Abstract

Abstract: To study the mechanismof inducing resistance on plant cells , the suspension strawberry cells were treated with different concentrations of oligochitosan. The results showed that oligochitosan could induce the changes of active oxygen metabolism in strawberry cells and the oxidative burst appeared in 20～30 minutes ; while the activities of the eliminated enzymes such as CAT and SOD increased gradually , the maximum changes of SOD and CAT activities happened in 60～90 minutes.

Key words: Oligochitosan, Strawberry, Active oxygen, Antioxidative enzymes
