Maximum growth over a period of 3 months of Atriplex hymenelytra (Torr.) Wats. (desert holly) in solution culture was obtained when the nutrient solution contained 5 x 10/sup -2/ N NaCl. Sodium concentratons in leaves at maximum yield was 7.88% and that of Cl was also 7.88%. In the presence of 10/sup -2/ N Na/sub 2/SO/sub 4/, there was much less growth than with 10/sup -2/ N NaCl. The highest NaCl level depressed levels of K, Ca, and Mg in leaves, stems, and roots. The highest NaCl level also decreased levels of micronutrients in many of the plants.
