摘要: 为比较不同品种枣树的耐寒性,以冬季1—2月份天津市大港初代冬枣、二代冬枣、马牙枣、马奶枣等品种的一年生枝条为试材,分别测定了不同品种的可溶性糖、可溶性蛋白质、水分、丙二醛含量的变化。结果表明:马奶枣一年生枝条的可溶性糖含量和含水量最高,马牙枣的可溶性蛋白质含量最高,二代冬枣的丙二醛含量最高,初代冬枣均较低。综合分析显示:耐寒性依次是:马奶枣>马牙枣>初代冬枣>二代冬枣。

Abstract: In order to compare the cold tolerance of different jujube varieties, the soluble sugar, soluble protein, water malondialdehyde in the annual branches of different varieties were determined with the first generation and the second generation of Dong Zao, Ma Ya, Ma Nai in Tianjin Dagang. The results showed that the soluble sugar and water of the annual shoots in Ma Nai jujube were the highest, and the soluble protein of Ma Ya was the highest. The malondialdehyde of the second generation of Dong Zao were the highest, followed by the first generation. The comprehensive analysis showed that the cold resistance was in the following order: Ma Nai>Ma Ya>Yi Dai Dong Zhao>Er Dai Dong Zhao.

Key words: jujube, variety, cold tolerance, physiology, dormancy
