化感现象广泛存在于植物界,植物之间的化感作用对生态系统有着不可忽视的影响。综合近年的文献,试图对影响植物化感作用的重要因素进行总结,旨在为探究植物化感作用机制、合理利用化感作用提供一定的理论参考。当前研究表明:1)遗传因素(供体种间差异、供体种内品种间差异、受体植物)影响植物的化感作用;2)植物生长阶段、不同营养器官化感物质的种类含量有差异,化感作用受此因素影响;3)环境条件,如生境、光照、温度、水分、土壤结构、营养条件等在不同程度上影响植物化感物质的产生、释放及其效应;4)动物侵害导致植物化感物质合成、释放能力增强,以抵御外界干扰环境,微生物参与化感物质的降解过程,从而影响其最终去向。最后对植物化感作用的研究进行了展望。
化感現象廣汎存在于植物界,植物之間的化感作用對生態繫統有著不可忽視的影響。綜閤近年的文獻,試圖對影響植物化感作用的重要因素進行總結,旨在為探究植物化感作用機製、閤理利用化感作用提供一定的理論參攷。噹前研究錶明:1)遺傳因素(供體種間差異、供體種內品種間差異、受體植物)影響植物的化感作用;2)植物生長階段、不同營養器官化感物質的種類含量有差異,化感作用受此因素影響;3)環境條件,如生境、光照、溫度、水分、土壤結構、營養條件等在不同程度上影響植物化感物質的產生、釋放及其效應;4)動物侵害導緻植物化感物質閤成、釋放能力增彊,以牴禦外界榦擾環境,微生物參與化感物質的降解過程,從而影響其最終去嚮。最後對植物化感作用的研究進行瞭展望。

Allelopathy universally exists in the world, it would have a negligible impact among plants in the ecosystem. The current studies showed that plant allelopathy was genetic affected by the factors such as donor species difference, donor intraspecific differ-ences between species, receptors plant. Allelopathy was also affected by those like species of plant growth stage and the content of different vegetative organs of allelochemicals. Environmental conditions, such as habitat, illumination, temperature, moisture, soil structure and nutrient conditions affected the level, release and effect of plant allelochemicals in different extent. Animal invasion could cause the plant to synthesize and release the allelochemicals for enhancing ability to resist external interference. The microbial activities could control the pathway of the allelochemicals degradation. Also, the prospect of allelopathy research were discussed at last.
