Conteúdo: | Using a split-root technique, it was possible to demonstrate an internal inactivation of Fe in PI-54619-5-1 soybenas (PI), principally from the combined effects of P and Ca. Ca stimulated root growth, increased the absorptions and translocation of P and Ca to the above-ground parts, but decreased the absorption and trans location of Fe in the presence of P. A varietal difference in susceptibility to induced Fe deficiency was gain observed. Hawkeye soybean (HA) remained green under conditions which induced Fe chlorosis in PI. This indicates a difference in the capacity of these two soybean varieties to absorb and hold Fe mobile in an environment which appears conductive to inactivation. Both foliar applied and soil Fe were affected. Quantity or quality of natural iron chelators in the plant is postulated as the factor responsible for this difference.
