Abstract

7-year-old trees of Ziziphus jujuba ‘Zhanshanmizao’ were used to study physiological indexes. Using SA spray the trees with different concentrations in January 30 th, 2017. Study the changes of water, Organic nutrients (starch, soluble sugar, soluble protein, and free amino acid) and antioxidant system (SOD, POD, O2-, and MDA). Then, measure the fruit quality, The effects of salicylic acid (SA) with different concentrations On breaking forced dormancy of Z. jujuba ‘Zhanshanmizao’ trees were compared. The results showed that in the forced rest period (form 30 th January till 14 th February) the effect on gibberellin at 200 mg/L, potassium nitrate at 6 % and SA at 6 mmol/L breaking forced dormancy were better than others, they can improve the ratio of the free water and the bound water significantly. Change the content of organic nutrient composition rapidly, Active the antioxidant system. SA (2 mmol/L) had little effect on dormancy-release.
