摘要: 以草莓悬浮培养的细胞为对象, 研究了壳寡糖处理对活性氧代谢的效应。结果表明, 壳寡糖可诱导草莓悬浮培养细胞的活性氧迸发, 其峰值出现于20~30 min , 同时也可诱导活性氧清除酶活性上升,SOD 和CAT活性的最大值在处理后60~90 min。

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
