Effect of Preharvest Acetylsalicylic Acid and Postharvest 1-MCP Treatments on Quality and Antioxidant Ability of Muskmelon Fruit during Cool Storage
摘要
Abstract
This study examined effects of multiple preharvest acetylsalicylic acid (ASA) sprays combined with postharvest 1-methylcyclopropene (1-MCP) fumigation on the quality and antioxidant ability of muskmelon (Cucumis melo cv. Manao) fruit during cool storage. The plants were sprayed with ASA four times, namely at young fruit period (2 weeks after lfowering), fruit enlarging period (3 weeks after lfowering), netting period (4 weeks after lfowering) and 2 days before harvest, respectively. After harvest, the fruits were fumigated with 1-MCP. The results indicated that preharvest ASA treatment inhibited weight loss, retarded peel yellowing, maintained the levels of total soluble solids and titratable acid, increased the contents of total phenolics and lfavonoids, and enhanced the antioxidant ability of fruits. 1-MCP fumigation decreased weight loss, maintained fruit ifrmness and increased the contents of ascorbic acid. Preharvest ASA combined with postharvest 1-MCP treatments showed a synergistic effect on maintaining high levels of total soluble solids and titratable acid and enhancing the contents of total phenolics and lfavonoids. In conclusion, ASA and 1-MCP treatments maintained the postharvest quality of muskmelons, which is related to the inhibition of ethylene production. Both chemicals enhanced the antioxidant activity of fruits, which are involved in the accumulation of phenylpropanoid metabolites and ascorbic acid.关键词
