Abstract
Plants of Oh43 X Wf9 corn (Zea mays L.), grown in a 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 samples of the extracts were subjected to gel electrophoresis. 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 bands, all isozymes appeared to be infIuenced by Fe supply.
