| 摘 要： | 在4个不同地域的马尾松林分中选择79株高产脂类型的马尾松优树进行产脂力分析,结果表明:产脂量与割沟负荷率、树冠及树皮厚度相关,特别是树皮厚度对产脂量影响最大;不同产地优树的产脂力系数不同,而对照树的产脂力系数基本相近;松树的产脂力与边材中树脂道的面积大小有关,而与其数量和直径腔大小关系不大.

| Abstract: | Seventy nine plants of high-yield fat typed Pinus massoniana selected from 4 Pinus massoniana forests in different origins are analyzed in the view of fat productivity.The results show that the productivity is related to the ditch burden rate and crown,as well as bark thickness in particular.The productivity coefficients of different origins are different,while those of contrast trees are almost same.The fat productivity is related to the area of resin vessel,while it has little influence with the quantity and diameter cavity size. |

| Keywords: | Pinus massoniana excellent tree fat output fat productivity coefficient bark thickness area of resin vessel |
