Plant Growth-Promoting Rhizobacteria Enhance Salinity Stress Tolerance in Okra through ROS-Scavenging Enzymes

Figure 3

Effect of PGPR inoculation on antioxidant enzymes activities in okra leaves under salt stress. T0: noninoculated salt treated plants, T1: UPMR2 inoculated salt treated plants, T2: UPMR18 inoculated salt treated plants, and T3: both UPMR2 and UPMR18 inoculated salt treated plants. Error bars refer to standard error of means of four replicates. APX: ascorbate peroxidase, CAT: catalase, and SOD: superoxide dismutase. Means within columns with the same letters are not significantly different at .
