The present study to investigate the arbuscular mycorrhizal fungal root colonization and spore population of some medicinal plants species at Theerthamalai hills Western Ghats of Dharmapuri district, Tamil Nadu. Root and rhizosphere soil samples were collected during the month of August, 2010-March, 2011. From the surface to 20 cm depth as well as pH were also measured. Totally 42 plant species belonging to 24 families recovered Arbuscular mycorrhizal fungal spore and root colonization. The results of the present study arbuscular mycorrhizal fungal spore population in the rhizosphere soil and root colonization of all the plant species. The maximum spore population was found in the rhizosphere soil samples of the plant species Leucas aspera (386/100g of soil) which belongs to the family Lamiaceae and lowest spore population was observed in the  Wrightia tinctoria (117/100g of soil) belongs to Apocyanaceae.

The present study was carried out the arbuscular mycorrhizal fungal root colonization and spore population diversity some medicinal plants species at Bargur hills Western Ghats of (Anthyur taluk), Erode district, Tamil Nadu, India. Root and rhizosphere soil samples were collected during the month of August,2017-March, 2018 from the surface to 20 cm depth as well as pH were also measured. Totally 25 plant species belonging to 19 families recovered Arbuscular mycorrhizal fungal spore and root colonization. The results of the present study arbuscular mycorrhizal spore population in the rhizosphere soil and rootcolonization of all the plant species. A total of 22 AM fungal species belonging to 7 genera and 2 different orders were recorded from the rhizosphere soil samples of 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 Leucas aspera (470 /100 g soil) which belongs to the family Lamiaceae and lowest spore population was observed in the Tephorosia purpurea (123 /100g soil) belongs to Fabaceae.

The present investigation has brought out the AM fungal association in some plant species of Kodikuthimala, Malappuram district Kerala. Totally, 25 plant species belongs to 15 families were analyzed for arbuscular mycorrhizal association. The root samples of all collected plant species showed mycorrhizal infection. The percentage of colonization was varied with plant species and it ranges from 12 (Commelina benghalensis) to 79% (Sida rhombifolia). Maximum spore population was observed in Gloriosa superba (574/100g of soil) and minimum in Euphorbia hirta (143/10g of soil). Totally 26 AM fungal species belongs to 13 genera were found. Among this Glomus was most dominated. In most of the plants, spores of Rhizophagus fasciculatus are seen. Present study confirms the Arbuscular Mycorrhizal association in the collected plant species.

The occurrence of arbuscular mycorrhizal fungi (AMF) in cultivated soils of Poland was characterized based on 15-year investigations. Spores of AMF were isolated from both field-collected root-rhizosphere soil mixtures and trap cultures established with a part of these mixtures. The mixtures were collected from under 41 plant species. The plant species most frequently sampled were <i>Hordeum vulgare, Triticum aestivum</i>, and <i>Zea mays</i>. Spores of AMF were found in 97,5% of the field-collected root-soil samples and in 95,5% of trap cultures. The AMF predominating in populations of the spores revealed were members of the genus <i>Glomus</i>. The spores recovered belonged to 36 species. The AM fungal species most frequently occurring in cultivated soils of Poland were <i>Glomus caledonium, G.constrictum, G.deserticola</i>, and <i>G.mosseae</i>.
