Abstract
Sodium chloride (NaCl) concentrations 200 to 900 mM enhanced the photo synthetic rate (P(N)) both in whole leaves and in mechanically isolate d, intact mesophyll cells of a salt marsh halophyte Sesuvium portulaca strum with a maximum at 600 mM NaCl. These changes were in agreement w ith changes in chlorophyll concentration in leaves. Though the increas ing salt concentrations resulted in leaf succulence, no change in the photosynthetic carbon pathway was observed.
