Abstract:: The objective of this study is to determine the correlation between the stem taperingness and central shaft by free spindle pruning mode on different apple cuhivar，which selected three cuhivar，such as free spindle short shoot ‘Fuji’，free spindle long shoot ‘Fuji’，free spindle ‘Huaguan’ in Xingtang county of Hebei Province by SPSS analysis.The results showed that the stem taperingness on free spindle short shoot ‘Fuji’ was negative correlation with central shaft，but the correlation was not significant.While the stem taperingness on free spindle long shoot ‘Fuji’ was positive correlation with central shaft，but the correlation was not significant either.But the stem taperingness on free spindle ‘Huaguan’ was negative correlation with central shaft，and the correlation between the stem taperingness and the central shaft total length was significant at the 0.01 level.The results provided scientific theoretical basis for guiding the short anvil dense planting apple tree pruning technology scientifically.
