| 摘 要： | 对林口县青山林场落叶松杂种苗与各优良种源苗(2年生)进行变异分析的结果表明,各种源间存在丰富变异,变异系数在26.8%～46.9%之间,平均为32.8%;各种源间苗高生长量差异极显著,青山种源杂种苗高生长最快,为49.21cm,小北湖优良种源苗高生长最慢,为22.6cm,青山种源高生长比小北湖种源高生长快117.7%;23个落叶松各家系间苗高差异极显著,生长最快的黑龙江青山Q6号家系(58.04cm)比生长最慢的小北湖家系(22.6cm)快156.8%.各家系内苗高存在丰富变异,变异系数在17.5%～46.9%之间,平均为26.3%.种源内家系间苗高差异极显著.

| Abstract: | The growth variation of hybrid larch and superior provenance seedlings(2 years old) in Qingshan Forest Farm Linkou County were analyzed.The results showed that there was a rich variation among the provenances.The coefficient of variation was from 26.8% to 46.9%,and the average was 32.8%.The difference of height growth among provenances was significant.The height growth of Qingshan was the 49.21cm,being maximal.The Xiaobeihu was 22.6cm,being minimum.The former increased by 117.7% than that of the latter.The height variation was significantly different among the 23 hybrid larch families.The fastest height growth of Qingshan Q6 family(58.04cm) exceed by 156.8% than the slowest height growth of Xiaobeihu family(22.6cm).There was a rich variation of height in families.The coefficient of variation was from 17.5% to 46.9% and the average was 26.3%.The difference among families in the same provenance was very significant. |
