The effect of different salts of sodium and potassium on the accumulation of glycinebetaine in Atriplex prostrata

Abstract

Atriplex prostrata was grown for one month in nutrient solutions with NaCl, KCl, Na2SO4, and K2SO4 (at osmotic potentials of 0, -0.75, -1.00, and -1.50 MPa). Plants treated with K2SO4 had less glycinebetaine at -1.0 and -1.50 MPa than those treated with Na+ salts, probably due to the inhibitory effects of K+ on glycinebetaine accumulation.
