“…The application of melatonin also significantly increased the activities of CAT, SOD and POD in apple fruits, improving the antioxidant capacity of the fruit and maintaining its quality [22]. Nonenzymatic antioxidants, such as phenolics, GSH, AsA, flavonoids and anthocyanins, were also effectively induced by melatonin treatment [14,35,37]. The exogenous application of melatonin increased the polyphenol content and antioxidant activities in grapes [46].…”

“…Fruit have evolved efficient non-enzymatic and enzymatic antioxidative systems to scavenge ROS and protect against oxidative damage [40]. The antioxidant enzymes, including CAT, APX, polyphenol oxidase (PPO), peroxidase (POD), dehydroascorbate reductase, SOD, GR and GPX, are important for ROS homeostasis in fruit [14]. The non-enzymatic antioxidants include ascorbic acid (AsA), flavonoids, anthocyanins, phenolics, carotenoids, dehydroascorbic acid and glutathione (GSH) [14,41].…”

“…Melatonin (N-acetyl-5-methoxytryptamine) is a multifunctional signaling molecule that is ubiquitously distributed in various plant species [14]. Melatonin is involved in various physiological activities in plants, including seed and root development [15], plant growth and flowering [16], fruit development [17], fruit ripening [18], senescence [19] and biotic and abiotic stress responses [20,21].…”

Guava fruit has a short postharvest shelf life at room temperature. Melatonin is widely used for preservation of various postharvest fruit and vegetables. In this study, an optimal melatonin treatment (600 μmol·L−1, 2 h) was identified, which effectively delayed fruit softening and reduced the incidence of anthracnose on guava fruit. Melatonin effectively enhanced the antioxidant capacity and reduced the oxidative damage to the fruit by reducing the contents of superoxide anions, hydrogen peroxide and malondialdehyde; improving the overall antioxidant capacity and enhancing the enzymatic antioxidants and non-enzymatic antioxidants. Melatonin significantly enhanced the activities of catalase, superoxide dismutase, ascorbate peroxidase and glutathione reductase. The contents of total flavonoids and ascorbic acid were maintained by melatonin. This treatment also enhanced the defense-related enzymatic activities of chitinase and phenylpropanoid pathway enzymes, including phenylalanine ammonia lyase and 4-coumaric acid-CoA-ligase. The activities of lipase, lipoxygenase and phospholipase D related to lipid metabolism were repressed by melatonin. These results showed that exogenous melatonin can maintain the quality of guava fruit and enhance its resistance to disease by improving the antioxidant and defense systems of the fruit.

“…No previous reports are available regarding the effects of preharvest melatonin treatments on delaying fruit ripening and maintaining fruit quality attributes during storage for comparative purposes. However, postharvest dipping treatments have been reported to maintain fruit quality traits and extend shelf-life in several fruit species, such as banana, peach, pear, kiwi or strawberry, and even in pomegranate, as recently revised by Ze et al [ 53 ], although the applied dose and time dipping was different for each fruit species. These effects were attributed to a reduced accumulation of reactive oxygen species (ROS) due to increases in the enzymatic activities and gene expressions of antioxidant enzymes.…”

Melatonin Treatment to Pomegranate Trees Enhances Fruit Bioactive Compounds and Quality Traits at Harvest and during Postharvest Storage

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.

Low‐temperature storage of fresh fruits and vegetables, especially below the critical storage temperatures, leads to chilling injury that makes the produce unsuitable for market use. Postharvest application of melatonin for chilling injury alleviation in fruits and vegetables is an alternative preventive measure for the longer persistence of fresh produce on the market. This review classified the mechanisms involved in melatonin‐mediated chilling tolerance into physiological, biochemical (sugar metabolism, organic acids, lignification and respiratory modulation, ripening, senescence, membrane structure, maintenance of the antioxidant system, endogenous proline, endogenous polyamine, γ‐amino butyric acid shunt pathway, and modulation of energy status), and hormonal (ethylene, indole acetic acid, jasmonic acid, and abscisic acid regulation) pathways. Melatonin acted via several mechanisms, including antioxidant activity elevation, induction of antioxidant enzymes, gene expression regulation, gamma‐aminobutyric acid shunt pathway, induction of stress‐tolerant proteins, and cell membrane stabilization. However, dose and duration of exposure optimization, along with alternative means for mass production of melatonin, is required to promote trails.
