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.

Keywords: Chenopodiaceae; compatible osmotica; halophyte; HPLC; salt tolerance
Subjects: Atriplex prostrata; glycinebetaine accumulation, Na and K salts, osmotic potential; halophytes, glycinebetaine accumulation; osmotic potential, glycinebetaine accumulation, salt stress; potassium, glycinebetaine accumulation; salt tolerance, glycinebetaine accumulation; sodium, glycinebetaine accumulation
