Abstract
The C4 speciesFlaveria trinervia is obviously better adapted to saline environments than the C3 speciesF. pringlei. Treatment with 100 mM NaCl diminished crop growth rate inF. pringlei by 38% but not inF. trinervia. Under saline conditions, more assimilates were invested in leaf growth inF. trinervia but not inF. pringlei. Electrolyte concentration inF. trinervia in control and salt treated plants is lower than inF. pringlei. Fluorescence data do not indicate a damage of PS 2 charge separation in both species. Whether the C4 photosynthetic pathway inF. trinervia is responsible for the improved salt tolerance compared toF. pringlei remains an open question.
