This study was conducted to investigate the morphological identification of vesicular-arbuscular mycorrhiza (VAM) on bulbous plants in the Taurus Mountains in Turkey. Thirteen soil samples and bulbous roots were taken from the rhizosphere of bulbous plants. The soils were analyzed for the number of VAM spores and chemical and physical properties. In addition, the roots were examined for infection levels, and morphological identification of VAM spores was made. All tested plants are considered mycorrhizal plants. We determined three spore species (Glomus mosseae, Glomus hoi and Scutellospora calospora) from the surveyed soils. The spore distribution rates were as follows: G. Mossea 61.54 %, G. Hoi 23.07 % and Scutellospora calospora 15.38 %. Results suggest that VAM fungal spores and root colonization display variation in rhizosphere under bulbous plants in different ecological conditions.

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.

Plant growth and physiological response of sesame (Sesamum indicum L.) were studied in controlled environment using normal soil and indigenous Vesicular-arbuscular mycorrhiza (VAM) fungi treated soil. The seedlings of Zea mays were inoculated with Giguspora species of VAM (Glomus fasiculatum) and the inoculum was multiplied with help of Zeamays seed bed. Sesame seeds were then inoculated into the bed and it was found that the plant height, shoots lengths, roots, biomass of shoot and roots were considerably increased in the mycorrhizal plants. The effect of VAM infection was assessed in pot experiment. In this comparative study, specific mycorrhizal fungi had consistent effects on various growth parameters such as the number of leaves, number of roots, shoot length, biomass of shoot and roots and biochemical parameters were observed at various time intervals by statistical analysis using two way ANOVA, it was confined with mycorrhizal and non-mycorrhizal infected plants. It was found that the ability of isolates to maintain the plant growth effectively in the case of mycorrhizal seedlings shows a maximum absorbtion of 0.77 ±0.2, shoot length is about 8.34 ±0.2, count of root and leaves are about 8.10 ±0.3, 5.6 ±0.3 respectively under mycorrhizal infection in 30days of analysis and had a positive effect on the growth at all intervals. Biochemical analysis were carried out to estimate the total chlorophyll, chrophyll A, chlorophyll B and Carotenoids contents and it was analyzed to be 9 ±0.5 mg/g, 8.3 ±0.5 mg/g, 3.6 ±0.5 mg/g, 4 ±0.3 mg/g respectively. At the 30th day of analysis for the mycorrhizal plants, it was found to be high in mycorrhizal seedlings which shows the symbiosis had improved the nutrient uptake of cultivated plants. Nevertheless G. fasiculatum was found to be the most efficient fungus and exhibited the highest levels of mycorrhizal colonization, as well as the greatest stimulation of physiological parameters.
