Prunus domestica L. cv. Ximei fruit perishes quickly due to intense metabolic activity after being harvested. To prolong shelf life and maintain fruit quality, the effects of 1-methylcyclopropene (1-MCP) treatment on P. domestica fruit during storage at 4 ± 1℃ were investigated. The results showed that the soluble solid content (SSC), respiratory rate (29.8%), ethylene production (27.2%), anthocyanin content, malonaldehyde content (MDA), hydrogen peroxide content (H₂O₂), and superoxide anion activity (O₂˙⁻) of P. domestica fruit were all significantly reduced by 1-MCP treatment (1.0 µL L⁻¹), while the content of ascorbic acid and total phenol, and the activity of SUPEROXIDE DISMUTASE (SOD, 61.3%), CATALASE (CAT, 39.0%), ASCORBATE PEROXIDASE (APX, 23.7%), and PEROXIDASE (POD, 38.0%) increased compared to untreated fruit after 35 days of cold storage. Overall, 1-MCP treatment could maintain high postharvest quality and antioxidant activity in P. domestica fruit.
