摘　　要：对赤桉8号、赤桉2号的适应性试验结果表明,赤桉8号和赤桉2号的适应性和速生性较强,造林当年树高可达3.0 m,近2年生树高、胸径分别可达5.6 m和5.3 cm以上,达到福建省一般产区桉树速丰林标准;赤桉8号的抗风性较强且可耐-3.0℃左右的低温,赤桉2号抗风性极强且可耐-5.0℃左右的低温。作为耐寒抗风无性系,这2个无性系在闽东沿海较高海拔山地有一定适应能力,可进一步试种,尤其是赤桉2号,极具发展潜力。Adaptability test on Eucalyptus camaldulensis 8 and 2 at coastal mountainous region of eastern Fujian resulted that these two clones had strong adaptability and grew fast, tree height growth reached about 3.0m in the current year, tree height and DBH of the first two years reached 5.6 m and 5.3 cm, similar to the standard of fast growing and high yield E. camaldulensis in Fujian province. E.camaldulensis 8 had advantages of strong resistance to wind and cold hardiness to - 3℃, and E.camaldulensis 2 had even stronger resistance to wind and cold hardiness to - 5℃. Therefore, these two clones could be planted in the eastern Fujian, especially E.camaldulensis 2 had prospect potential
