Abiotic stress-induced ROS accumulation and MDA content were alleviated by exogenous melatonin in bermudagrass. (A–C) Quantifications of H₂O₂ content (A), O₂·^– content (B), and MDA content (C) of 28-day-old plants with different treatments (control and 20 μM melatonin) under control, 300mM NaCl, drought, and cold (4 °C) stress conditions on the designated days. The results shown are the means ±SEs, and bars with different letters above the columns of figures indicate significant differences at P<0.05 (Duncan’s range test).
