EFFECT OF CARBONYL CYANIDE PHENYLHYDRAZONE ON CATION UPTAKE IN EXCISED BARLEY ROOTS

Abstract
The generally-accepted characteristics of ion transport in plant tissue do not apply completely in the case of zinc uptake. In this case, 5×1−5m CCP (which completely stops rubidium uptake in barley roots) shows little inhibitory effect. In this respect it is like DNP which also shows little influence on zinc uptake in this concentration.
