摘　　要：以藁城、黄骅、沾化冬枣为试材,研究了不同产地冬枣采后贮藏过程中的品质变化。试验结果表明,藁城、黄骅、沾化冬枣的冰点分别为-3.5℃、-4.2℃、-3.9℃;在0℃贮藏条件下,随着贮藏时间的延长,不同产地冬枣硬度均随着贮藏期的延长而下降,VC含量逐渐减少,可滴定酸含量在贮藏过程中整体上呈下降趋势,沾化冬枣酸含量最高,藁城冬枣还原糖含量最小,在贮藏过程中变化较大。贮藏结束后各地冬枣硬度差异极显著(P<0.01),VC含量差异显著(0.01<P<0.05),可滴定酸含量差异极显著(P<0.01),还原糖含量差异极显著(P<0.01);黄骅地区土壤中平衡的氮、磷、钾配比,适宜的气候条件,导致黄骅冬枣耐贮性优于藁城、沾化冬枣。In this paper, changes in quality were studied of fresh Dongzao jujube in different producing areas during storaged. The effects showed that the freezing points were -3.5 ℃（Gaocheng）, -4.2 ℃（Huanghua） and -3.9 ℃ （Zhanhua）;In 0 ℃ condition, with the storage time,the firmness of Dongzao jujube from different producing areas reduce gradually,VC and titratable acid content decreased constantly,reducing sugar content increases gradually. At the end of storage, VC content diversity in different producing areas was marked. Firmness diversity, titratable acid and reducing sugar contents diversity were much marked. With good proportion of N,P,K and fitting weather quality changes of Dongzao jujube in Huanghua were better than in Gaocheng and Zhanhua.
