| 摘 要： | 对油松开花同步性、配子贡献和16个主要数量性状遗传水平的研究表明,无性系间的平均开花同步指数间有较大差异,开花同步指数的总平均值为0.569;配子贡献不同无性系差异较大,少数无性系对于配子库没有贡献;主分量分析的结果把16个性状浓缩成第1主成分雄花因子,第2主成分1年生球果数量因子,第3主成分球果形状因子;通径分析显示雄花和雌花的数量对于球果产量决定系数分别为0.43和0.363,均达到极显著水平.

| Abstract: | Studies were conducted on the genetic variation of Pinus taburaeformis flowering synchronization,gametic contribution and 16 quantitative traits.The results indicated that there was significant difference between clonal flower synchronization indexes,with a total average value of flower synchronization inesx of 0.569;The difference of gamete contribution was large greatly in clones and a little clones had no gamete contribution to the whole gamete pool.From main component analyses we got three main factors: the male flower factor,the factor of cone number and the factor of cone shape;the pass way analyses show the determinant index from 16 quantitative traits of Aoc are necessarily bound up with the number of male and female flowers(dAMF-AOC=0.43,dAFF-AOC=0.363). |
