| 摘 要： | 从黄瓜发生霜霉病的叶片中提取到两种细胞壁降解酶：羧甲基纤维素酶(Cx)和p一葡萄糖苷酶，二者活性显著高于对照，证明在霜霉病菌侵染寄主过程中这两种细胞壁降解酶起到了关键作用。

| Abstract: | The zymin was extracted from cucumber leaf infected by Pseudoperonospora cubensis．Among zymin，earboxymethyl eellulase and —glueosidase showed higher activity than contro1．This conclusion testified two kinds of eellulase acted as key action while the pathogen Was invading host．This research ofered foundation in the ory for studing the pa thogenesis mechanism of P．cubens． |
