizhillai, Yu151, Tongxiling), but were still remained higher levels. These changes were coincided with lower increases in membrane relative permeability and lipid peroxidation. The strong capacities of eradicating active oxygen maintained in mulberry under salt stress were likely correlated with the salt tolerance of mulberry. |
