| Abstract: | The chromosome number and karyotype of Eulophia flava were studied by applying fingertip pressing method.The results showed that the number of the chromosome of Eulophia flava was 2 n=54,the basic number of chromosome was x=27,its karyotype formula was 2 n=2 x=54=28 m+18 sm+8 st.The diploid mainly consisted of metacentric and submetacentric chromosomes.The karyotype belonged to 2B type. |
