The effect of Sphingomonas SaMR12 on plant (a) SOD activity, (b) POD activity. (c) CAT activity and (d) APX activity in both shoots and roots. The solid line, non-inoculated plants; the dashed line, SaMR12-inoculated plants. Plant samples were harvested after 7 d of treatment. The vertical line on each bar shows the standard deviation (n = 3). The different letters on the error bars indicate significant differences among treatments at p < 0.05 in the shoot and the root, respectively. The same letters above the bars indicate no difference between the treatments at p < 0.05. Asterisk (*) and double asterisks (**) indicate p < 0.05 and p < 0.01, respectively, for Student’s t-test carried out between SaMR12 non-inoculated and SaMR12-inoculated samples
