A comparison of potassium translocation in excised roots and intact maize seedlings.
The water and potassium fluxes exuded by excised primary roots of maize seedlings are compared with the rate of wet weight increase and of potassium uptake by the growing tissue of the shoots of intact seedlings. The exuded potassium flux from 1 mM KCl solution as the bathing medium is found to correspond very closely to the potassium uptake by the shoots of seedlings of idenfical age and history as the excised roots.
