摘要:

入侵植物是危害最广泛、最持久的入侵生物类群之一,严重破坏生态系统结构与功能。当前,入侵植物化感作用研究仍存在物种覆盖范围有限、室内模拟实验占比高、群落尺度互作研究不足等问题,难以全面阐释入侵植物的化学竞争机制。系统梳理入侵植物化感物质的组成、释放机制及化感抑制等方面的研究进展,明确了入侵植物主要通过雨雾淋溶、根系分泌等途径释放酚酸类、萜类、黄酮类等化感物质,从而抑制本土植物生长。同时,部分入侵植物的化感物质具有自毒效应,可在一定程度上约束入侵物种种群无限制扩张。此外,氮沉降可调控入侵植物与本土植物的化感竞争能力。未来研究应聚焦于植物群落尺度,结合多维度生态视角,深入解析全球尺度下入侵植物化感效应对植物群落构建与演替的调控机制,以深化对植物入侵机理的认识,为构建生物入侵预警体系、研发入侵植物绿色防控技术提供理论依据。

Abstract:

Invasive plants are among the most widespread and persistent invasive taxa,severely disrupting ecosystem structure and function.Current research allelopathic effects of invasive plants is constrained by limited species coverage,a high proportion of laboratory simulation experiments,and insufficient studies on community-scale interactions,which impede the systematic elucidation of chemically mediated competition mechanisms.By synthesizing reviewing advances in the composition,release mechanisms,and allelopathic inhibition of allelochemicals,this review reveals that invasive plants primarily release phenolic acids,terpenoids,and flavonoids through rainfall leaching and root exudation to suppress native plant growth.Notably,some invasive plant allelochemicals also exhibit autotoxic effects,which may partially restrict excessive population expansion of invasive species.Future research should focus on plant community scales and integrate multidimensional ecological perspectives to clarify how allelopathy modulates plant community assembly and succession under global change.These findings provide theoretical support for understanding plant invasion mechanisms,supporting the development of early-warning frameworks and sustainable management strategies for invasive plant species.

Key words: invasive plants, allelopathy, allelochemical composition, release mechanisms
