The thicking of secondary cell wall may be one of the reason of ethanol accumulation. The activities peak value of CAT, PPO and POD were advanced and the activity of AAO gradually increased, the content of total phenol decreased sharply, the production rate of superoxide anion ,the content of MDA and H2O2 in flesh of 'brumal jujube' increased treated with ABA during storage, this showed ABA accelerated the scenescence of fruit, the effects of ABA on 'brumal jujube'fruit was contrary to GA.
点红冬枣贮藏过程中,各有机酸(柠檬酸、t-顺乌头酸、琥珀酸、延胡索酸)含量逐渐下降,苹果酸略有增加,丙酮酸含量逐渐增加,峰值出现后下降,说明丙酮酸的增加与进入三羧酸循环的有机酸流量的降低是导致果实乙醇发酵的机制之一;点红冬枣中蔗糖含量较高,贮藏期间,蔗糖含量下降,葡萄糖和果糖含量增加,气调贮藏可延缓果实蔗糖降解和葡萄糖和果糖含量的增加。
