Abstract: | Plant species dominance and arbuscular mycorrhizas (AMs) were evaluated in four different habitats of Cholistan desert, Pakistan.
The sites were selected on the basis of variations in topography, floristic composition and biotic interference. The phytosociological
data revealed obvious differences in the floristic composition, plant species diversity, AM colonization and arbuscular mycorrhizal
fungi (AMF) spore densities in the rhizospheres. The vegetation pattern and composition was governed by topography and edaphic
characteristics of a particular site. Grasses were dominant and main components of vegetation at all the study sites and were
invariably mycorrhizal. Some plant species were mycorrhizal at one site but non-mycorrhizal at the other. The AMF survey reported
here offers an important starting point from which to analyse AMF community structure in different phytosociological habitats
and land uses of Cholistan desert. |
