摘要
本文采用直接羽髓法对３只蓑羽鹤幼体进行了染色体组型分析，确定蓑羽鹤染色体数为２ｎ＝８０，其中包括１８条大染色体（相对长度在４％以上），６２条微小染色体．
With the method of direct-feather-marrow determination,the karyotype of three young demoisellecranes was analysed.It was decided that the chromosome number of demoiselle crane is 2n=80, inwhich 18 chromosomes are bigger in size (relative length over 4%)and 62 ones smaller.
