摘要: 库尔勒香梨果实褐变是贮藏中经常发生的一种生理病害,与酚类底物和多酚氧化酶(PPO)含量、分布有关,还与细胞膜结构变化密切相关。对库尔勒香梨果实褐变机理及防止措施进行了较深的研究,结果表明:在气调贮藏中,库尔勒香梨果实褐变指数与多酚氧化酶(PPO)含量成正相关,与酚类底物含量成负相关,与细胞膜相对电导率成正相关。

Abstract: The postharvest fruit browning of Pyrus bretschneideri Rehd was a Physiological disease in storage. It concerned not only the content and compartmentation of phenolics compounds and polyphenol oxidase but also the change of cell membrane structure. The browing mechanism and controlling methods of Pyrus bretschneideri Rehd were also researched in this discussion. The result indicated that the browning index of Pyrus bretschneideri Rehd was positively related to Polyphenol oxidase, negatively related to Phenolics compounds, positively related to the relative conductance rate in CA storage.
