摘要: The effects of 1-methylcyclopropene (1-MCP) treatments on the several physiological characteristics of 'Bayuehong' (Pyrus bretschneideri Rehd. x Pyrus communi) pears during storage were studied. 1-MCP applications inhibited respiration rate, relative conductivity and polyphenol oxidase activity of 'Bayuehong' pears at both 0 degrees C and at ambient temperature during storage. 1-MCP treatments also increased postharvest peroxidase activity. 1-MCP was very effective in preventing development of skin blackening (a symptom like superficial scald of apples) and core browning. 1-MCP treatment delayed loss of firmness, soluble solids and titratable acidity both at ambient temperature and 0 degrees C. These results indicated that 1-MCP could delay fruit ripening, and improve storage quality significantly.
