Corn plants, grown in sand and watered with Hoagland's nutrient solution, accumulated large quantities of lead when the lead was applied to sand as lead nitrate. The quantity of lead accumulated depended on the amount applied, the status of the plant with regard to phosphate, and the age of the plant. Higher quantities of applied lead inhibited plant growth. Experiments with mitochondria isolated from corn shoots showed a lead induced inhibition of succinate oxidation and a lead induced stimulation of NADH oxidation. These experiments also demonstrated that the phosphate regime of the mitochondria is important in lead affected oxidative reactions. A site of lead activity in corn mitochondrial oxidations seems to be associated with some of the flavoproteins of electron transport.
