摘要
通过测定40个高产脂思茅松无性系松脂产量及松节油化学组分,分析其在无性系间的变异,结果表明:各成分在无性系皆差异极显著,且无性系遗传力为0.53~0.96,说明这些化学组分受较强遗传因素控制,选择育种潜力大,选择特定松节油化学组分无性系可取得较好的效果;产脂量与α-蒎烯呈显著的正相关关系。
To study the genetic variation of resin yield and chemical components,the resin yield and chemical components were measured and the variation and correlation among the components of 40 clones were analyzed. The analysis of variances indicated extremely significant difference in all components acid among the clones,and the heritability was 0. 53 - 0. 96,which indicated that these chemical components were controlled by strong genetic factors with strong breeding potential. The clone selection with specialty chemical composition could achieve better results through clonal selection. There was a significant positive correlation between resin yield and alpha pinene.
