Examined the soil properties which caused distinct populations of VA mycorrhizal fungi to occur at adjacent sites in a semi-arid, Mediterranean environment in Western Australia. When inoculated into the soil in which they did not occur naturally 1) the fungi infected fewer roots and produced fewer spores than in their soil of origin; and 2) fewer spores of the dominant fungi (Site I: Acaulospora laevis, Site II: Glomus spp (WUM 2 and WUM 3) germinated, and they produced shorter germ tubes than in their soil of origin. Soil pH is likely to be important in limiting distribution of A. laevis and Glomus sp. (WUM 3). -from Authors
