通过对引进的5个滇楸家系进行了苗期对比试验,并对1 a生苗木生长差异进行分析,结果表明：5个滇楸家系间苗高生长量差异极显著;苗高、地径生长速生期均为8～10月,生长最高峰均在10月;叶长、叶柄长、叶绿素方差分析达到了极显著水平,改毛5号在5个滇楸家系中总体表现最好。本研究为滇楸家系的苗期选择及科学管理提供了依据。

By the comparison experiments conducted in five exotic families of Catalpa fargesii Bur.f.duclouxii（Dode） Gilmour in seeding stage,the analysis was made about the one-year old growth differences.The results showed that seedling height among the five families has significant difference.Both the seedling and ground diameter grew fastest from August to October.The growth peak is all in October.The differences of Variance analysis of leaf lengths,petiole lengths,chlorophyll were significant.The best one is Gaimai-5 among 5 exotic families,The authors provided basis for selection of seeding stage and scientific management of families of Catalpa fargesii Bur.f.duclouxii（Dode） Gilmour.
