RESUMO
Nitrate uptake of Na+ -deficient Amaranthus tricolor L. cv Tricolor seedlings from complete culture solution was stimulated by about 210% within 5 hours by application of 0.5 millimolar NaCl. From a Na+ -preloading experiment, intracellular Na+ was shown to be responsible for the stimulation of NO3− uptake. The results suggest a possible role of Na+ in NO3− uptake in C4 plants.
