摘　　要：植物根系分泌物是指植物根系释放到根际环境中的各种化合物,是根系与周围环境进行物质交换的重要媒介,对植物生长、营养吸收、抵御病害等具有重要作用。在胁迫条件下,根系分泌物参与提高植物资源利用效率作用过程,并可促进植物与土壤微生物间的相互作用。本文综述了根系分泌物的组成和转运方式,及其在促进植物营养吸收中的应用;重点综述植物为应对生物和非生物胁迫,调控根系分泌物释放变化动态的研究进展;并讨论种植方式改变所产生的根系分泌物在病虫害防治中的应用。该综述可为深入了解植物根系的生态功能和适应机制提供理论指导。Plant root exudates refer to a variety of compounds released into the rhizosphere by plant roots,serving as a crucial medium for material exchange between the roots and their surrounding environment.Plant root exudates play an important role in plant growth,nutrient absorption,and disease resistance and so on.Under stress conditions,root exudates are involved in enhancing plant resource use efficiency and promoting interactions between plants and soil microorganisms.This paper reviews the composition and transport mechanisms of root exudates,as well as their application in promoting plant nutrient uptake.It focuses on the research progress in regulating the dynamic release of root exudates by plants under biotic and abiotic stresses.The paper also discusses the application of different root secretions,which produced by planting practices,to control pests and diseases.This review will provide theoretical guidance for a deeper understanding of the ecological functions and adaptive mechanisms of the plant root system.
