Phosphorous levels on the ability of an iron‐inefficient and an iron‐efficient corn inbred to take up iron from nutrient solution

Abstract

The Fe‐inefficient corn (Zea mays L.) inbred Ys₁/YS₁ was compared with the Fe‐efflcient WF9 inbred for ability to take up Fe from solution culture at different P levels. A high level of P depressed Fe uptake more in the Ys₁/Ys₁ than in the WF9 inbred. The Ys₁/Ys₁ roots were high in P.
