Mycorrhiza is a mutualistic relationship between plant roots and fungal hyphae. Mycorrhizal associations significantly contribute to the ecological sustenance of the stressful environments such as arid and saline habitats of Mouteh region, Iran. Mouteh Wildlife Refuge, a 220000 ha reserve, is located in the northwest of Isfahan province and south of the Markazi province. Climate of the region is arid to semi- arid with hot Summers. Nowadays, management of plant-microbe symbioses such as Vesicular-Arbuscular Mycorrhiza (VAM) is considered for restoration of disturbed ecosystems and sustenance of natural ecosystems. In this investigation, we have studied occurrence of VAM in the rhizosphere of major medicinal plant species in Mouteh. Eight sampling stations were selected. Plant and soil samples were collected from 32 plots (10 xl0 m) during Fall and Spring of 2003. Soil and root samples from the top 30 cm were collected and relevant ecological data were recorded. Samples were transferred to the laboratory in proper conditions and were stored properly. Soil was sieved through 720, 420. 250.170. 106 & 38 mesh screens to remove large pieces. Root pieces were isolated and air-dried. The soil was analyzed chemically, physically and biologically in the lab. Some root pieces were used for preparing longitudinal sections manually and were stained with lacto phenol cotton blue. Soil samples were used to isolate mycorrhizal spores and sporocarps by sucrose density centrifugation method. Plant and mycorrhizal species were identified taking advantage of their macroscopic and microscopic characteristics and using reliable flora and fungal keys, respectively. Results of this study showed that there were 315 vascular plant species belonging to 209 genera and 55 families from which 50 species were medicinal plants. Legominosae, Compositae, Cruciferae and Poaceae have the most number of medicinal species. Dominant VA mycorrhizal species was Glomus geosporum. Presence of mycorrhizal associations in the medicinal plant communities characterizes the importance of such symbiotic relationship in the sustainable exploitation of plant resources.
