调查结果表明，油松无性系花量的变异很大。雌花在冠层外围均有分布，以中层较多，雄花主要分布在下层。花量最多的无性系是最少的倍数：雄花为２２５．８倍，雌花为８．４倍。花量与生长量指标非常密切相关。应用座标法对无性系进行评价，选出优良无性系占调查总数的２６．７％，雄雌花量分别比平均值超过５３．２％和４０．５％。这些调查结果为种子园的经营管理提供了依据。
The survey results show that the variation of flower size of Pinus tabulaeformis is very large. Female flowers are distributed in the periphery of the canopy, with more middle, male flowers are mainly distributed in the lower. Clones with the most flowers are the least fold: 225.8 times for male flowers and 8.4 times for female flowers. The amount of flowers and growth indicators are very closely related. The clones were evaluated by the coordinate method, and the elite clones were selected to account for 26.7% of the total number of surveys. The male-female flowers exceeded the average by 53.2% and 40.5% respectively. These findings provide the basis for the operation and management of Seed Garden.
