Simultaneous Influx and Efflux of Nitrate during Uptake by Perennial Ryegrass

, : Simultaneous Influx and Efflux of Nitrate during Uptake by Perennial Ryegrass. Plant Physiology 51(2): 267-272

In solution culture experiments there was significant efflux of (a) 14N-labelled nitrate ion from intact plants of perennial ryegrass previously grown in solutions containing (a) when transferred to solutions of (b) 15N-labelled nitrate ion. Efflux from the roots continued if the external solution was renewed, but (a) was reabsorbed if it was not. In solutions of the same nitrate content, uptake of (b) was greater than that of (a).
