摘　　要：采用CIELAB表色系统研究了采收期、降温方法和套袋等处理对鸭梨采后果皮颜色变化的影响。结果表明,晚采收提高了鸭梨果实的成熟度和果皮的L、a、b(不套袋果)值,使得叶绿素减少,类胡萝卜素增加;缓降温处理促进了不套袋鸭梨L值和a值的升高,加速了叶绿素的降解,而对套袋果影响不明显;套袋处理使鸭梨的L值和a值增大,b值减小,叶绿素减少,颜色变浅,采后色泽的变化减缓。The effect of maturity, cooling method and bagging on the color changes of Yali pear after harvest using CIELAB color variables were studied. The results showed that late picking improved the maturity together with L, a and b （no-bagging fruits） value of Yali pear, decreased the chlorophyll content, and increased the carotenoid content of Yali pear. Slow cooling brought increases of L and a value and degradation of chlorophyll, but had not distinct influence on no-bagging fruit. Bagging treatment improved L and a value, decreased b value of Yali pear, decreased the chlorophyll content, made the peel color shallow, and slowed down the color change of the fruit peel.
