Abstract
The ecological mechanisms of AM fungal diversity ensure successful management for conservation and restoration of natural ecosystems. Here the study contacted to estimate the diversity of AM fungal and their function in Velliangiri hills, Western Ghats, Coimbatore. The community structure of AM fungi, as
determined by number of spores present in 100g of soil, varied with sampling time in plant community. And all so the morphological identification was done by microscopic characters. Soil properties like pH, macro and micro nutrient and the climate data were collected for all tree years to know their impact on fungal
community. The overall result conform the root colonization and spore population were higher in winter season and also lower in rainy. Totally 30 AM fungal species from 10 genera were identified the important genera were Acaulospora, Ambispora, Claroideoglomus, Funneliformis, Gigaspora, Glomus, Racocetra,
Redeckera, Rhizophagus and Scutellospora. Among these five genera, Glomus occurred most frequently. In general, Rhizophagus fasciculatus was found to be most abundant species. Consequently, this result conform the rich diversity in the study area. This symbiotic relationship had important roles in establishment of plant community of this area.
