丛枝菌根真菌（AMF）对植物生态系统的影响已被广泛报道。在这项研究中，我们探讨了本地和引进的 AMF 在促进优势植物和从属植物物种生长方面的差异。在温室实验中，来自亚热带草原的优势种和附属种被本地AMF 或引入的AMF（球囊霉）定殖。生物量显示，优势菌对原生AMF的菌根依赖性(MD)远高于从属菌根，而引入AMF取代原生AMF后，菌根对引入AMF的MD发生变化。观察到生物量促进和磷吸收增加之间存在密切关系，表明 AMF 增强根系养分吸收的重要作用。我们的结果表明，植物群落结构部分由天然 AMF 的 MD 决定，并且可以通过引入外源 AMF 物种进行修改。
The impact of arbuscular mycorrhizal fungi (AMF) on plant ecosystems has been intensively reported. In this research, we explored the difference between native and introduced AMF in promoting the growth of dominant and subordinate plant species. In glasshouse experiments, dominants and subordinates from subtropical grasslands were colonized by native AMF or introduced AMF,Glomus versiforme. The biomass revealed that mycorrhizal dependencies (MD) on the native AMF of the dominants were much higher than those of the subordinates, while MD on the introduced AMF changed following the replacement of native AMF with introduced AMF. A close relationship between biomass promotion and increase in phosphorus uptake was observed, indicating the important role of AMF-enhanced nutrient acquisition by roots. Our results show that plant community structures are partly determined by MD on native AMF, and could be modified by introducing exogenous AMF species.
