摘　　要：由多个不同的抗病诱导因子组成植物抗病诱导系统的1个子系统。每个因子都是这个系统中的1个要素。系统的性质不但取决于系统中的要素,还取决于要素的结构。合理的配伍可以使要素与要素之间、要素与系统之间的关系得以优化,使系统的功能得以强化。把筛选得到的多个不同的抗病诱导因子进行配伍,组合成新的"诱导组合体",其诱导效应比单一因子显著提高;用不同的"诱导组合体"进行"相继诱导"和"循环诱导",则进一步提高诱导效应,对黄瓜白粉病的田间防治效果达到78.16%,高于常规杀菌剂的防治效果。Subsystem in plant disease resistance induction system was composed of different disease resistance induction factors which were the important elements in the system. Properties of the system depended not only on elements, but also on the structure. Rational structure optimized the relationship between elements of the system, which made the system function strengthened. New induction combination consisting of several different selected disease resistance inductive factors made inductive effect improved significantly. Successive induction and repeated induction based on different inductive combination made the effect further improved, and its effect on controlling cucumber powdery mildew reached to 78.16% and was higher than normal fungicide.
