Abstract:
With ‘Xilin No.3’ walnut as experimental material,which was planted in Walnut and Chestnut Experiment Station of Northwest Agriculture and Forestry University.Through phonological observation and growth dynamic determination of fruits,the growth dynamic measurements were fitted by Logistic Model,and each growth period of fruits was calculated.The results showed that the relationships between the increments and the growth times of the longitudinal diameter,transverse diameter and side diameter of ‘Xilin No.3’ walnut fruit were highly consistent with the Logistic Model,the coefficient of determination R2 were 99.38%,99.42% and 99.05% of the dependent variable,and the statistical test of regression equation reaches significant level；the growth process of fruit longitudinal diameter,transverse diameter and side diameter could be divided into three periods：initial-growth period,fast-growth period and stable-growth period,which provided a reference for determining the different periods of walnut cultivation and management measures.
