| 摘 要： | 文章介绍了引进的加拿大东部白松10个种源的优良种源选择的早期研究结果.通过6年的造林试验,东部白松生长量极显著大于乡土树种红松;东部白松10个种源之间生长量存在显著差异,筛选出2个优良种源,其苗高的遗传力为86%,遗传增益为11.7%;胸径的遗传力为88%,遗传增益为63.4%.说明直接引种东部白松优良种源造林可获得显著的增产效益.

| Abstract: | Selection of superior provenances of introduced Pinus strobus from Canada was studied in this paper.Through 6-years afforestation experiments,differences were significant for 10 provenances,and growth of Pinus strobus was significantly higher than native tree species Pinus koraiensis.The heritability and genetic gains of height and DBH for 2 selected superior provenances were 0.86 and 0.88,11.7% and 63.4% respectively,which showed that afforestation with introduced superior provenances of Pinus strobus dire... |
