摘　　要：在闽北南部延平区太平试验林场开展7个桉树无性系的引种试验,结果表明:巨桉3号适应性、速生性和耐寒性强,生长潜力大,产量高,可耐-4℃^-4.5℃的低温,适合在福建中亚热带暖温区海拔400 m以下的山地栽培;巨桉1号、DH184-1和DH201-2适应性、速生性和耐寒性较强,有一定生长潜力,产量较高,可耐-3℃^-4℃的低温,适合在福建中亚热带暖温区海拔300 m以下的山地栽培;赤桉3号和赤桉1号速生性、生长潜力和产量均一般,但其耐寒性强,可耐-5℃的低温,适合在该区海拔500 m左右的山地栽培;柳窿桉9号的速生性较强、有一定生长潜力,但其耐寒性弱,只可耐-2.0℃^-2.5℃的低温,不宜在该区发展.The clone introduced experiment of seven Eucalyptus spp. were conducted in Taiping Experimental Forestry Farm in the south of Northern Fujian. The results indicated that Eucalyptus grandis No. 3 were strong in adaptability, fasting growth, and cold-resistance, and high in growth potential and yield with the endurance of low temperature at -4℃ - -4.5℃ and suitable for cultivating in the mountains below 400 m of the elevation. Eucalyptus grandis NO. 1, DH184-1 and DH201-2 were strong in adaptability, fast-growth and cold resistance, had certain growth potential and relatively high yield, with the endurance of low temperature at -3℃- -4℃ , suitable for cultivating in the mountain below 300 m of the elevation, middle-subtropical temperate zone of Fujian. Eucalyptus camaldulensis No. 1 and No. 3 were normal in fast-growth, yield and growth potential, but strong in cold resistance at -5℃ , suitable for culti-vating in the mountain at around 500 m above sea level. Eucalyptus saligna × Eucalyptus exserta No. 9 were strong in fast-growth, certain growth potential, but poor in cold-resistance at -2.0℃ - -2.5 ℃, un-suitable for developing in this area.
