Isozyme Pattern Investigation of <I>Geodorum </I> spp.

Abstract

Isozyme patterns of 7 ecotypes of Geodorum collected from Khun Mae Kwuang National Reserved Forest  were  investigated via polyacrylamide gel electrophoresis technique using  four  enzyme  systems, i.e. acid phosphatase, esterase, peroxidase and superoxide dismutase. Cluster analysis (UPGMA) of the band patterns could allocate 4 different groups of Geodorum relevant to 4 different ecotypes. Other 3 ecotypes could not be clearly separated since similarity, at the level of 20 %, occurred in some populations of different ecotypes.
