The results showed that the stem taperingness on free spindle short shoot ＂Fuji＂ was in negative correlation with central shaft, but the correlation was not significant. While the stem taperingness on free spindle long shoot ＂Fuji＂ was in positive correlation with central shaft, but the correlation was not significant either. The stern taperingness on free spindle ＂Huaguan＂ was in negative correlation with central shaft, and the correlation between the stem taperingness and the central shaft total length was significant at the level of 0.01.
