摘　　要：对35个思茅松高产脂嫁接无性系的树脂道个数进行测定,并对其与产脂力的关系进行回归分析。结果表明:树脂道个数与产脂力的相关关系较为紧密,经过对18个回归方程的拟合,得出树脂道个数与产脂力的最佳回归方程为:y=a+becx。Based on the data of resin duct quantity of 35 grafting clones, an analysis on the relationship between the resin duct quantity and the resin productivity was proceeded, the result showed that the resin dust quantity had a close relationship with resin productivity, through the fitting with 18 regression equations, the optimal regression equation between resin duct quantity and resin productivity was： y = a ＋ be^cx.
