Table 4.

Mean values of superoxide dismutase (SOD), catalase activity (CAT), and malondialdehyde (MDA) traits for three Hail landraces under four NaCl stress treatments. Values are the mean of four replications. According to Tukey’s test, different letters within the same columns show significant differences (p < 0.05). The higher cases are the differences among genotypes, and the lower cases are the differences among treatments’ mean. ns: means not significant.
