Abstract
In the present study to analyzed that the arbuscular mycorrhizal fungal spores in root colonization and spore population in rhizosphere soils samples in various medicinal at Paithal hills,Western Ghats of Kannur district, Kerala, India. Root and rhizosphere soil samples were collected during the month of August, 2018-March, 2019 from the surface to 30 cm depth as well as pH were also recorded. Totally 30 plant species belonging to 19 families were collected and identified. The present result showed arbuscular mycorrhizal spore population in the rhizosphere soil and root colonization of all the plant species. A total of 19 AM fungal spores were recovered from the rhizosphere soil samples in this study region. The Glomus was dominant had seen in rhizosphere soil samples in all the medicinal plant species. The maximum spore population was found in the rhizosphere soil samples of Mimosa pudica (590/100g of soil) which belongs to the family Mimosaceae and the lowest spore population was observed in the Terminalia bellirica 135/100g of soil) belongs to Combretaceae family. The highest 78 % AM fungal colonization was found in roots of Euphorbia hirta belongs to the family Euphorbiaceae. While the lowest 11 % AM fungal colonization was found in the root of Sida acuta belongs to the family Malvaceae.
Highlights
Arbuscular mycorrhizal fungi (AMF) are ubiquitous and abundant soil mycoflora and constitute an important functional component of the rhizosphere of 80-90% land plants in natural, agricultural and forest ecosystem (1)

Summary
Arbuscular mycorrhizal fungi (AMF) are ubiquitous and abundant soil mycoflora and constitute an important functional component of the rhizosphere of 80-90% land plants in natural, agricultural and forest ecosystem (1). In the tropics many crops are grown in acid infertile soils, where their establishment is frequently limited by the low levels of available phosphorus. In such soils an efficient mycorrhizal association can increase phopshorus uptake and crop yields (3). AM fungi play very vital role in uptake nutrients phosphorus from infertile and degraded soils. They infect large number of plants occurring in diverse environments. Microbial technologies hold great promise in the operation of scientific forest nursery managements by inoculating containers with biofertilizers viz, dinitrogen fixing organisms, phosphate solubilising organisms and mycorrhizae
