【摘要】 对国产元帅、红星、新苹、青蕉、小国光等品种苹果采后及贮藏期间果实的呼吸、乙烯产生及硬度等进行了分析测定。结果表明大多数品种采后迅速后熟,呼吸跃变,很快发酥,品质变劣,其间乙烯大量产生,变化最为剧烈。贮藏保鲜效果好的各种处理都抑制或推迟了果实乙烯产生。果实中乙烯的浓度可以作为成熟状态的标示。通过不同时期采收,采后不同时间入库等处理果实生理变化及贮藏效果的比较看出,采后迅速控制后熟进程是提高贮藏质量,延长贮藏时间的关键。来后应用高CO₂,充氮、抽气等预处理对控制后熟有很好的效果。这些结果将为生产上改进贮藏工作,确定适宜采收期,提高贮藏质量等方面提供参考依据。更多还原

【Abstract】 The respiration rate, ethylene production and firmness of the apple fruit （Var.Red Delicious, Starkipg Delicious, Ben Davis, White Winter Pearmain, GoldenDelicious） were measured after harvest and during storage. It was found thatafter harvest the fruit ripened quickly, climacteric rise of respiration occurred,firmness and quality decreased, and above all, production of ethylene markedlyincreased. Treatment which depressed and or delayed the production of ethylenein fruit had a favorable effect on the keeping quality, it appeared that the produc-tion of ethylene in fruit was an indicator of ripeness. The results of experimentsof various harvesting date and various time intervals before storage showed thatto store the fruit as soon as it was harvested was of great importance for prolongingstorage period and improving fruit quality. Postharvest treatments with CO₂.N₂ and vacuum showed favorable results in the control of fruit ripening. These results may serve as the basis of improveing the storage quality of thefruit in practice.更多还原
