通过对草河口１９７７年营建的红松种子园８年的观察研究发现，各无性系雌球花开花株率呈增加趋势，系间差异显著；雄球花多集中在树冠中、下部，少数无性系花粉在园中起垄断作用；种子园中只开雄球花的树木比例大，占５３．８５％，只开雌球花的树木比例很小，占１．０３％，开两性花的占２７．６９％。系间结实量差异极显著，年度间相关紧密，但与树体生长性状相关不显著。 Based on the observation of the korean pine orchard that was built in Caohe Estuary in 1977 for 8 years, it is found that the flowering rate of female flowers in all clones has an increasing trend with significant differences among the lines. The male flowers are mostly concentrated in the middle and lower parts of the canopy, Department of pollen play a monopolistic role in the park; the seed orchard only open the ball of male flowers accounted for a large proportion of trees, accounting for 53.85%, only a small proportion of female flowers of the tree, accounting for 1.03% 27.69%. Significant differences between the tillage between the lines, closely related to the year, but not significantly correlated with the growth traits of trees.
