Abstract

In order to evaluate the effect of mycorrhiza-like fungus ,Piriformospora indica, and mycorrhiza fungus ,Glomus mosseae, on corn (Zea mays L. cv. SC 704) electrolyte leakage and relative water content (RWC) under different limited irrigation regimes and phosphorus, a field experiment was conducted in split factorial design at two stations of Gharakhil and Bayekola during 2015. Treatments were different irrigation methods at three levels (100, 75 and 50% of crop water requirement) in main plots, four levels of inoculation (control, Pi inoculation, Gm inoculation and Pi + Gm inoculation) and three levels of phosphorus (control, 50 and 100 % of crop requirement) in sub plots. According to the results, RWC was decreased significantly by limited irrigation regimes in both stations, while the amount of electrolyte leakage significantly increased. Simultaneous inoculation of Pi and Gm non-significantly increased RWC and decreased electrolyte leakage as compared to the control. Overall, results represented a non-positive effect of two applied fungi for ameliorating the water deficit stress on RWC and electrolyte leakage.
