摘　　要：化感物质是植物重要的次级代谢产物,植物化感作用是通过化感物质来实现的。通常化感物质对其他生物具有抑制活性,且作用机制独特。因此植物化感物质是研发生物农药和创制农药新型作用靶标的重要模板。介绍了植物化感物质的研究情况及种类,重点阐述了化感物质的作用机理,提出今后进一步研究的方向主要为:优化化感物质的提取及分离方法,高效精准获得新型化感物质;运用多组学及多种分子生物学技术深入剖析化感物质的作用靶标;加强田间应用试验,挖掘在生产实践中能有效利用的化感物质,推进研究成果的快速转化,形成有效产品。Plant allelopathy is realized through allelochemicals which are important secondary metabolites of plants.Many allelochemicals show inhibitory activity against other organisms generally,and have an unique inhibitory mechanism,therefore they are an important template for the development of biological pesticides and provide new targets for the creation of pesticides.This paper reviews the situation of plant allelochemicals research,briefly introduces the classification of allelochemicals,as well as focuses on the action mechanism of allelochemicals.And finally,it proposes the future research directions:optimizing the extraction and separation methods of allelochemicals to obtain new allelochemicals efficiently and accurately;using multi-omics and molecular biology techniques to analyze the action targets of allelochemicals;strengthening field application test to excavate allelochemicals that can be effectively used in production,and promoting the rapid transformation of research results to form effective products.
