摘要

'Formosa' plums were picked at three maturity stages according to skin redness, treated with 1 mu L-L~(-1) 1-MCP at 10°C for 24 h and then stored for 21 days at 10°C. Ethylene production, respiration rate, firmness, color, TSS, TA, and ethanol concentration were determined. Total phenolic content, total flavonoid content, and antioxidant capacity were determined periodically by separating the flesh from the peel. Ethylene production and respiration rate were strongly inhibited in all stages of the1-MCP-treated fruit, while ethylene production dramatically increased in all stages of non-treated fruit until 11 days after harvest, after which it decreased until the end of the experiment. The respiration rate of the stored fruit increased for 11 daysin stages 1 and 2 and for 7 days in stage 3 and decreased after. 1-MCP-treated fruit in all stages showed delay in fruit quality changes such as firmness, TA, skin color, and ethanol concentration, but non-treated fruit did not. Total phenolic contents,total flavonoid contents and antioxidant capacity of 'Formosa' plums were not affected by 1-MCP treatment or maturity stage. However, those values were higher in the peel than in the flesh.
