摘要: 采用聚乙烯醇（PVOH）、聚对苯二甲酸乙二醇酯（PET）、聚丙烯（PP）3种包装材料在同一气调比例下对新疆厚皮甜瓜进行贮藏实验,每10 d使用液相氧电极仪测定不同呼吸途径:糖酵解（EMP）、三羧酸循环（TCA）、戊糖磷酸途径（PPP）、细胞色素系统途径（CP）、交替途径（AP）、总呼吸（Total）的呼吸速率;采后第70 d统计各处理组甜瓜的腐烂率、好果率情况。结果表明:在贮藏温度为（3±1）℃,相对湿度为75%85%条件下,甜瓜装入三种包装材料膜内充入O2、CO2浓度分别约为5.59%、1.80%后与CK相比较,采后各处理组总呼吸途径速率均得到有效抑制,其中PP处理组采后各呼吸速率均小于其它三组,EMP路径呼吸速率受环境影响转移到以TCA路径为主。至贮期结束后,PP包装膜处理的甜瓜贮藏品质相对最好,可以有效降低呼吸速率、延缓甜瓜的成熟衰老、防止病害的发生;CK贮藏效果最差。Abstract: The storage experiments of Cucumis melo L.were carried out under the same air-conditioning ratio used 3 different packaging materials of polyvinyl alcohol ( PVOH) , polyethylene terephthalate ( PET) and polypropylene ( PP) . Different respiratory pathways were measured by liquid oxygen electrode every 10 days, including the respiration rate of glycolysis ( EMP) , tricarboxylic acid cycle ( TCA) , pentose phosphate pathway ( PPP) , cytochrome pathway ( CP) , alternative pathway ( AP) , total respiration ( Total) . On the 70 th day after harvest, the decay rate and fruit rate of each treatment group were analyzed.The results showed that the storage temperature was ( 3 ± 1) ℃ and the relative humidity was 75% ~ 85%. The concentrations of O2 and CO2 in the 3 kinds of package materials were about 5.59% and 1.80% and then compared with CK.The total respiratory rate of each treatment group was effectively inhibited.As the respiration rate of PP treatment group was less than that of other three groups, and the respiratory pathway of the EMP was affected by environment and shifted to the TCA.At the end of the storage, PP package treatment of melon storage quality was relatively best, which could effectively reduce the respiratory rate, delay the maturity, prevent the occurrence of disease and senescence.The quality of CK was worst.
