The effect of different soluble P-fertilizer forms (Ortho-A, Poly-B and Ortho-B) and doses (0, 30 and 45 ppm of P) on superoxide dismutase (SOD) (A), ascorbate peroxidase (APX) (B) and Catalase (CAT) (C) of wheat plants grown under salinity, measured 12 Weeks After Sowing (WAS). C+ salt-stressed and unfertilized plants, C−: unfertilized plants without salt stress. Statistical analysis was performed using one-way ANOVA and SPSS data processing software. Duncan’s test was used for the comparison of means. Treatments having a different letter(s) are significantly different at the 5% level.
