摘要: 对林口县青山林场黄波罗2年生高生长变异进行了分析。不同种源内存在丰富的变异,变异幅度在20.1%~31.2%之间;种源间苗高差异极显著,其中,兴隆、方正以及迎春种源高生长较快,青山、苇河居中,嘉荫种源高生长最差,生长最快的兴隆种源较生长最慢的嘉荫种源高生长快56.5%。而兴隆种源家系内也存在丰富的遗传变异,变异系数在14.4%~23.4%之间,平均为18.6%,家系间苗高差异极显著。生长较慢的嘉荫种源家系内存也在丰富的遗传变异,变异系数在12.7%~31.0%之间,平均为21.9%,家系间苗高差异极显著, 3个生长快的家系超过生长慢家系数值的56.6%,生长最快的嘉6较生长最慢的嘉11家系高生长快75.4%。

Abstract: The height growth variation of Phellodendron amurense was analyzed. The studied materials are two years old seedlings in Qing Mountain forestry center of Linkou county. The study shows that there are rich variations within the different germplasm resources. The variation parameter fluctuates among germplasm resources is from 20.10%~31.2%. The height growth of the different germplasm resources reaches the extreme marked level, the height in the germplasm resources of Xinglong, Fangzheng and Yingchun are the fastest, medium in Qingshan and Weihe, and the lowest in Jiayin germplasm resources. The height growth of the Xinglong germplasm resources is faster 56.5% than that of Jiayin. There are rich variations within the Xinglong germplasm resources, the variation coefficient is 14.4%~23.4%, the average value is 18.6%. The differences between seedling height of families reach the extreme marked level. There are rich variations within the Jiayin germplasm resources and families. the variation coefficient is 12.7%~31.0%, the average value is 21.9%. The differences between seedling height growth of families reach reach the extreme marked level. The three families is faster 56.6% than the lower families in the height growth. Jia-6 is faster 75.4% than Jia-11.
