Arbuscular Mycorrhizal Fungi in Alleviation of Drought Stress on Grain Yield and Yield Components of Mungbean (Vigna Radiata L.) Plants

To investigate the effect of mycorrhizal fungi on reduction of drought stress on related grain yield and yield components of mungbean plants, a pot culture was conducted based on Randomized Completely Design with three replications in Urmia University in 2009. The experiment with four irrigation regimes (25, 50, 75 and 100 mm of evaporation from a class A pan) were assigned at the first factor and two mycorrhiza species; Glomus mosseae, Glomus intraradices and a non-inoculated treatment at the second factor. Results showed that in both mycorrhizae species significantly (P
