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. |
