摘　　要：以陕西省延安市延川县延水关镇采摘的25个鲜枣为试材,测定了不同品种鲜枣中过氧化氢酶活性的大小,旨在研究鲜枣中过氧化氢酶活性对枣抗裂性指标的影响。结果表明:不同品种、不同生境鲜枣中过氧化氢酶的活性有较大变化,其中掉牙枣最高,灵宝枣最小。25 fresh jujubes that collected in Yanshui Town,Yanchuan County,Yan＇an City,Shaanxi Province were used to measure catalase activity in different varieties of fresh jujube.The research on catalase activity of jujube was to study whether it could reflect the jujube anti-cracking or not.The results showed that under different habitats the catalase activity in different varieties had great changes,the activity of CAT in ＇Diaoyazao＇ was the highest,＇Lingbaozao＇ was the lowest.
