Diversity of AM Fungi in Rhizosphere of Three Acacia Species in Thar desert Rajasthan

Pollution has become a worldwide environmental issue it has created many health problems.A study was conducted to access the diversity of AM Fungi and relationship of three Acacia Species in Thar Desert Rajasthan. For this purpose, soil samples along with the plant root were collected from different areas of Thar Desert. The survey of AM fungi associated with Acacia nilotica , Acacia Senegal and Acacia catechu in Thar Desert revealed that eleven AM fungi commonly occur in the rhizosphere viz.,Glomus aggregatum, Glomus constrictum, Glomus deserticola, Glomus fasciculatum, Glomus macrocarpum Acaulospora laevis, Scutellospora calospora and Scutellospora nigra. Acaulospora morrawae, Gigaspora gigangea, Gigaspora margarita. Mycorrhizal spore population at various localities varied from 310-450 spores per gram of soil and percentage root colonization by different AM fungi at various localities varied from 52-78 percent. Abiotic Factor of rhizosphere soil of Acacia species is different at various localities. The soil pH at various localities varied from 6.8-8.1, while soil moisture varied from 6.5-8.2 percent organic carbon ranged from 0.8-1.4, soil phosphors was 38-60 k/ha and soil nitrogen 19-28 k/ha at different localities
