Abstract: POD isoenzymes of 18 varieties of winter wheat were studied by using PAGE.The result showed that the zymogram of POD isoenzymes of roots and leaves of winter wheat varied in different degree.Between returning green stage and jointing stage the zymograms of POD isoenzyme of roots varied instinctively.There increased a band RA 1 in region A and a band RC 1 in region C respectively.The two bands didn't appear in other development stages.In region C the zymogram of POD isoenzymes of leaves of jointing stage increased one band LC 1,which didn′t appear in other development stages.It was found that the band RC 4 of roots and band LC 5 of leaves were stable in four development stages,and they appeared as first grade bands.The band RA 2 of roots,in region A,was stable too,and appeared as second grade band zymogram of POD isoenzymes had no significant difference among 18 varieties of winter wheats.
