| 摘 要： | 对福建漳平五一国有林场马尾松种子园雌、雄球花量观察和分析。结果表明 ,种子园雌、雄球花产量变异主要来源于年份、无性系、无性系与年份互作等效应。它们二者在无性系间、无性系与年份互作间遗传相关关系不显著 ,而在无性系内分株间、年份间相关达到极显著和显著水平。并结合实践 ,提出建园材料再选择 ,以及对现有种子园采用选择性疏伐等提高种子园球花产量 ,克服雄球花显少有效技术措施

| Abstract: | The observational and analytical results reveal that the yield variation of male and female cones in the seed orchard originates from the effects of years,clones,and the interaction between clones and years and the correlation among plant divisions or among years within their clones reaches the extremely evident or evident level.This paper,in combination with practice,also puts forward the effective technical measures of reselecting seed orchard building materials and selectively thinning the present seed orchard for raising the cone yield in the seed orchard and overcoming the few male cone phenomenon. |
