| 摘 要： | 采集抗寒巨桉单株的萌芽条,通过组培方式繁殖试验苗,以邓恩桉、赤桉、巨桉无性系Eg5、广林九、巨赤桉无性系DH201-2、尾巨桉无性系DH3229等品系作对照,经过多点对比试验的生长观测、抗寒性调查、抗雪压调查以及主要病虫害抗性的测定与调查,综合评价了井冈1号的生长与适应性,并讨论了井冈1号的适宜栽培区域和发展前景。结果表明:井冈1号的抗寒性与邓恩桉、赤桉接近,但抗雪压能力较邓恩桉、DH3229好,井冈1号的保存率、高生长和胸径生长均比邓恩桉、赤桉、Eg5等抗寒品系好。 |

| Abstract: | Jinggang No.1 was selected from an Eucalyptus grandis plantation after severe frost bite and was propagated by tissue culture. It was tested at several sites with E. dunii, E. camalduensis, E. grandis clone Eg5, E. grandis × E. urophyla clone Guanglin 9, E. grandis × E. camalduensis clone DH201-2 and E. grandis × E. urophyla clone DH3229 as controls. Based on growth measurement, cold-resistance evaluation, snow pressure resistance investigation and tests of common pests and diseases, its growth, adaption capacity and cultivation prosperity were evaluated. The results showed that its cold resistance was close to that of E. dunii and E. camalduensis, the snow pressure resistance was stronger than that of E. dunii and DH3229, the preserving rate, height growth and diameter growth were higher than those of E. dunii, E. camalduensis and Eg5. |
| Keywords: | cold resistance Eucalyptus grandis clone Jinggang No.1 |
