摘　　要：为了研究运输过程中振动对哈密瓜贮藏品质的影响,试验模拟半挂车运输振动环境,比较经振动处理与未经振动处理哈密瓜在室温(23℃)贮藏期间(28d)品质的变化情况。研究结果表明:贮藏28d时,振动后的哈密瓜呼吸速率高于对照组,说明振动会加快哈密瓜的呼吸速率及后熟作用,加速衰老及硬度下降速率,加快丙二醛产生及哈密瓜细胞膜脂的氧化,从而破坏细胞膜完整性,最终加快哈密瓜的衰老腐败。In order to study the effect of transport vibration on storage quality of Hami melons （Cucumis melo vat. saccharinus）, transport vi- bration of semi-trailer was simulated. The melons treated by transport vi- bration was compared with the untreated melons while melons were stored 28 d at room temperature （23℃）. The result showed that： when stored at 28 d, respiration rate of vibration-treated melons was higher than un- treated, it was indicated that the transport vibration will accelerate respi- ration rate and after-ripening, accelerate aging, and the rate of decrease in hardness, speed up the generation of MDA and membrane lipid oxidation. thereby the integrity of the ceil membrane was undermined, and ultimate- ly accelerate the aging corruption of melons.
