中文摘要: 采用不同的气体配比(O2 ∶CO2)处理西州密25 号哈密瓜,探讨4 ℃,相对湿度70%~75%条件下贮藏45 d 期间果实品质的变化规律。结果表明,西周密25 号哈密瓜的呼吸强度、乙烯释放速率、可滴定酸(total acid,TA)含量、可溶性固形物(total soluble solid,TSS)含量、多酚氧化酶(polyphenol oxidase,PPO)酶活、总糖及还原糖含量在贮藏过程中呈先上升后下降的趋势;维生素C 含量和硬度呈逐渐下降的趋势;而过氧化物酶(peroxidase,POD)酶活和丙二醛(malondialdehyde,MDA)含量呈逐渐上升的趋势。6%O2+1%CO2 和3%O2+1%CO2 两个处理的果实呼吸强度和乙烯释放速率均低于对照组,而TA、TSS、PPO、总糖及还原糖的含量均高于对照组;VC 含量、硬度、POD 酶活和MDA 含量变化速率比对照组变化缓慢。试验结果说明两种处理均有利于保持哈密瓜的贮藏品质,但是两种处理之间的差异却并不显著。总体来说,3%O2+1%CO2 处理的果实品质略高6%O2+1%CO2 处理,更有利于西周密25 号哈密瓜的贮藏保鲜。
