摘要: 研究发现,用黄瓜亲和病原菌-细菌性角斑病菌诱导接种后可以使黄瓜叶片产生系统抗病性,且诱导抗病效果与诱导间隔期有关,其中以间隔24和48h效果较好。诱导接种后,接种叶片及其上位、下位叶片(未经诱导处理的叶片)中与抗性相关物质,如活性氧(H2O2)、超氧阴离子(NO2-)的含量、酯氧合酶(LOX)活性与对照相比均有明显的提高,且信号物质水杨酸(SA)的含量与未经诱导接种的叶片间有明显的变化,证实信号物质水杨酸在亲和病原菌诱导的抗病作用中起到抗病信息传递的作用。

关键词: 黄瓜, 亲和病原菌, 系统抗病性

Abstract: Systemic resistance of cucumber can be evoked when only one of the leaves inoculated by Pseudomonas syringae pv.1achryrnas, and the effect of protection is related with induced intervals, interval 24,48h has better effect. After induced inoculating , the content or activity of hydrogen peroxide (H2O2), Superoxide anion (NO2-), lipoxygenase (LOX) in inoculated leaf and it's upper,lower leaves (non-induced leaves) were much higher than control. Meanwhile, the content of salicylic acid increase obviously.

Key words: cucumber, aggressive pathogenic, systemic induced resistance
