| 摘 要： | 补骨脂粗提物处理两叶一心生长期的黄瓜幼苗,研究其诱导黄瓜抗病性的生理生化机制。补骨脂提取物在40和400mg/L浓度下,黄瓜体内过氧化物酶、多酚氧化酶、苯丙氨酸解氨酶等一些防御酶活性均在处理后7～9d达最高;几丁质酶活性在处理后2、3d时达到高峰,分别是对照的1.64、1.5倍,然后逐渐下降,分别在7、9d基本回到对照水平;β-1,3-葡聚糖酶活性在处理后2、5d达到最大值,酶活性是对照的2.02、1.34倍,然后迅速下降,处理后分别在5、9d基本回到对照水平。从所测定的几种酶活性变化时间来看,补骨脂提取物处理黄瓜幼苗后,首先使黄瓜体内的几丁质酶和β-1,3-葡聚糖酶等病程相关蛋白活性升高,然后在两者的作用下,诱导了黄瓜体内过氧化物酶(POD)、多酚氧化酶(PPO)、苯丙氨酸解氨酶(PAL)等一些防御酶活性的提高。

| Abstract: | Cucumber seedlings were treated with Psoralea corylifolia L.extract at two-leave-one-heart stage,the defensive enzymes of cucumber were studied and the results showed that activities of peroxidase (POD),polyphenol oxidase(PPO),phenylalanine ammonialyase(PAL) of cucumber leaves were increased to highest level after 7 to 9 d at 40 mg/L and 400 mg/L.Activities of chitinase achieved at peak level after 2 to 3 d and were 1.64 and 1.5 fold of check,then decreased gradually and resumed to normal level after 7 to 9... |
