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 mid-portion of a leaf than that in stems. The high enzyme activities were observed in mid-bottom stems in the half-bred plant, and the activity was higher in bottom leaf than that in mid-top leaf.

结果表明：3个裙带菜群体的POD同工酶其孢子叶活力都相对强于其它部位；日本裙带菜茎和叶的各部位POD酶活力相同，但叶中部的酶活力稍强于茎；自育裙带菜茎底部和茎中部的POD酶活力较强些，而叶底部的酶活力较叶中部和顶部的强；本地裙带菜的茎和叶由底部到顶部POD酶活力逐渐变弱。
