摘　　要：为筛选出生长情况较好的优良华山松家系,本研究在山西省中条山国有林管理局析城山林场对28个华山松家系开展了苗期对比试验。结果表明,华山松不同家系间苗期地径、苗高差异均达到极显著水平,其中,地径、苗高最大的分别是横河52、横河11,地径、苗高最小的是横河48。通过聚类分析,将华山松不同家系分为4类。其中,表现最好的为第4类,可将其作为未来的重点观察对象;其次为第2类和第1类,可作一般观察对象;第3类表现最差,建议将其淘汰。In order to select fine families of Pinus armandi with good growth conditions,seedling stage comparison tests for different families of Pinus armandi were carried out in Xichengshan forest farm of National Forest Administration Bureau of Zhongtiao Mountain in Shanxi Province.The results showed that the ground diameter and seedling height of Pinus armandi at seedling stage were significantly different among different families.Among them,the largest ground diameter and seedling height were found in Henghe 52 and Henghe 11,while the smallest ground diameter and seedling height were found in Henghe 48.Different families of Pinus armandi were divided into 4 categories by cluster analysis.Among them,the average growth performance of Class 4 was the best which could be regarded as the focus of observation in the future.Next were the Class 2 and Class 1 which could be used as general observation objects.The Class 3 had the worst performance which was recommended to eliminate.
