This study examined the associations between an invasive alien plant (Solidago canadensis L.) and arbuscular mycorrhizal fungi (AMF) in relation to the invasion history of S. canadensis on Chongming Island, China. A significant positive correlation was found between invasion time and AMF colonisation rate. The total number of AMF species increased with increasing invasion time and was positively related to the number of plant species occurring in plant communities, suggesting that the invasion time and plant diversity influence the diversity of AMF species. The relative abundance of two dominant AMF species, Glomus mosseae and G. constrictum, varied systematically with invasion time. In dry habitats, the relative abundance of G. mosseae increased with the invasion time of S. canadensis, while that of G. constrictum decreased with the invasion time. However, these relationships did not exist in the wet habitats.
本研究针对中国崇明岛上加拿大一枝黄花（Solidago canadensis L.）的入侵历史，探讨了外来入侵植物与丛枝菌根真菌（AMF）之间的关联。研究发现入侵时间与AMF定殖率之间存在显著正相关。随着入侵时间的增加，AMF物种总数增加，且与植物群落中出现的植物物种数量呈正相关，这表明入侵时间和植物多样性会影响AMF物种的多样性。两种优势AMF物种，即摩西球囊霉（Glomus mosseae）和缩球囊霉（G. constrictum）的相对丰度随入侵时间而系统变化。在干旱生境中，摩西球囊霉的相对丰度随加拿大一枝黄花的入侵时间增加，而缩球囊霉的相对丰度则随入侵时间下降。然而，在潮湿生境中不存在这些关系。
