| Strawberries are characterized by their delicate skin, making them highly susceptible to mechanical damage and pathogen infection. This poses significant challenges to their preservation. Consequently, the development of effective strawberry preservation technologies is of great significance. In recent years, the role of melatonin in regulating fruit development and enhancing postharvest preservation has gained significant attention. This study aimed to evaluate the preservation effects of melatonin solutions at different concentrations on strawberries (Fragaria ananassa Duch.). Two strawberry cultivars, ‘Zhangji’ and ‘Hongyan’ were selected and treated with melatonin solutions at concentrations of 0.1 mmol/L, 0.3 mmol/L, and 0.5 mmol/L. Key parameters such as rot rate, weight loss rate, firmness, soluble solids content, titratable acidity, and vitamin C content were measured following melatonin treatment. The results showed that the optimal melatonin concentrations for preserving ‘Zhangji’ and ‘Hongyan’ strawberries were 0.5 mmol/L and 0.3 mmol/L, respectively. |
