FC, AMF0 and AMF1 refer to the filed capacity, AMF inoculation, without and with. Different letters in columns indicate significantly different values at p ≤ 0.05. *, **, and ns, indicate significance at 5% and 1% probability levels and non-significant, respectively. TSP, TAA, APX, GPX, SOD, AMF, S.O.V., C.V. and df refer to the total soluble protein, total antioxidants activity, ascorbate peroxidase, guaiacol peroxidase, superoxide dismutase, arbuscular mycorrhiza fungi, source of variation, coefficient of variation, and degree of freedom, respectively.
