A native Glomus sp. from fields in Aydın province and effects of native and commercial mycorrhizal fungi inoculants on the growth of some vegetables

Seventy soil samples were collected from 25 different plant varieties grown in fields in Aydın province. Arbuscular mycorrhizal fungi (AMF) were found in 59 soil samples; 58 of these were identified as Glomus sp. and 1 as Gigaspora sp. Due to its adaptation characteristics, growth rates, and colonization properties, Glomus sp. was selected for further study. The effects of Glomus sp. and BioOrganics (Glomus aggregatum, G. clarum, G. deserticola, G. intraradices, G. monosporus, G. mosseae, Gigaspora margarita, and Paraglomus brasilianum) on tomato, pepper, and cucumber plant development were evaluated. The indigenous Glomus sp. showed positive effects on cucumber and tomato plant growth, but there was no significant difference in pepper plant growth when compared with the BioOrganics treatments. Glomus sp. colonization rates on roots of plants were 71% in cucumber, 72% in tomato, and 61% in pepper, and BioOrganics colonization rates were 47% in cucumber, 39% in tomato, and 36% in peppers.
