【摘要】 为了研究贮藏温度对大果水晶梨采后生理生化变化的影响,以大果水晶梨为试材,在(1±0.5)℃,(3±0.5)℃,(5±0.5)℃和室温(16~22)℃条件下进行了贮藏试验。结果表明,大果水晶梨在(1±0.5)℃下贮藏时无明显的呼吸高峰,且乙烯释放速率较低;果实营养物质的消耗和色素的降解较慢,果胶酶、淀粉酶活性被抑制,梨果贮藏保鲜效果明显改善。用聚乙烯薄膜打孔袋包装后,大果水晶梨在室温下能贮藏105 d,在(5±0.5)℃时能贮藏180 d,在(1±0.5)℃和(3±0.5)℃下贮藏180 d时品质良好。以上各项指标显示,大果水晶梨在(1±0.5)℃下的冷藏效果最好。更多还原

【Abstract】 In order to study the effect of different storage temperature on post-harvest physiology in suisho pear,suisho pears are storaged at temperatures of(1±0.5) ℃,(3±0.5) ℃,(5±0.5) ℃ and room temperature(16～22 ℃).The results indicate that the ethylene release rate is lower and no apparent peak respiration at temperatures of(1±0.5) ℃;at temperatures of(1±0.5) ℃ the loss of nutrition substance and decomposition of pigments decreased,and the activities of amylase and PG are inhibited and the effect of storage and keeping-fresh is obviously improved.Polyethylene(PE) film bag with hole storage could keep 105 days at room temperature,and 180 days at temperatures of (5±0.5) ℃,and the quality is good at temperatures of(1±0.5) ℃ and(3±0.5) ℃ at the same days.Each target demonstrates that the optimum environment of storage for suisho pear is at temperatures of(1±0.5) ℃.更多还原
