| 摘要: |
| 从美国引进三代火炬松(Pinus taeda)半同胞家系种子开展育苗试验，9个月后对其苗高和地径进行了测定分析与比较。结果表明：三代火炬松半同胞家系间苗高生长差异极显著（P<0.01）；地径生长没有显著差异，生长均较好。对苗高进行Duncan分析，筛选出L2、L9和L5为苗期生长优良家系。 |

| Abstract: |
| Seedling height and basal diameter of half-sib families of Pinus taeda were studied whose seeds were imported from United States. The results showed that: There were significant differences in seeding height, while the growth of basal diameter which performed well were not significant. According to Duncan’s contrast, L2、L9 and L5 were selected for the optimal families. |
