| 摘 要： | 用来源于烟草赤星病菌（Ａｌｔｅｒｎａｒｉａ ａｌｔｅｒｎａｔａ）弱毒株ＴＢＡ１６的病菌激发子诱导烟草，产生了系统诱导抗性，最大诱导效应可达５４％。烟草幼苗经激发子处理后，苯丙氨酸裂解酶（ＰＡＬ）、过氧化物酶（ＰＯＤ）和多酚氧化酶（ＰＰＯ）活性有不同程度的增加，病程相关蛋白（ＰＲＰ）也有量的积累，在诱导后第１０ｄ产生的蛋白量最多。以水杨酸（ＳＡ）处理作阳性对照，结果表明，水杨酸诱导比激发子产生的诱导诱导效应高，各种酶活性均比激发子诱导产生的大，ＰＲＰ产生的量也较多。

| Abstract: | An elicitor derived from hypovirulent strain TBA16 walls of Alternaria alternata was studied on induced resistance and mechanism The elicitor induced tobacco resistance against brown sport with the highest effect of 54% After spraying of the elicitor,activities of phenylanine ammonia lyase (PAL),peroxidase (POD) and polyphenoloxidase(PPO) were increased in varying degrees PR-protein was also increased in content and showed the highest level at 10 days Salicylic acid was used as a positive mark,it showed not only higher induced effect,but also three enzymes activities and PR-protein in content than the elicitor did |
