ORDINATION ANALYSES OF 19 SPECIES OF BRYOPHYTA BASED ON SOD AND EST ISOZYMES

Abstract

Abstract: By polyacyacrylamide get electrphoresis, two isozymes:Esterase(EST)and Superode dismutase(SOD)of 15 species of Musci and 4 species of Hepaticae were studied. Zymogramatic differences of two isozymes in 19 species were numerically revealed by Principal Component Analysis (PCA). The results showed as follow:1)Bryophytes are of high genetic diversity;2)Based on isozyme data, PCA could be applied to reveal the systematic relationships among different bryophyte species in genetic level.

Key words: Bryophytes, Esterase(EST), Superode dismutase(SOD), Isozyme, Principal Component Analysis(PCA)
