From: Comparative physiological and full-length transcriptome analyses reveal the molecular mechanism of melatonin-mediated salt tolerance in okra (Abelmoschus esculentus L.)

Effects of 50 μM melatonin pretreatment on enzymatic activity of peroxidase (POD) (a), catalase (CAT) (b), superoxide dismutase (SOD) (c), and glutathione reductase (GR) (d) in the second leaf of okra exposed for 7 d either to salt stress (by irrigating with 300 mM NaCl) or to optimum conditions. Data are means ± SD of four replicates. Bars with different letters are significantly different according to Duncan’s multiple range tests (P < .05). Mock, pretreatment with water and grown under optimum conditions; NaCl, pretreatment with water and subsequently subjected to salt stress; MT, pretreatment with 50 μM melatonin and grown under optimum conditions; MT + NaCl, pretreatment with 50 μM melatonin and subsequently subjected to salt stress
