Application of Arbuscular Mycorrhizal Fungi on Zinc and Iron Concentration in Wheat under Cadmium Stress

Abstract

For evaluate the application of a bio-fertilizer on zinc and iron concentration in wheat, under cadmium stress, a greenhouse experiment was conducted in factorial design with three replications. Treatments included Arbuscular Mycorrhiza levels (Control, Glomus mosseae and Glomus intraradices) and cadmium with six levels (0, 5, 10, 20,40 and 80  mg.kg-1). The measured data showed that the effects of treatments were significant on zinc and iron concentration. Arbuscular mycorrhizal fungi increasing zinc and iron concentration in plant. Glomus intraradices species increased zinc concentration in shoot and root % 252 and %222, respectively.  But Glomus mosseae species increased iron concentration in shoot and root % 148 and %170, respectively.
