对福建五一林场马尾松种子园嫁接植株分枝与结实特性及二者相互关系的分析表明：（１）每年侧枝数在无性系间未发现显著差异，但年度间差异显著；同一年份侧枝粗、侧枝断面积和两个性状在无性系间具显著差异，不同年度间差异极显著；（２）无性系球果以单果簇、二果簇、三果簇为主，可集中分布在树冠的上部、中部、下部或较均匀分布；（３）某一轮侧枝的球果产量与该轮侧枝总数无显著相关，但与该轮侧枝断面积和密切相关；单一侧枝的球果产量与基枝径密切相关。
The results showed that: (1) There was no significant difference in annual number of branches between clones in the clones of Pinus massoniana seedlings in Wuyi Forest Farm, Fujian Province, but the difference was significant in the year; in the same year, , The cross-sectional area of the branches and the two traits were significantly different among the clones, and the difference was significant in different years. (2) The single-fruit, two-fruit and three fruit- (3) There was no significant correlation between the yield and the total number of lateral branches in one round of lateral branch, but it was closely related to the area of the lateral branches Path is closely related.
