摘　　要：当前农业生产实践中植物诱抗剂的应用已日益广泛,部分原因在于对绿色农业理念的积极响应。植物诱抗剂在增强作物产量及其逆境抗性方面显示出潜在效益。然而,由于植物类型的差异、诱抗剂的种类、应用方法、施用时间以及作物所面临的环境胁迫类型等因素的多样性,目前尚难以明确确定植物诱抗剂对作物生长指标的具体有益影响。这种不确定性在一定程度上制约了植物诱抗剂在现代农业中的广泛推广及应用。本文通过对逆境胁迫下诱抗剂处理植物效应的Meta分析,系统评价诱抗剂对植物生物量、生长势和逆境抗性的影响,同时探究了不同条件对诱抗剂处理效果的影响程度。结果显示,诱抗剂能提高植物生物量,增强植物抗逆性,越早施用诱抗剂对鲜重的提升作用越明显,其中双子叶植物比单子叶植物在接受诱抗剂处理后产量提升更显著;而对不同胁迫,诱抗剂的效果有所差异。研究结果可为了解诱抗剂的作用效果及为实际生产实践中提高诱抗剂的应用效能提供理论支持。In the current agricultural production practice,the application of plant inducers has become increasingly widespread,partly due to the positive response to the concept of green agriculture.Plant inducers have shown potential benefits in enhancing crop yield and stress resistance.However,due to the diversity of factors such as differences in plant types,types of inducers,application methods,timing of application,and types of environmental stresses faced by crops,it is still difficult to clearly determine the specific beneficial effects of plant inducers on crop growth indicators at present.This uncertainty restricts the widespread promotion and application of plant inducers in modern agriculture to a certain extent.In this study,the effects of inducers on plant biomass,growth potential and stress resistance were systematically evaluated by Meta-analysis of the effects of inducers on plants under stress conditions.At the same time,the degree of influence of different conditions on the treatment effect of inducers were explored.The results showed that inducers could increase plant biomass and enhance plant stress resistance.The earlier the application of inducers,the more obvious the effect on fresh weight improvement.Among them,dicotyledonous plants showed a more significant increase in yield compared to monocotyledonous plants after treatment with inducers;The effect of inducers was different for different stresses.The research results can provide theoretical support for understanding the effect of inducers and improving the application efficiency of inducers in actual production practice.
