Abstract: Based on gel electrophoresis method,the gene diversity of Fagus lucida,F.pashanica and F.engleriana was studied in this paper.The allozymes determined include peroxydase(PX1 and PX), phosphogluconate dehydrogenase(PGD), superoxyde dismutase(SOD), glutamate oxaloacetate transaminase(GOT1 and GOT2),isocitrate dehydrogenase(IDH),menadione reductase(MNR),phosphoglucomutase(PGM and PGM2), and malate dehydrogenase (MDH2). We have determined and analysed the allelic frequency and the genetic distances of the three beeches, and provided some scientific information for the further studies of taxonomic relations and systematic evolution of the beeches.
