Summary
Na-, K-, and Ca-uptake by excised barley roots from solutions containing two of the chloride salts at constant ionic strength of 1 m mol/l and different cation proportions were investigated. Na-content followed a linear course as a function of concentration and was independent of the associated ion whether it was K or Ca. K and Ca did not follow the same trend and K increased Ca-uptake indicating that K and Ca take part in forming one carrier complex molecule. The importance of the initial cation content of roots in determining cation uptake is stressed.
