摘要
本文报道了我片蒲公英(TaraxacumasiaticumDahlst)的核型公式为K(2n)=4x=32m(4SAT),核型为"1B'型,核型不对称系数为54.83%,染色体相对长度组成为2n=32=8L+M2+8M1+8S,染色体总长度为21.83μm。
The present paper deals with cytologial study on Taraxacztm asiaticumDahlst. The number of chromosomes in root-tips of seedings has been found to be 2n=32,the karyotype formula of T. asiaticum is K(2n)=4x=32m (4SAT) and be long to 'IB' ofstebbins karyotype symmetry. The species chromosome composition of relatine length is 2n=32=8L+8M2+8M1+8S, The totoal length of the chromosome is 21. 83um.
