Plants of Oh43 ✕ Wf9 corn ( Zea mays L.), grown in sand culture system, were watered daily with nutrient solution containing 0.025, 1.25, or 2.5 ppm Fe. Plants also were grown in a soil‐sand mixture. Leaf extracts were assayed quantitatively for peroxidase activity, and sampies of the extracts were subjected to gel dectrophoresis. A positive relationship was observed between Fe supply and proxidase activity. Numerous peroxidase isozymes were detected by gel electrophoresis. As judged by intensity of the hands, all isozymes appeared to be influenced by Fe supply.
