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
