摘　　要：在黄瓜褐斑病菌毒素的作用下,黄瓜品种的根数、根长、芽长受到了抑制,根的电导值及叶片的苯丙氨酸解氨酶(PAL)活性升高。抗病品种的根数、根长、芽长受毒素的影响较感病品种小,即感病品种对毒素敏感,且抗、感品种的电导值差异达显著水平。抗病品种的PAL活性增加幅度较感病品种大。When plants were treated with Corynespora cassiicola toxin,the root number, root length,shoot length decreased,but the electrical conduction rate（ECR） of root and activity of phenylalanine ammonia lyase（PAL） in cell increased.The susceptible cultivars were more sensitive to toxin than resistant varieties.There was a significant difference in electrical conduction rate between the resistant and susceptible varieties.The increase in PAL activity in resistant varieties were larger than that in susceptible varieties.
