Plant symbiosis with microorganisms and other living organisms cause plant species stability and plant community protection. Mycorrhizae is one of the most usefull symbiosis which both host plant and its fungi get benefit. Diversity of mycorrhizal fungi and the complicated relationship between plant and fungi community has been researched widely. In this research roots and rhizosphers of 10 families from eleven different habitats at Kerman were collected. 14 dominant plant species has been chosen and examined for their dominance and growth form as well as root colonization percentage. The highest percentage of colonization was observed in the root of Juniperus excelsa (84/27) while Euphorbia gedrosiaca showed the lowest colonization percentage (37/22). Mean of spore numbers per gr soil were varied between 0 to 15.06 where rhizosphere of Aceraceae and Chenopodiaceae had the highest and the lowest spore numbers respectively. There was a significant positive correlation between the percentage of infection with both spore numbers and soil pH in the study area. Three genus of mycorrhiza fungi including Glomus, Acaulospora and Entrophosporawere found in the soils.
