چکیده
this research was conducted to evaluate the effects of 1-mcp and ethylene on extending the display quality and increasing vase life of cut carnation flowers in a completely randomized design with three replicationsat the laboratory of the postharvest physiology, tarbiat modares universityin 2014. first, cut flowers were treated with 0, 0.5, 1 and 1.5 µl l-1 of 1-mcp for 24 h and then exposed to 1 µl l-1 ethylene for 16 h. the results showed that 1-mcp had significant effect on the physiological and biochemical characteristics and the activity of antioxidant enzymes. maximum of vase life and the amount of chlorophyll and anthocyanin were revealed in samples treated with 1 µl l-1 1-mcp. also, the highest peroxidase enzyme activity was observed in treatment of 1 µl l-1 1-mcp which had significant difference with other treatments. the highest and lowest catalase and superoxide dismutase activities were found in 1.5 µl l-1 1-mcp and control, respectively. in conclusion, 1-mcp treatment resulted in extending vase life and increasing activity of antioxidant enzymes in cut carnation cv. ‘grand slam’ by suppression of ethylene action.

Ethylene production is enhanced by wounding during fresh-cut processing and the accumulation of this gas within the packages of fresh-cut ruit can be detrimental to their quality and shelf-life. The effect of 1-methylcyclopropene (1-MCP), an ethylene action blocker, applied before r after processing, on the quality of fresh-cut kiwifruit, mangoes and persimmons was evaluated during storage at 5...
