摘　　要：5年生巨尾桉无性系不同品系调查分析表明,生长最好的品系为N品系,平均树高达13 60m,平均胸径13 67cm,平均单株立木材积0 0903m3;其次为L品系,平均树高12 62m,平均胸径13 59cm,平均单株立木材积0 0839m3。抗霜性最好的为L、K、32-10品系,受害率为3 3%。不同品系间材积、树高、胸径存在显著或极显著差异。The investigations and analyses of different strains of 5yearold Eucalyptus grandis×E.urophylla clones show that the strain that grows best is N strain,the average tree height reaches 1360m,the average dbh 1367 cm,the average singletree standing volume is 00903 m3;the one grows secondly best is L strain,the average tree height is 1262m,the average dbh is 1359 cm,the average singletree standing volume is 00839m3.The strains whose frost resistance is best are L,K,and 32-10 strains,the harmed rate is 33%.There are significant or extremely significant differences between the volumes,tree heights,and dbh's of different strains.
