Arbuscular mycorrhizal fungi (AMF) represent one of the major components of soil microbiota with a potential to not only aid in the establishment of the host plant, but also to enhance the overall plant growth. Despite increased understanding of the mycorrhizae, the mycorrhizal association, distribution and relative abundance for the majority of forest tree species are lacking. In the present study, we have isolated and identified the diverse species of arbuscular mycorrhizal fungi associated with the rhizosphere of Albizzia odoratissima (Black siris) located at an intensively managed site in the Forest College and Research Institute, Mulugu, Telangana, India. Rhizosphere soil samples collected from four different sites at the study location were processed for isolation of AMF, which were then identified using microscopic examination of morphological features. The AM fungi observed in the soil samples included 4 species of Glomus, and one species each of Acaulospora, Gigaspora, and Scutellospora. The most common and dominant mycorrhizal fungi associated with roots was found to be G. mosseae with an average spore density of 35/100g of soil. Microscopic observations of root samples confirmed the presence of arbuscules as well as vesicles. Overall findings suggest that the rhizosphere of A. odoratissima is highly rich in myco- biodiversity in the FCRI campus, but intensive management of appears to limit the distribution of mycorrhizae to the deeper layers of soil, resulting in less diversity.
