| Abstract: |
| This paper briefly presents the principles and methods of cluster analysis of the genus Rhizobiura.It discusses some problems in choosing and classifying strains and their characters,and describes the methods and main steps to collect raw data,code characters for programs, calculate similarities between strains,and classify and choose the characters of identification with the use of a high-speed computer. In the end,Dv(rigour)and Dp(pattern)analyses of the strains are used to explain the differences between... |
