Figure 1

The effect of ME treatment at four different concentrations on (CI-index), water loss% and fruit peel colour (h°) of ‘Washington’ navel orange fruits during cold storage at (4 ± 1 °C and 95 ± 1% RH) for (4 weeks). The vertical bars represent standard error (±SE of n = 3) and the alphabetical letters pointed to the significance at p = 0.05 between treatments in each storage period. The average of both experimental seasons (2019 and 2020) was analysed by using Duncan's Multiple Range Test. CI, chilling injury; ME, melatonin.

The effect of ME treatment at four different concentrations on (SSC%), (TA%), and SSC/TA-ratio of ‘Washington’ navel orange fruits during cold storage at (4 ± 1°C and 95 ± 1% RH) for (4 weeks). The vertical bars represent standard error (±SE of n = 3) and the alphabetical letters pointed to the significance at p ≤ 0.05 between treatments in each storage period. The average of both experimental seasons (2019 and 2020) was analysed by using Duncan's Multiple Range Test. ME, melatonin; SSC%, soluble solid content; TA%, total acidity.

The effect of ME treatment at four different concentrations on AEAs of ‘Washington’ navel orange during cold storage at (4 ± 1°C and 95 ± 1% RH) for (4 weeks). The vertical bars represent standard error (±SE of n = 3) and the alphabetical letters pointed to the significance at p ≤ 0.05 between treatments in each storage period.

The effect of ME treatment at four different concentrations on the MDA accumulation (μM · g−1 FW), (IL%), AA content (mg · 100 g−1 FW) of ‘Washington’ navel orange during cold storage at (4 ± 1°C and 95 ± 1% RH) for (4 weeks). The vertical bars represent the standard error (±SE of n = 3) and the alphabetical letters pointed out the significance at p ≤ 0.05 between treatments in each storage period. The values are the average of both tested seasons (2019 and 2020) was analysed by using Duncan's Multiple Range Test. MDA, malondialdehyde; ME, melatonin.
