13 Root Zone and Drought Tolerance SOME BIOCHEMICAL ASPECTS OF ION UPTAKE BY ROOTS Euripedes Malavolta, Universidade de Sao Paulo, Sao Paulo, Brazil The main aspects of ion uptake, such as carrier concept, kinetics, and energy relationship, were described. The fundamental importance of such concepts for the understanding of plant nutrition was stressed.
