FIGURE 4.
Effect of bacterial inoculation on antioxidant enzyme activities: (A) superoxide dismutase (SOD), (B) glutathione reductase (GR), (C) ascorbate peroxidase (APX), and (D) catalase (CAT) in leaves of S. fruticosa plants, in the absence (0 mM NaCl) and in the presence of NaCl (600 mM NaCl). Values are the means standard deviation of five replicates. Values sharing the different letters indicate significant differences between treatments at the 5% level (Duncan’s).
