1-MCP treatment can extend the shelf life and maintain the fruit quality of P. domestica fruit, while increasing the antioxidant activity.
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 degrees C 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 (O-2(center dot-)) of P. domestica fruit were all significantly reduced by 1-MCP treatment (1.0 mu L 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.
