With annual dormant branches of Lingwu long jujube and Zhougning round jujube as the test material and conductivity was determined after the low temperature treatment. With the calculation of Logistic equation the results show that the cold resistance temperature and semi-lethal temperature are -33.58℃ and -34.44 ℃ respectively. The cold resistance of Zhongning round jujube is better than that of Lingwu long jujube.
