Abstract

Experiments were carried out in order to study the effect of time external concentration, pH, temperature, aeration and inhibitors (KF, KCN and 2,4-DNP) on the phosphate absorption by the excised roots of grain Sorghum bicolor L. Moench var. Contibrasil 102, DeKalb and Tey-101, using 32P as tracer.
