黑松 ·赤松无性系生长及生理生化的差异性分析

Differences of Growth,Physiology and Biochemistry of Pinus thunbergii and Pinus densiflora Clones

对12个黑松无性系和8个赤松无性系进行生长及生理生化差异性分析。通过测定地径、树高、冠幅、可溶性糖含量、叶绿素含量、硝酸还原酶(NR)活性、多酚氧化酶(PPO)活性、过氧化物酶(POD)活性等指标对不同无性系进行综合评价。综合聚类分析结果,筛选出黑松1#、11#、14#和赤松23#、28#5个无性系生长性状良好,具有较强的代表性,是重要的种质资源,应加以保护和利用。

The growth,physiology and biochemistry characteristics of 12 Pinus thunbergii and 8 P.densiflora clones were analyzed by the indications of ground diameter,tree height,tree crown width,soluble sugar content,chlorophyll content,nitrate reductase(NR)activity,polyphenoloxidase(PPO)activity and peroxidase(POD)activity.Based on the clone characteristics and dendrogram analysis,a total of 5 clones with well growth characteristics,including 3 P.thunbergii(1#,11#and 14#)and 2 P.densiflora(23#and 28#)resources,were selected for selection of superior clones,which should be protected and utilized in the future.
