摘要
对福建南部山地67个月生36个桉树无性系的生长性状和形质性状进行方差分析,结果表明:36个无性系的树高、胸径、单株材积、冠幅、枝下高、分枝和干形在无性系间均存在着极显著差异;共有18个无性系的单株材积超过对照U6平均值0.1101 m3·株-1;综合评定法评定生长优良的3个无性系分别是No.27、No.2和No.7,生长最差的2个无性系是No.15和No.36。综合分析表明,具有尾叶桉、巨桉或赤桉遗传背景的桉树杂种无性系生长迅速、形质优良,适宜在该区域推广种植。
A growth and form-qality characters of variance analysis was conducted on 36 eucalyptus clones at 67 months old in southern Fujian.The results show that there were significant differences in growth and other characters among the different clones.There were 18 clones＇ single volume（SV） more than the CK clone＇s（U6＇s is 0.1101 m3.S-1）,and the 3 best clones were No.27,No.2 and No.7,the worst clones were No.15 and No.36,respectively.The results of synthesis analysis among characters showed that the hybrid clones of Eucalyptus spp.whose parents come from E.urophylla,E.grandis and E.camaldulensis were fit for planting in southern Fujian.
