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.
