Antioxidant enzyme activity—(A) Superoxide dismutase (SOD) in shoot; (B) SOD in root; (C) Catalase (CAT) in shoot; (D) CAT in root; (E) Ascorbate peroxidase (APX) in shoot; and (F) APX in root—of non-salinized and salinized summer squash plants, as affected by seed priming with 1.5 mM GA, 0.005 mM JA, and mixture of them. Data represent mean of three replicates (n = 3) with error bars indicating standard error of the mean. Bars carrying different lowercase letters are significantly different at p < 0.05 according to Duncan’s multiple range Test. p values for two-way ANOVA are reported in Table 1.
