Solidago canadensis L., native to North America, is now an invasive plant worldwide. Its abundant seeds, rapid vegetative reproduction ability, and allelopathy to other plants are the main reasons for its successful invasion. It has negative impacts on the ecological environment of the invaded area and causes a reduction in local biodiversity and economic losses of agriculture and stock farming. Each part of the plant contains a variety of allelochemicals (terpenoids, phenolics, and flavonoids), including a large number of essential oil components. These allelochemicals can be released in various ways to inhibit the growth of adjacent plants and promote their invasion; they can also affect soil properties and soil microorganisms. This article summarizes the allelopathic effects of S. canadensis on other plant species and the interaction mechanism between it and the ecosystem.
加拿大一枝黄花原产于北美，现已成为一种全球性的入侵植物。其种子量大、营养繁殖能力强以及对其他植物的化感作用是其成功入侵的主要原因。它对入侵地区的生态环境产生负面影响，导致当地生物多样性减少以及农牧业经济损失。该植物的各个部位都含有多种化感物质（萜类、酚类和黄酮类），包括大量的精油成分。这些化感物质可以通过多种方式释放出来，抑制邻近植物的生长并促进其入侵；它们还会影响土壤性质和土壤微生物。本文综述了加拿大一枝黄花对其他植物物种的化感作用及其与生态系统之间的相互作用机制。
