摘　　要：　赤桉E.camaldulensis是桉树种类中较为耐低温的一种.为了引种适合湖南永州气候条件、抗低温、且速生丰产的赤桉无性系,对赤桉7个优良无性系进行了对比试验.经4年冬季的严寒低温、霜、雪、冰冻的考验,对其树高、胸径、材积等因子采用双因子方差分析,对无性系的差异进行Q检验,结果表明,赤桉无性系34号综合性能最佳,可在永州市南部6县发展.并对赤桉无性系34号扦插繁殖方法进行了研究. E.camaldulensis is one of the many varieties of Eucalyptus, which is characteristic of coldresistance. In order to make it resist low temperature, grow quickly and yield highly when planted in Yongzhou, we have done a contrast experiment on its 8 preponderant clones. After the test of 4 winters' low temperature, frost, snow and freeze, and by measuring the tree height and chest height diameter, calculating the volume, using the analysis of variance of double factors and making Q tests on the differences of the clones, we have found that E.camaldulensis 34 grows quickly, not easy to be hurt by frost and snow, and having the best experiment results. Breeding E.camaldulensis 34 by its cuttings has led to the cultivation of 8×106 seedlings and a quickgrowing, highyielding forest of 2.667×103　hm2.
