(a) Superoxide dismutase (SOD), (b) catalase (CAT), and (c) lipoxygenase (LOX) activities of mango cv. “Dashehari” treated with melatonin (MT), followed by low-temperature storage at 5 ± 1°C. Measurements were taken every 7 d of storage, followed by a 3 d of shelf life at room temperature. Each value is the mean of three replicates; vertical bars indicate the standard error. Different lowercase letters on the same storage period indicate a significant difference () according to Duncan’s multiple range test. The abbreviated treatment details: 0 (control), 50 µM for 90 min (T1), 50 µM for 120 min (T2), 50 µM for 150 min (T3), 100 µM for 90 min (T4), 100 µM for 120 min (T5), 100 µM for 150 min (T6), 150 µM for 90 min (T7), 150 µM for 120 min (T8), and 150 µM for 150 min (T9).
