Changes in the levels of H2O2 accumulation and activities of ROS-scavenging enzymes in apple leaves under saline condition. a–h. H2O2 content, POD activity, CAT activity, SOD activity, APX activity, GR activity, AsA content, GSH content. Three-month-old seedlings of transgenic and WT plants were irrigated with 200 mM NaCl for 12 days, and the leaves were used for physiological analyses. Different letters indicate significant differences between treatments, according to Tukey’s multiple range tests (P<0.05)
