Abstract: In order to research the effects of two kinds of antifreeze, the electrolyte leakage rate changes of ‘Tailihong’jujube branches were studied under treatments at -16℃, -21℃ and -26℃ for 12 h with different concentration of antifreeze. The results showed that the electrolyte leakage rate of the branches at -21℃ and -26℃ was lower than 50% with antifreeze made by Zhengzhou Biaodian Chemical Co.,Ltd, while the rate of control was bigger than 50%. The research results proved that this antifreeze product of Zhengzhou Biaodian Chemical Co.,Ltd possessed some antifreezing effects and could make the tolerant critical temperature 4℃ to 5℃ lower than control for‘Tailihong’jujube branches. However, there were no significant differences between self-made antifreeze and control which revealed self-made antifreeze with no antifreezing effect on‘Tailihong’ jujube branches under these experiment conditions.
