Analysis of Karyotypes and Resemblance-near Coefficients of Agastache rugosa From Different Areas
摘要
Abstract
In order to explore the karyotype characteristics and evolutionary relationships of Agastache rugosa from five different areas,A.rugosa,come from Shangqiu,Henan (HNSQ),Chengdu,Sichuan (SCCD),Handan,Hebei (HBHD),Anguo,Hebei (HBAG),and Changchun,Jilin (JLCC),were used as experimental materials.The karyotypes of A.rugosa from five different areas were analyzed using conventional pressed slice method and clustered with resemblance-near coefficient.The results showed that the chromosome numbers of A.rugosa from five different areas were 18.Chromosome types of A.rugosa consisted of sm,m,st and M,asymmetry coefficient was ranged from 59.48％ to 65.43％.The karyotype of A.rugosa from HBHD was 3B,the others were 2B.Karyotype clustering analysis showed that the genetic relationship between JLCC and HBAG was closest,with the highest resemblance-near coefficient of 0.9982,and their evolution distance was 0.0018.The farthest genetic relationship was between SCCD and JLCC,and their resemblance-near coefficient was the lowest,0.9716,and their evolution distance was 0.0284.The karyotype varies within A.rugosa from different areas.Among five areas,the karyotype of A.rugosa from JLCC was the most primitive,and SCCD area was more evolutive.The karyotype differences and evolutionary relationship among A.rugosa from different areas were defined in this study,which lays the foundation for further study of cell classification issues of A.rugosa.关键词
