Abstract: Peroxidase （POD）and esterase （EST） isoenzymes were analysed in sporophyll, stem and leaf in three populations （ native, Japanese and half - bred ） of sea mustard Undaria pinnatifida by electrophoresis. The results showed that the POD activity was higher in the sporophyll than that in the stems and leaves in which the POD activities were weak from bottom to top in native plant. For the Japanese plant, the POD activities of the stems and leaves were the same in all positions. However, the activity was slightly higher in midportion of a leaf than that in stems. The high enzyme activities were observed in mid - bottom stems in the haftbred plant, and the activity was higher in bottom leaf than that in mid -top leaf. The EST enzyme activity was higher in the sporophyll than that in the stems and leaves. The methods of sample treatment, and relationship among the breeds were discussed.
