Abstract

In this experiment, the 7-year-old Ziziphus jujuba ‘Zhanshanmizao’ tree with the same tree potential was used as the test material, and different time (December 5 th, 2016 and January 16 th, 2017) was selected to be treated with their sheds and exposed to uncovered open fields for comparison. The contents of antioxidative substances malonyldialdehyde (MDA), superoxide dismutase (SOD), peroxidase (POD), and O2-• in the shoots of jujube trees were measured at each treatment level, the mechanism of the dormancy release of Z. jujuba ‘Zhanshanmizao’ was explored. The results showed that (1) the two treaments of jujube trees were relieved in January 17 th and around January 17 th. The contrast were relieved around February 14 th, and the two treatments of jujube trees relieved the dormancy about 30 d in advance. Comparing the effect of the two treatments, shed 2 was better than shed 1. (2) in the process of dormancy release, the treatments with shed significantly increased the activities of POD and SOD. (3) the contents of MDA and O2-• in Z. jujuba ‘Zhanshanmizao’ shoots with shed were less than contrast.
