摘要
对林口县青山林场兴凯湖松1年生高生长进行变异分析的结果表明,兴凯湖松种源间存在丰富的变异,变异系数范围在225%～249%之间,平均值为235%;3个种源间苗高生长量差异极显著,鸡东、密山种源高生长较快,鸡西种源高生长最差,鸡东种源生长量较鸡西种源快104%。49个家系苗高差异极显著,生长最快的密山3号家系同生长最慢的鸡西18号家系相比快620%。种源内家系间苗高存在丰富的变异,变异系数在137%～343%之间,平均值为203%;种源内家系间苗高差异极显著。
The height growth variation of Pinus takahasii was analyzed The studied materials are one-year-old seedlings in Qingshan Forestry Center of Linkou County The study shows that there are rich variations among Pinus takahasii germplasm resources,which the variations parameter fluctuates from 22 5%to 24 9%and the average level is 23 5% The differences of seedling height growth among three germplasm resources reach the extreme marked level The height growth of Jidong and Mishan germplasm resources is the fastest and that of the Jixi germplasm resource is the slowest Jidong family is faster than Jixi is 10 4% There are extreme marked variations on seedling height among 49 families The difference between the height growth of Mishan 3 germplasm resources is the fastest and that of the Jixi 18 germplasm resources is the slowest is 62 0% There are abundant of variations between the families in germplasm resources and the variation parameter is from 13 7%to 48 2%and the average level is 20 3%;Seedling height growth between the families in germplasm resources reach the extreme marked level.
