The ethylene action inhibitor 1-methylcyclopropene (1-MCP) reduces the rate of ripening of climacteric fruit including apple, pear and tomato. Several experiments using 1-MCP on non-climacteric fruit showed the same trend. Strawberries are non-climacteric fruit being high in value and highly perishable. ‘Jingnong 1st’ strawberry fruit were treated with 500 nl/L and 1000 nl/L 1-MCP. After 20 d at -1°C, fruit were placed on shelf at 4°C. The effect of 1-MCP on the rot rate and activity of antioxidant enzymes of fruits in shelf life was examined. Protein content of 1-MCP treated fruit increased and rot rate decreased 60% at the 8th day of shelf life. Superoxide dismutase (SOD) and catalase (CAT) activity of 1-MCP treated fruit were higher than control (not treated with 1-MCP), and were highest at 4th day and 3rd day of shelf life in fruit treated by 500 nl/L and 1000 nl/L 1-MCP, respectively. Asorbate peroxidase (APX) activities were significant higher than control and highest at 2nd day and 6th day in fruits treated with 500 nl/L and 1000 nl/L 1-MCP, respectively. Maintenance of these enzyme activities by 1-MCP during shelf life may potentially help in detoxification of active oxygen species generated during catabolic activities and maintain the quality of fruit longer.
