- W3140139822 abstract "Detopped root systems of Ricinus communis plants were used for the study of the effects of temperature and DNP on the uptake of K and Na ions supplied as KN0 a and l~aN03. When K and l~a ions were offered together in equivalent concentrations, the steady state uptake rates for K + and Na + at 23 to 25 ~ gave a K+/Na + ratio of 3. Increasing the Na+ concentration relative to K + 3-fold did not alter the preferential uptake of K +. The uptake of K + was more sensitive to temperature in the range 10 to 40 ~ and to the application of DNP at 1.5 • 10 -4 M than was the uptake of l~a +. When NaNO a was the only salt supplied Na + uptake became more sensitive to DNP than when both K + and Na + nitrates were supplied. Prolonged application of DNP led to net K+ efflux from the roots, even when no K + was being supplied to the roots. :Net Na + efflux under the influence of DNP occurred only in roots previously grown on l~a-containing nutrient medium. The different responses of the K+ and Na + uptake processes to temperature and DNP suggest the operation of different uptake mechanisms for K+ and Na+ These results have been considered in relation to the recent concept of dual mechanisms for the absorption of alkali cations by plant tissues." @default.
