Mycorrhizas are the most common symbiosis between higher plants and microorganisms. In this research, the symbiosis effect of Glomus mosseae mycorrhize was evaluated on some corn varieties in pot culture as Factorial randomized complete design in three replicates in Gonbad Kavous University. The first factor was mycorrhizal fungi in two levels (soil inoculated (A1) and uninoculated (A2)) and second factor was different corn varieties in three levels (Single cross704 (B1), Pasha (B2) and Ferida (B3)). Results showed that inoculated of soil with mycorrhizal fungi had significantly negative effects on dry matter, plant height, leaf length, leaf width and diagonal of plant. Ferida variety had the greatest dry matter, fresh weight, leaf width and diagonal of plant among the corn varieties. A general result in this research was that Glomus mosseae mycorrhize fungi have significantly negative effects on growth of corn varieties in pot culture.
