Abstract: Isoenzyme patterns of peroxidase, catalase, glucose-6-phosephate, glutamate and isocitrate dehydrogenases, esterase, amylase and IAA oxidase in the embryos, endosperms, roots and shoots of wheat seedlings (Triticum aestivum L. var. Nung-da 139) were determined by horizontal starch gel electrophoresis and polyacrylamide gel disc electrophoresis respectively. The number of isoenzymes of peroxidasc and amylase was increased with the concomitant increase of days during germination. The isoenzyme bands of esterase, glutamate, glucose-6-phosphate and isocitrate dehydrogenases in the embryos were more in the begining of germination. The activities of pero- xidase, IAA oxidase and glutamate dehydrogenase in roots were higher than those in shoots. On the contrary, the activities of catalase and glucose-6-phosphate dehydrogenase in shoots were higher than those in roots. However the activity of esterasc was slight higher in shoots. There was no difference in the activity of isocitrate dehydrogenase between roots and shoots. The morphological difference of shoot and root is evidently related to isoenzyme patterns. This investigation indicates that different metabolic characters are existed in shoot and root during differentiation.
