引进史密斯桉、蓝桉等5个桉树品种152个家系在昆明市海口林场苗圃进行育苗,对苗期苗高和地径生长情况进行观测和分析.结果表明,5个桉树品种苗高和地径平均值之间存在较大变异,品种间平均苗高生长量差异达到极显著水平,品种间平均地径生长量差异不明显.经多重比较后认为,史密斯桉在海口林场苗期生长表现较好.%Five Eucalyptus varieties, 152 family including Smith Eucalyptus, Eucalyptus globulus were introduced in Haikou Forest Farm of Kunming, determination and analysis of tree height and the ground diameter also were conducted on seedling stage. The results showed that; there were big variation between five Eucalyptus varieties at average seedling height and diameter, and the differences of average height growth in five varieties was significant, but the differences of age diameter growth rate was not significant; On the base of multiple comparisons, the seedling growth status of Smith Eucalyptus performed better in Haikou Forest Farm of Kunming.
