[Methods]A total of 2 tree structures were selected,namely,the slender spindleshaped Zhongqiuwang from Shen County of Hebei Province and slender spindle-shaped short shoot Fuji from Xingtang County of Hebei Province,to investigate the growth indicators of the small central shafts. SPSS analysis was used to compare the correlations between the taperingness with the growth factors of the small central shafts. [Results]The stem taperingness on slender spindle-shaped Zhongqiuwang was positively correlated with the various growth factors of the small central shaft,and the difference in the positive correlation with average roughness reached the extremely significant level. The stem taperingness of slender spindle-shaped short shoot Fuji was negatively correlated with the total roughness of small central shaft,but was positively correlated with the average roughness,total length and average length. [Conclusions] The results provided scientific and theoretical basis for guiding the dense planting of dwarfing apple tree pruning technology.展开更多
The progress in protoplast technology and its application in fruit breeding were summarized,and the existing problems and application prospect were also discussed.
