Abstract

Seven-year-old tree of Ziziphus jujuba ‘Zhanshanmizao’ cultivated in field were used to study the degree dormancy, chilling requirement (CR) and dormant physiological indexes such as the content of water, carbohydrates, free amino acid, and soluble protein. The results showed that the Z. jujuba ‘Zhanshanmizao’ bud had a dormancy from early November, finished the natural dormancy from early January, then came into an enforce dormancy. Among ≤ 7.2℃ model, 0-7.2℃ model, and Utah model, 0-7.2℃ model is suitable to be used for measuring the CR of Z. jujuba ‘Zhanshanmizao’ in Santai area, and the CR of Z. jujuba ‘Zhanshanmizao’ was 494 h. The content of free water, soluble protein, and starch were after rising to decline, but bound water/free water ratio, the content of soluble sugar, and free amino acid were after the first drop and then up in the period of the natural dormancy.
