“…These changes are crucial because of their role in scavenging oxygen free radicals and reactive oxygen species. Many studies have demonstrated that regulating the antioxidant system eliminates excessive ROS accumulation and induces chilling tolerance in postharvest fruit and vegetables [30,31].…”

Currently, several studies have demonstrated that cold stress can cause the accumulation of reactive oxygen species (ROS) in fruit. However, little is known about the roles of gibberellic acid (GA3) on the antioxidant system in the mitochondria of fruit. To explore the molecular basis of GA3 interference with the chilling tolerance of fruit, ‘Jinqiuhongmi’ peach fruit was treated with 0.1 mmol L−1 GA3 after harvest. Exogenous GA3 treatment relieved the chilling injury of postharvest peach fruit with a lower cold injury index and higher antioxidant level. In addition, GA3 delayed the senescence of peaches by reducing the firmness, respiratory action, and ethylene production. The antioxidant enzyme activities were elevated, including superoxide dismutase (SOD) and catalase (CAT). Moreover, GA3-treated peaches exhibited lower hydrogen peroxide (H2O2) and malondialdehyde (MDA) in comparison with the control. These results showed that the application of 0.1 mmol L−1 of GA3 enhanced the chilling resistance of peach fruit by regulating the antioxidant system.

“…For plant tissues, an adequate energy supply is vital for the proper functioning of many physiological metabolisms. The activation of energy metabolism effectively enhances the fruit storability including mango ( Huang et al, 2024 ), papaya ( Zhou et al, 2024 ) and fig. ( Wang, Jing et al, 2024 ).…”

BACKGROUNDPostharvest mango fruit are highly susceptible to rapid ripening, softening and senescence, greatly limiting their distribution. In this study, we evaluated the potential effects of carvacrol (0.06 g L−1) on mango (25 ± 1 °C) and the mechanisms by which it regulates antioxidant activity, energy and cell wall metabolism.RESULTSThe results showed that carvacrol treatment delayed the ‘Guifei’ mango color transformation (from green to yellow) and the decrease in firmness, titratable acidity, weight loss and soluble solids content, and suppressed the increase in relative conductivity, malondialdehyde content and reactive oxygen species (H2O2 and O2·–) as well as enhancing antioxidant activity. In addition, carvacrol treatment increased ascorbic acid and reduced glutathione levels, ascorbate peroxidase, glutathione reductase, monodehydroascorbate reductase and dehydroascorbate reductase activities in mango. Meanwhile, energy level (adenosine triphosphate, adenosine diphosphate, adenosine monophosphate and energy charge) content and energy metabolizing enzyme activities (H+‐ATPase, Ca2+‐ATPase, succinate dehydrogenasepears and cytochrome C oxidase) were increased on carvacrol treatment, which resulted in the maintenance of higher energy levels. Finally, the application of carvacrol was effective in maintaining firmness and cell wall components by inhibiting the activities of polygalacturonase, cellulase, pectin methyl esterase and β‐galactosidase.CONCLUSIONThe current study demonstrates that carvacrol effectively delays the ripening and softening of mangoes by modulating energy metabolism and cell wall dynamics through the attenuation of oxidative stress. © 2024 Society of Chemical Industry.
