Abstract: 

Mycorrhizae are symbiotic associations that form between the roots of most plants species and fungi. mycorrhizal symbiosis increase the resistence of plants against damaging agents of plants like drough and salinity stress. Also increase biomas and as result it is effective in sustainability and extention of the plantsin most of ecosystems. Tandoureh National park with 73435 hectares is located in dry locality of the north of khorassan the natural characteristics and climatic differences between the lowlands and the heights of this park results in variety and distribution of its plants. because about 30 persent plants of park are medicinal and forms a larg part of plant population of Tandoreh Park, the study of Mycorrhizal distribution of the plants for constant extention is necessary. In this research, complete soil and plant samples was collected in 8 stations in spring and summer from 26 platt (10 x10). soil samples were taken from the top 30Cm.after transforming the samples to laboratory, the fragile roots of the plants were separated and coded. Some root pieces were used for preparing longitudinal sections manually and were stained with lactophenol cotton blue followingestablished botanical staining procedures. soil samples were used to isolate Mycorrhizal spore and sprocarps. by sucerose centrifugation method. Results of this study showed that there were 54 vasular plantspecies, which 18 species were medicine plants The most persent of medicinal plants are in following familes Gramineae, Labiatae, Crucifereae, Compositeae. Species of Glomus contributed to the mycorrhizal symbiosis. Mycorrhizal association in the medicinal plant communities characterizes the importance of such symbiotic relationship in sustainable development and explotation of plant resources.
