- Abstract
The 7-year-old Ziziphus jujuba ‘Zhanshanmizao’ as experimental material was used to measure the water content and organic nutrients (starch, soluble sugar, soluble protein, and free amino acid) in jujube branches and analyze the fruit quality after spraying jujube trees with different concentrations of gibberellin (GA3) on January 30th, 2017. The effects of different concentrations GA3 on breaking forced dormancy of jujube trees were compared. The results showed that in the forced dormancy period 200 mg/L GA3 can significantly increase the ratio of free water to bound water in jujube buds, rapidly affect the composition changes of organic nutrients and activate antioxidant system. This concentration of GA3 breaking the forced dormancy of jujube buds is better than other concentration treatments. 50 mg/L GA3 is basically ineffective and even inhibits the breaking of forced dormancy. Combined with the analysis of fruit quality at later stage, the experiment is found that 200 mg/L GA3 is the most effective concentration to break forced dormancy of jujube.
