Abstract
When soybeans (Glycine max L. Merr. Bragg) were grown in solution culture, the PI54619–5–1 cultivar was Fe‐deficient when the Zn level was 10‐4 M. Iron contents in leaves were reduced by the high Zn level in the Hawkeye cultivar but less so than with the PI54619–5–1 cultivar. The high Zn resulted in depressed Fe contents in leaves, stems, and roots of both cultivars and in some direct effects of Zn toxicity with the Hawkeye cultivar. A high level of FeEDDHA (ferric ethylenediamine (di(o‐hydroxy‐phenylacetic acid)) partially overcame the Fe deficiency induced by a high Zn level.Keywords
