摘要
研究了苹果梨贮藏期生理生化变化。结果表明，低温可明显延迟成熟中的多种变化。苹果梨呼吸强度很低，在２～１０ｍｇＣＯ２（ｋｇｈ）－１。低温贮藏后期呼吸强度只有２～３ｍｇＣＯ２（ｋｇｈ）－１。苹果梨乙烯释放量极低，在０～０．５μｌ（ｋｇｈ）－１之间。乙烯在苹果梨后熟中起重要作用，影响着多种物质的变化。苹果梨在贮藏期能保持其硬度和Ｖｃ的水平。
This experiment studied physiological and bio-chemical changes of Pingguo pear
durint storage period.The result showed that low temperature obviously delayed many changes
during maturity.Its respiration intensity was very low,within 210 mg CO2/kgh and only 23 mg
CO2/kgh during later storage period.The ethylene production of Pingguo pear was extremely
low,less than 0.5 L/kgh.Ethylene acted importantly on Pingguo pear after ripening,affected
changes of many substances.Pingguo pear could preserve its hardness and vitamin C content
during storage time.
