Cholistan desert where the soils are with low nutritional level, vesicular - arbuscular mycorrhizal fungi (VAMF) being an integral part of the under ground system play a pivotal role in the establishment of natural plant communities especially in the disturbed habitats. In the present studies we investigate the effect of particular soil properties on the sporulation and infection of VAMF in two adjacent soils. Predominant mycorrhizal fungi Glomus fasciculatum and Glomus albidum was found to be well adopted in their original habitats (i.e. Site-I and Site-II) and could not show commendable results in the-alien soils as inoculum. Glomus fasciculatum produced higher number of spores to that of Glomus albidum in their native soils (670 and 388 spores respectively). However, later species cause maximum infection (84%) as compared to formal (28%) VAMF species. It was concluded that heterogeniety in edaphic properties are responsible for the distribution, predomination, sporulation and infection potential of VAMF.
