摘　　要： 尾张温州蜜柑夏季修剪剪留长度、基粗对秋梢抽生有显著的影响；秋梢长度、基粗、新叶数与剪留长度呈线性负相关；而新梢抽生量与之呈正相关；新梢长度、新叶量与剪留基粗呈负相关；新梢抽生量正相关于剪留基粗；新梢基粗与剪留基粗间未达到显著水平相关。短截系数（Ｄ／Ｌ）认为是适宜的修剪指标；文中导出了有关回归方程，并推荐剪留梢粗为０．５～０．８ｃｍ，留梢长度７～１８ｃｍ。 The length, base diameter of the branches prunned in summer was found to have a remarkable effect on autumn shoots in Owarri satsume (Citrus unshiu Marc.). The length, base diameter of the autumn shoots and the number of leaves on it were negatively correlated to the length of the branches prunned. The number of autumn shoots was positively correlated to the length of branches prunned. There were negative correlation between the length, the number of leaves on autumn shoots and the base diameter of the branches prunned, while the number of autumn shoots was positively correlated to the base diameter of branches prunned. No significant correlation was found between the base diameter of autumn shoots and that of branches prunned. Prunning index (D/L) was taken as an applicable index for summer prunning. Regession equations concerned and a range of reference prunning treatments were given in the paper.
