“…On the other hand, in climacteric fruit, such as ‘Colorado’ and ‘Mikado’ apricot, an effect of 0.1 mM melatonin treatments on delaying the postharvest ripening process at 1 and 8 °C has been observed recently, which was attributed to a reduced ethylene production in both cultivars and both storage temperatures [ 54 ]. Similar effects were observed by postharvest melatonin treatments on mangoes [ 26 ], banana [ 27 ], peaches [ 28 ], nectarines [ 29 ], apples [ 55 ] and pears [ 56 ], which were attributed to a reduced expression of genes codifying for ACC-synthase and ACC-oxidase. However, pomegranate is a non-climacteric fruit and ethylene production was very low in all fruit during storage, irrespective of treatments (data not shown).…”

“…Accordingly, melatonin postharvest treatment inhibited ethylene production and delayed ripening in banana fruit [ 27 ], which were dose-dependent in the range of 0.05 to 0.5 mM. Similar results have been reported in peaches and nectarines [ 28 , 29 ]. In tomato fruit, postharvest treatment with melatonin at 50 µM increased anthocyanin content.…”

“…For instance, in ‘Santa Rosa’ plum, postharvest dipping treatment with 0.1 mM melatonin led to higher ascorbic acid, total phenolics and antioxidant activity levels during storage as compared with controls [ 42 ], as well as on strawberry treated with 0.1 or 1 mM of melatonin [ 43 ]. In addition, dipping treatment of nectarine fruit with 0.25, 0.5 and 1 mM of melatonin for 30 min and of peach fruit with 0.1 mM for 10 min minimised phenolic losses during storage at 1 °C [ 29 , 44 ]. Accordingly, 0.1 mM melatonin dipping treatment of sweet cherry increased anthocyanin content during storage due to an induced overexpression of two key genes coding for dihydroflavonol 4-reductase (DFR) and anthocyanidin 3- O -glucosyltransferase (UFGT), which are enzymes involved in the last steps of anthocyanin biosynthesis [ 45 ].…”

“…However, pomegranate is a non-climacteric fruit and ethylene production was very low in all fruit during storage, irrespective of treatments (data not shown). Accordingly, postharvest melatonin treatment also delayed the postharvest ripening process in non-climacteric fruits, such as sweet cherry [ 29 ], which was not mediated by reduction in ethylene production.…”

The effect of melatonin pomegranate tree treatments on fruit quality and bioactive compounds with antioxidant activity at harvest and during storage at 10 °C for 60 days was assayed in two consecutive years, 2019 and 2020. In the first year, trees were treated with 0.1, 0.3 and 0.5 mM of melatonin along the developmental fruit growth cycle, and results showed that bioactive compounds (total phenolics and total and individual anthocyanins) and antioxidant activity at harvest were higher in fruits from melatonin-treated trees than in controls. Other fruit quality parameters, such as firmness, total soluble solids and aril red colour, were also increased as a consequence of melatonin treatment. In fruit from control tress, firmness and acidity levels decreased during storage, while increases occurred on total soluble solids, leading to fruit quality reductions. These changes were delayed, and even maintenance of total acidity was observed, in fruit from melatonin-treated trees with respect to controls, resulting in a fruit shelf-life increase. Moreover, concentration of phenolics and anthocyanins and antioxidant activity were maintained at higher levels in treated than in control fruits during the whole storage period. In general, all the mentioned effects were found at the highest level with the 0.1 mM melatonin dose, and then it was selected for repeating the experiment in the second year and results of the first year were confirmed. Thus, 0.1 mM melatonin treatment could be a useful tool to enhance aril content on bioactive compounds with antioxidant activity and health beneficial effects and to improve quality traits of pomegranate fruit, at harvest and during postharvest storage.

“…Accordingly, Cyn 3-rut was the major anthocyanin in the 'Ferrovia' cultivar, although cyanidin 3-O-galactoside and Cyn 3-gluc were the minor ones [21]. Postharvest melatonin treatments have shown a general trend on increasing phenolic content, including anthocyanins, and antioxidant activity in a wide range of fruit species, such as 'Santa Rosa' plum [44], strawberry [45], nectarine [46], tomato [17], litchi [47] and pomegranate [48]. Accordingly, preharvest treatment of pomegranate trees led to enhanced concentrations of total phenolics and total and individual anthocyanins as well as of total antioxidant activity in arils at harvest, showing that melatonin treatment stimulated the anthocyanin biosynthesis pathway [16].…”

Effects of Melatonin Treatment on Sweet Cherry Tree Yield and Fruit Quality

The effects of preharvest melatonin treatment, applied as foliar spray at 0.1, 0.3 and 0.5 mM concentration at three key points of fruit development (pit hardening, initial colour changes and 3 days before harvesting), on crop yield and fruit quality properties at harvest was evaluated in three sweet cherry cultivars, ‘Prime Giant’, ‘Lapins’ and ‘Sweet Heart’, and two years, 2019 and 2020. The results showed that melatonin treatment had no effect on crop yield, except for the ‘Lapins’ cultivar, in which increases were found. However, decayed and cracked fruit percentage was decreased in all cultivars in 2020 when adverse weather conditions occurred and commercial crop yield was increased, especially for 0.3 mM dose. Fruit quality traits at harvest, such as fruit weight, colour, firmness, total soluble solids and titratable acidity, were enhanced by melatonin treatments in all sweet cherry cultivars and in both years. Moreover, bioactive compounds, such as total phenolics and total and individual anthocyanins, were also found at higher levels in fruit from melatonin-treated trees with respect to controls. Thus, taking into account all these effects, 0.3 mM melatonin foliar spray, at three key points of fruit developmental stages, could be a useful tool to improve crop yield and quality traits of sweet cherries, especially their content on bioactive compounds with antioxidant properties and health beneficial effects.

The best strategy to extend the shelf life of fresh horticultural produce is to keep it at a low temperature. However, storing fruits and vegetables at a temperature lower than their recommended storage temperature and above the freezing point for a prolonged time leads to the development of chilling injury (CI). Melatonin (MT) being a versatile biological signal has been reported to possess antioxidant properties that aid in mediating stress response and extending the postharvest storage life of horticultural crops. Among CI‐induced mechanisms, MT substantially reduces oxidative stress by elevating the reactive oxygen species scavenging and triggering the phenol accumulation in association with 2, 2‐diphenyl‐1 picryl hydrazyl scavenging activity. Besides, MT increases intracellular energy by maintaining a proper ratio of unsaturated to saturated fatty acid and improving cellular fluidity. Additionally, MT regulates arginine metabolism by maintaining the γ‐aminobutyric acid synthesis. Furthermore, MT encodes the mitogen‐activated protein kinases, and calcium‐dependent protein kinases cascade and acclimate to cold stress by activating C‐repeat binding factors and helps in maintaining postharvest quality. This review reports the recent progress of MT‐induced physiological, biochemical, and molecular mechanisms for enhancing chilling tolerance, which can elevate the marketability and earnings from postharvest horticultural crops.
