| 摘 要： | １９８８－１９９０年在河南卢氏油松种子园３ａ的观测表明，３１个无性系的花期早晚和长短有较大差异，但不存在花期不遇的问题；不同年份无性系间和无性系内雌雄球花量变异明显。据此，对３１个无性系作系统聚类，分别按花期物候和雌雄球花量划分为５类和３类，为重建种子园无性系再选择作了初步工作。

| Abstract: | Three years' (1988~1990) observation showed that blooming date and duration had a marked difference among 31 clones of Pinus tabulaeformis in the seed orchard located in Lushi County, but blooming date of different clones overlapped completely. Male and pistillate flower production had a notable difference among the clones and the divisions of same clone in different years. These were related to some characteristics of clones, the cumulative temperature before flowering, the temperature and moisture conditions during flowering, the tree nutritional level and the location of flowers in the crown. On these grounds, cluster analysis was made among 31 clones for the sake of the clonal selection of rebuilding seed orchard. |
