The Investigation of Arbuscular Mycorrhizal Fungal Effect on Growth and Nutrients in Trifolium pratense in The Multi Metals Contaminated Soil

Two pot culture experiments were carried out to study the effects of arbuscular mycorrhizal inoculation on the growth and nutrients uptake of Trifolium pratense. In first pot experiment, efficiency of four mycorrhizal strains: Glomus mosseae; Glomus etanicatum; Glomus intraradices and mixed strains (combination of Glomus mosseae, Gigaspora hartiga and Glomus fasciculatum), on the uptake of nutrients was investigated. Results showed that Glomus mosseae had the highest efficiency of uptake, translocation and distribution of P, N and dry matter in alfalfa in comparison with the other strains. It can confirm existence of differences in ability of mycorrhizal strains in uptake and transport P into the shoot. A second experiment with heavy metal contaminated soil (Cd, Co, Pb and combinations) and inoculation to Glomus mosseae was executed. In this trial, uptake of nutrients depends on kind and mixture of metals was varied.
