Abstract: Background and Objective: Arbuscular mycorrhizal fungi (AMF) and rhizobia stimulated biological N-fixing in leguminous plants.This work was aimed to analyze the effects of single and dual inoculation with AMF and rhizobia on growth and mineral nutritional acquisition (especially N) in white clover (Trifolium repens L.). Materials and Methods: An arbuscular mycorrhizal fungus Rhizoglomus intraradices and a rhizobia Rhizobium trifolii were inoculated into rhizosphere of potted white clover and plant growth, soluble sugar, soluble protein, leghemoglobin, mineral nutrition and soil glomalin concentrations were analyzed after 100 days of inoculations.Results: Rhizobium trifolii inoculation positively promoted root mycorrhizal colonization.Single AMF or rhizobia treatment significantly increased the number of stolon joints and root biomass, which was related with symbiont-stimulated increases of soluble sugar and soluble protein.A higher root leghemoglobin concentration was found in -AMF+Rh plants than in non-inoculated plants.The AMF or rhizobia inoculation mainly promoted leaf nutrition acquisition including N. Conclusion: So, it was concluded that AMF and rhizobia jointly stimulated plant growth, root soluble sugar and soluble protein accumulation in white clover, while AMF did not show a cooperative effect on N fixation of rhizobia.
