| 摘 要： | 在吉林省汪清林业局天然红皮云杉母树林中选择优树并采种,对苗期生长性状进行测定,同时做家系间和家系内选择,结果表明:45株优树的子代苗期生长性状差异显著,4 a生苗高、地径大于对照的有34个和29个家系,平均增益为5.60%、4.55%;按照大于对照5%的标准共选择出22个优良家系,入选家系平均苗高和地径增益为11.17%、10.45%;家系内选择后平均苗高、地径增益为15.45%、15.38%。 |

| Abstract: | Fine strains of Picea koraiensis were selected and seeds were collected in natural forest of Wangqing Forest Bureau in Jilin province.The growth of seedlings was measured for inter-and intra-strain selection.Results showed: the seedlings from 45 strains had significant growth.There were 34 strains grew higher,29 strains had bigger base diameter than the controls,which increased 5.60% and 4.55%,respectively.According to the standard that higher than the 5 % of control,22 strains were selected with 11.17% height and 10.45% diameter increased on average.The average increase on height and diameter were 15.45% and 15.38% after selection within strains. |
