| 摘 要： | 通过对23个杂种桉无性系的生长性状、形质性状和材质性状进行了差异分析和比较,结果表明:除圆满度和分枝外各性状在无性系间均差异极显著,经多重比较共有13个无性系的去皮蓄积量超过总体平均值,生长量最大的是DH32-28,其去皮蓄积量是最小无性系W5的778.91%,是总体平均值的143.55%,是对照的234.85%;无性系各性状重复力为0.15~0.85,树高和胸径的重复力最大,圆满度的重复力最小;早晚秩次相关分析表明:可对参试无性系进行早期选择;应用指数选择法,从23个参试无性系中筛选出了6个优良无性系,分别是DH32-28、DH33-27、GL9、DH32-13、DH33-9和DH32-29。

| Abstract: | A variance and analysis was conducted on growth characters and other characteristics of 23 eucalyptus clones.The results showed that there were significant differences on growth and other characteristics among the different clones except stem plump degree and branch size.After multiple comparison,there were 13 clones forest standing stock more than the mean of whole population(all clones),meanwhile,the forest standing stock of best clone DH32-28 was 7.7891,1.4355 and 2.3485 times of the worst clone W5,the ... |
