NUMERICAL CHEMOTAXONOMIC STUDY ON RHODOTORULA RUBRA
深红酵母的化学数值分类学研究

Research of Numerical Chemotaxony was carried out by using thePyGC data on 29 strains of Rhodotorula rubra. Numerical taxonomic techniques consist of Q -type Hierachical Cluster, Principal Component Analysis & Q -factor Analy-sis. The results showed that no matter what kind of numerical taxonomic techniqueswere used, the same taxonomic result can be obtained' Among them, Q-factor Analy-sis gave the best result. In this study, 29 strains of Rh. rubra were clustered into 4taxonomically different groups. Considering the obvious taxonomic specificity of strainNKR111, the author suggests that it should be seperated out from Rh. rubra and re-tained its original name as Rh. pilimanae.
