“…These findings were in agreement with previous studies on the green bell peppers (Kong et al, 2020), litchi fruits (Zhang et al, 2018), and plum fruits (Bal, 2019) treated with MT. Similar results were found by Jiang et al (Liu et al, 2015), whose research showed that 1-MCP fumigation retained FF, TSS, TA, and ASA and postponed the onset of the maximum of antioxidant activity, proved a good practice for maintaining peach fruit quality.…”

The effect of melatonin (MT) dipping and 1-methylcyclopropene (1-MCP) fumigation either individually or combined, on reducing delaying fruit senescence in apricot fruit was investigated. The results showed that the individual and combined MT and 1-MCP treatments maintained the quality of apricot fruits after harvest and reduced fruit softening, rot, and weight loss. This was mainly attributed to the high levels of ascorbic acid content, total phenol content, and total flavonoid content, as well as the upregulation of peroxidase, superoxide dismutase, and catalase enzyme activities, which reduced the active oxygen content. Besides, 1-MCP and MT in individual or in combined treatments suppressed the process of membrane lipid peroxidation by inhibiting the malondialdehyde content and lipoxygenase activities, contributing to delaying the senescence of apricot fruits. Among these three treatments, 1-MCP was the best method to delay the postharvest senescence of apricots. Novelty impact statement: The individual and combined MT and 1-MCP treatments had positive effect on apricot fruits quality during cold storage. The individual and combined MT and 1-MCP treatments apparently enhanced the activity of enzymatic antioxidants and nonenzymatic antioxidants. Decreased H 2 O 2 generation was observed in the individual and combined MT-and 1-MCP-treated fruits during storage time.

“…The lower weight losses observed in fruits from melatonin treated trees with respect to those of controls might be attributed to an effect of melatonin on increasing cuticle thickness, as recently proposed for nectarines [29] and mangos [30] after postharvest melatonin treatment. Accordingly, postharvest 0.1 mM melatonin treatment delayed the postharvest ripening process during cold storage in apples [31], peaches [32], nectarines [29], pears [33], and mangos [34], which was attributed to a inhibition of ethylene production, although similar effects have been reported in non-climacteric fruits such as sweet cherries [35].…”

Melatonin Treatment of Pomegranate Trees Increases Crop Yield and Quality Parameters at Harvest and during Storage

et al. 2021

With the aim to study the effect of melatonin treatment of pomegranate trees on crop yield and fruit quality at harvest and during storage, two experiments were carried out in two consecutive years: 2017 and 2018. In the first year, trees were treated with melatonin (at 0.1 and 1 mM) along the developmental growth cycle and fruit quality parameters were evaluated at harvest and during storage at 10 °C for 90 days. Treatments with melatonin led to an increase of crop yield (number of fruits per tree and kg per tree), as well as higher fruit quality attributes, such as fruit size (diameter and weight), color, total soluble solids (TSS), and total acidity (TA), especially with the 0.1 mM dose. Then, in the second year, melatonin at 0.1 mM was selected for repeating the pre-harvest treatments with similar results in terms of crop yield and fruit quality parameters. During storage, pomegranate fruit treated with 0.1 mM melatonin maintained higher quality attributes than controls, such as TSS, TA, and firmness and lower weight losses were observed in fruit from treated trees, in both trials. In addition, the content of the major sugars (glucose and fructose) and organic acids (malic, succinic and ascorbic acid) were higher in melatonin-treated than in non-treated fruit. These results suggest that pre-harvest melatonin treatment could be a useful tool to increase pomegranate crop yield as well as fruit quality parameters at harvest and their maintenance during storage due to an effect of melatonin on reducing the postharvest ripening process.

“…However, the effects of melatonin postharvest treatments on increasing fruit bioactive compounds and antioxidant activity have been addressed in more fruit species. 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 ].…”

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

et al. 2021

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.
