Abstract: [Objective and Method]The major cultivation clones of one year dormant seedling of Ziziphus jujube in the oasis around Tarim Basin were used as materials to observe their one year dormant woods of relative electric conductivity and relative leakage of K~+ under different low temperature treatments,and various clones Logistic equation were established.[Result]The results show that: (1) The relative electric conductivity and relative leakage of K~+ of the clones increased with the decreased of temperature; (2) Under the same low temperature stress,the relative electric conductivity and relative leakage of K~+ were different in difference clones.[Conclusion]The comprehensive analysis was given that the difference of the cold resistance abilities of the clones were as follows:Huochengzao jujube > wild jujube> Junzao jujube> Huizao jujube.

摘要： [目的]测定环塔里木盆地绿洲的主栽品种灰枣、骏枣、砧木种酸枣及伊犁河谷抗寒品种-霍城大枣的抗寒性.[方法]以枣树一年生休眠枝条为试验材料.测定其相对电导率和K+相对渗出率,建立不同品种(或砧木)的Logistic方程.[结果](1)参试品种的相对电导率和K+相对渗出率均随着温度的降低而增加;(2)同一低温胁迫下,不同品种间相对电导率和K~+相对渗出率存在明显差异.[结论]综合分析得出不同品种间抗寒性为:霍城大枣>酸枣>骏枣>灰枣.
