| 摘要: |
| 桉属7个种11个种批进行生长和耐冻性的联合选择研究。选出在冷凉地区较有潜力的邓恩桉17913、20665和17922以及本沁桉18788共4个种批，蓄积量14.80～20.93 m3/a?hm2，这为国内冷凉地区发展短轮伐期桉树用材林提供了可供选择的速生、耐冻的种植材料。另外，多雷苷桉虽然生长中等(蓄积量10.03 m3/a?hm2)，但耐冻性好，可以作为进一步选择和杂交育种的备用材料。 |

| Abstract: |
| Selections were carried out on growth and cold tolerance in 11 Eucalyptus seedlots representing seven species. Three E. dunnii seedlots (17913, 20665 and 17922) and one E. benthamii seedlot (18788) were selected out, being 14.80～20.93 m3/a?hm2 in MAI, which had great potential to be used in the plantation practices in cold and cool regions of China. In addition, E. dorrigoensis performed well in cold tolerance though medially in MAI, which could serve as a sound candidate for further selection and hybridization. |
