%X A gel electrophoresis method,was used to study the genetic diversity of Fagus engleriana and F.pashanica at Nanjiang Country,Sichuan Province.Ten allozymes were identified and they are:Peroxydase(PX 1 and PX 2),Phosphogluconate dehydrogennase(PGD),Acide phosphatase(ACP),Superoxyde dismutase(SOD),Glutamate oxaloacetate transaminase(GOT 1 and GOT 2),Isocitrate dehydrogenase(IDH),Phosphate glucose isomerase(PGI),Menadione reductase(MNR),Phosphoglucomutase(PGM 1 and PGM 2),and Malate dehydrogenase(MDH 2).We have determined and analysed the allelic frequency,genetic diversity,fixation index,Hardy Weinberg equilibrium,and genetic distances of the 2 beech species.This results could be applied in the silvicultural practice,such as genetic improvmemt and species selection,and they could also provide some basic scientific information for the further studies of taxonomic relations and systematic evolution of the beech species in China.
