this work was aimed to investigate the effect of 1-methylcyclopropene (1-mcp), ethylene absorber (ea), ozone alone or in combination on ethylene production, respiration rates, acoustic firmness, surface color, chlorophyll fluorescence parameters, and disease severity of melon. melons treated with 1-mcp at 5 °c were stored with sachets of ethyl stopper containing kmno4 (bioconservacion s.a., spain) or ozone at 0.1 ppm/h during 10 days at 5 °c and subsequent 4 days of shelf-life at 20 °c. samples treated with 1-mcp were firmer than the rest of the samples during storage. in addition, 1-mcp could slow the postharvest yellowing of melon rind compared to other treatments. the combination of 1-mcp and ea did not offer any additional effect in comparison with 1-mcp alone. ozone treatment during cold storage decreased disease severity, however, fruits exposed to ozone had more serious decay throughout shelf-life, probably due to the poor quality of air in the chamber. thus, the utilization of ozone in postharvest management and market environment should be considered for potential benefit.
研究了1-甲基环丙烯(1-mcp)、乙烯吸收剂(ea)、臭氧单独或联合使用对甜瓜乙烯产量、呼吸速率、声硬度、表面颜色、叶绿素荧光参数和病害严重程度的影响。在5℃下用1-mcp处理过的甜瓜，在5℃下10天和随后的4天保质期内，用含kmno4(bioconservicin s.a.，西班牙)或0.1ppm/h臭氧的乙基塞袋储存，在20℃下保存4天。用1-mcp处理过的样品比其他样品在储存期间更坚固。此外，与其他处理相比，1-mcp还可以减缓瓜皮的采后黄变。与单用1-mcp相比，单用1-mcp和ea的联合治疗没有提供任何额外的效果。冷藏期间的臭氧处理降低了疾病的严重程度，但是，在整个保质期内，暴露在臭氧中的水果有更严重的腐烂，这可能是由于贮藏室中的空气质量较差。因此，应考虑在收获后管理和市场环境中利用臭氧的潜在效益。

ethylene production.ethylene production was determined by an ica56 hand-held ethylene analyzer (international controlled atmosphere ltd., uk) upon the measured ethylene production of the samples being held for a given time (about an hour) in a hermetically closed plastic container. results were expressed in microliter of ethylene produced per kilogram of fruit in 1 h (μl·kg-1·h-1).
乙烯产量由一台ica56手持式乙烯分析仪(英国ica公司)根据在密封塑料容器中保存给定时间(约一小时)的样品的乙烯产量进行测定。结果以每公斤水果在1小时内产生的微升乙烯(μl·kg-1·h-1)表示。
