摘要：

Responses to a range of environmental conditions were examined and compared in three populations of Glomus mosseae from dissimilar habitats to assess phenotypic plasticity. The G. mosseae populations were observed (1) in three soils with different physical-chemical characteristics, (2) at three different levels of soil moisture and (3) under three temperature regimes. Using Melilotus officinalis as host, measurements were made of mycorrhiza formed, spore production and influence of the endophytes on host biomass production and shoot phosphorus concentration. The three G. mosseae populations were found to vary significantly in their responses under different environmental conditions and in their breadth of tolerance to environmental factors. Results were interpreted as indicating that phenotypic plasticity is variable among populations of G. mosseae but not sufficient to explain the wide distribution of this fungus.
