为了探明猕猴桃果实贮藏期间品质与生理生化变化特点及影响其贮藏性能的主要因子,以不耐贮藏的中华猕猴桃"丰悦"和耐贮藏的美味猕猴桃"沁香"为试材,采用提高果实耐贮性处理,以喷施清水为对照,测定两种处理下贮藏期间果实生理生化指标的变化,运用主成分分析法,构建综合评价指标F值。结果表明,贮藏期间果实Vc、果肉硬度和可滴定酸的含量变化是反映果实品质变化特征的主要因子,乙烯释放量、呼吸作用和淀粉酶活性的变化是反映果实生理生化的变化特征的主要因子;通过分析综合评价指标的F值发现,其主要因子特征值累计百分率大于85%,该统计方法可客观准确反映猕猴桃果实后熟过程中生理生化的变化。不同猕猴桃品种、不同耐贮性的猕猴桃果实,在贮藏过程中其品质和生理生化变化特点具有统一性。
為瞭探明獼猴桃果實貯藏期間品質與生理生化變化特點及影響其貯藏性能的主要因子,以不耐貯藏的中華獼猴桃"豐悅"和耐貯藏的美味獼猴桃"沁香"為試材,採用提高果實耐貯性處理,以噴施清水為對照,測定兩種處理下貯藏期間果實生理生化指標的變化,運用主成分分析法,構建綜閤評價指標F值。結果錶明,貯藏期間果實Vc、果肉硬度和可滴定痠的含量變化是反映果實品質變化特徵的主要因子,乙烯釋放量、呼吸作用和澱粉酶活性的變化是反映果實生理生化的變化特徵的主要因子;通過分析綜閤評價指標的F值髮現,其主要因子特徵值纍計百分率大于85%,該統計方法可客觀準確反映獼猴桃果實後熟過程中生理生化的變化。不同獼猴桃品種、不同耐貯性的獼猴桃果實,在貯藏過程中其品質和生理生化變化特點具有統一性。

In order to understand the changes in quality and physiology of kiwifruit during storage as well as the main factors influencing the storage performance of kiwifruit, the Chinese kiwifruit variety "Fengyue", which has bad storability, and delicious kiwifruit variety "Qingxiang", which has good storability, were taken as test materials to determine the changes in physiological indexes of kiwifruit during storage under treatment of enhancing fruit storability and treatment of spraying water, respectively; then using principal component analysis method to construct comprehensive evaluation indicator F-value. The results showed that during storage, the changes in contents of fruit Vc, soluble solids, and titratable acid were the main factors reflecting fruit quality changes, and the changes in ethylene release rate, respiration and amylase activity were the main factors reflecting fruit physiological changes; the cumulative percentage of main factor characteristic value was greater than 85% through analyzing the F-value. Therefore, the physiological changes of kiwifruit during after-ripening can be accurately reflected by the statistical method. Moreover, the kiwifruits with different varieties or different storabilities have uniformity in quality changes and physiological changes during storage.
