| 摘 要： | 对樟子松在五台，宁东，太白三个地点的苗期和幼林期的生长性状进行了分析。结果表明：不同种源间高生长存在极显著的差异，种源内个体变异也十分明显。高生长是随纬度增高而递减的渐变模式，而发芽率和发芽速度则无明显的地理变异。初步选择出生长良好，稳定性强的１３、１６、２０、１５、２号种源。

| Abstract: | Analyzing the growing characteristics in the seedings and juvenile stage in Wutai,Ningdong and Taibai regions showed that there are significant differences in the hight among the seed sources,obvious variation is found in the same provenance,the hight is gradually change type on the major direction of latitude germination rate,and seeding speed is no obvious geographic variation. The growing well and steady of the provenance 13, 16, 20, 15 and 2 is preliminary selected. |
