| 摘 要： | 对2.5年生的巨桉家系实生苗与巨桉无性系造林对比试验林的调查分析表明:巨桉家系的生长量总体比无性系生长慢,各无性系间或家系间生长差异极为显著。巨桉最好无性系Eg6胸径是最差无性系Eg3的121%,最好家系SB2169胸径是最差家系BS10的126%,说明巨桉单株选育效果明显,转化成的无性系必须开展造林对比试验,才能真正选育出优良无性系。

| Abstract: | Growth assessment was carried out in 2.5-year-old comparative trial stand from Eucalyptus grandis families and clones.The growth of clones was generally better than that of families and the growth variance was significant among either the clones or families of E.grandis.The diameter at breast height of the best clone Eg6 was 21% more than that of the poorest clone Eg3,while that of the best family SB2169 was 26%more than that of the poorest family BS10.It suggested the elite tree selection was efficient for... |
