| 摘 要： | 利用已进入正常开花结实期的截干矮化马尾松二代无性系种子园,以研究其开花结实的遗传变异规律.结果表明,种子园雌、雄球花量及球果数在无性系内分株间差异不显著,但在无性系间均达极显著水平,其遗传变异系数变化在37.85%～53.50%,无性系重复力皆在0.71以上.根据开花结实的调查结果,种子园无性系主要聚为雌多雄少(偏雌)...

| Abstract: | A survey was conducted to study the genetic variation of flowering and fruiting of Pinus massoniana in the dwarfed second-generation clonal seed orchard which had entered the stages of normal flowering and seed setting.Results showed that extremely significant differences were observed in strobilus and cone production among different clones,but insignificant differences among clonal ramets.The genetic variation coefficient varied from 37.85% to 53.50%,and the clonal repeatability was over 0.71.The clones co... |
