| 摘 要： | 对8年生巨桉种源、家系试验林进行全面调查分析表明：生长性状在不同种源、家系间存在显著或极显著差异；形质性状在不同种源间差异不显著，在不同家系间存在极显著差异；耐寒能力在不同种源间存在极显著差异，在不同家系间差并不显著。通过综合评价和比较，选出适应福建省永安地区种植的巨按优良家系10个，树高、胸径、材积和耐寒指数平均值分别为14．80m、16．6om、0．1749m^3和4．42，树高、胸径和材积的遗传增益分别为18．96％、加．44％、67．17％；优良个体15株，其树高、胸径、材积和耐寒指数平均值分别为17．91m、20．63cm、0．2976m^3和4．85，树高、胸径和材积的遗传增益分别为44．9％、48．8％和184．1％。这些优良材料可以通过无性繁殖进行推广应用。

| Abstract: | The introduction experiment of Eucalptus grandis of 8-year-old was concucted,and the results were as follows: the difference of growth trait between provenances and families were significant or very significant.The difference in form trait were very significant between families but not significant between provenances,the difference in cold resistance were very significant between provenances but not significant between families.Through comprihensive evaluation,10 excellent families were selected,their avera... |
