Sodium relations in desert plants: 7. Effects of sodium chloride on Atriplex polycarpa and Atriplex canescens
Atriplex canescens (Pursh) Nutt. ssp. canescens (Caligonum c. Pursh.) and Atriplex polycarpa (Torr.) Wats. (Obione p. Torr.) plants were grown in Yolo loam soil in a glasshouse with different levels of sodium salts. Both species tolerated concentrations of salt equivalent to seawater, using either NaCl or Na/sub 2/SO/sub 4/. Vegetative yields were sightly higher with chloride, particularly with stems of A. polycarpa; SO/sub 4//sup 2 -/ decreased calcium and magnesium concentrations. Atriplex canescens leaves contained less Na, total cations, Cl, S, and Si, but more N than did those of A. polycarpa. The A. polycarpa would have high concentrations or organic acids in leaves. Chloride decreased N concentrations in leaves of A. polycarpa.
