STUDIES ON THE ARBUSCULAR MYCORRHIZAL FUNGAL BIODIVERSITY IN THE PLANT SPECIES OF YELLANAHALLI HILLS, VALLEY VIEW OF NILGIRIS, UDHAGAMANDALAM, TAMIL NADU, INDIA
- AMF Spore population, medicinal plants, Yellanahalli hills.
The present study to investigated that the arbuscular mycorrhizal fungal root colonization and spore population in some medicinal at Yellanahalli hills, valley view of Nilgiris, Udhagamandalam, Tamilnadu, India.Root and rhizosphere soil samples were collected during the month of August, 2017 - March, 2018 Soil pH
was to be recorded. From the study results revealed that totally 25 plant species belonging to 13 families were recorded root colonization and rhizosphere spore population. A totally 12 Arbuscular mycorrhizal fungal species belonging to 7 genera and 2 different Orders were isolated and identified. The maximum spore
population was found in the rhizosphere soil samples of Justicia procumbens (380 /100 g of soil) which belongs to the family Acanthaceae and the lowest spore population was observed in the Crotalarieae juncea(102 / 100 g of soil) belongs to Fabaceae. Among these plant species the highest 81% AM fungal infection was
found in roots of Solanum nigrum belongs to the family Solanaceae While the lowest 23 % AM fungal association was found in the root of Verbascum thapsus belongs to Scrophulariaceae.
