Abstract

We used the 7-year-old Zizyphus jujuba 'Zhanshanmizao' as a test material, and sprayed three different concentrations of GA3(50 mg/L, 100 mg/L and 200 mg/L) to it on January 30, 2017. The dynamic changes of antioxidant substances (SOD, POD, O2- and MDA) were measured after the management in order to compare the effects of different concentrations of GA3 on antioxidant substances of the jujube trees. The results showed that spraying GA3 increased the activity of SOD and POD, while decreasing the content of O2- and MDA. After different concentrations of GA3 treatment during forced dormancy (January 30 to February 14) of jujube trees, it turns out that 200 mg/L GA3 could significantly activate the antioxidant system while 50mg/L GA3 had basically no use in breaking the forced dormancy and even has the inhibition. Therefore, 200mg/L GA3 is thought to be its the most effective concentration of breaking the forced dormancy of Zizyphus jujuba 'Zhanshanmizao'.
