Abstract: In order to clarify the correlations between the free spindle pruning mode and various factors in Fuji apple, the growth data of the free spindle-shaped short branch Fuji apple Tianhong No.2 and the free spindle-shaped long branch Fuji apple Changfu No.2 in the Apple Demonstration Park of Xingtang County, Hebei Province were investigated. Using SPSS statistical software, the correlations between the stem tapering grade and various growth traits were analyzed. The results showed that in Tianhong No.2, the stem tapering grade was negatively correlated with various growth traits of the central shaft, and the correlation coefficients between the stem tapering grade and the central shaft total thickness, the central shaft average thickness, the central shaft total length and the central shaft average length were -0.228, -0.033, -0.411 and -0.430, respectively; and in Changfu No.2, the stem tapering grade was positively correlated with various growth traits of the central shaft, and the correlation coefficients between the stem tapering grade and the central shaft total thickness, the central shaft average thickness, the central shaft total length and the central shaft average length were 0.475, 0.181, 0.120 and 0.258, respectively. This paper can provide a scientific basis for guiding the construction of free spindle pruning mode in densely planted dwarf apple trees.
