枣疯病植原体对枣树叶绿素及几种保护性酶的影响
Effect of Jujube Witches' Broom(JWB) Phytoplasma on the Chlorophyll and Several Protective Enzymes in Jujube Trees
摘要
Abstract
The leaves of behaved healthy,leaves changed by flower and tiny leaves with jujube witches' broom (JWB ) of Ziziphus jujuba cv. Zanhuangdazao and the leaves of healthy tree as the control were used in this paper. The content of chlorophyll,soluble protein,MDA and three kinds of protective enzymes activity of different leaves at different growth stages were determined to reveal the effect of phyloplasma on jujube physiological metabolism. The results showed that the content of chlorophyll and soluble protein of diseased leaves were significantly lower than that of healthy leaves. The POD, SOD activity and MDA content of diseased leaves were significantly higher than that of healthy leaves,PPO activity was not significantly changed,leaves changed by flower was the most significantly changed than the other diseased leaves. These results indicated that the photosynthesis and protective enzyme system of diseased trees were significantly affected by jujube witches' broom phytoplasma.关键词
