Abstract The germination rate of seeds from two local populations of Salicornia bigelovii Torr. are evaluated. Seed samples were obtained from Sonora and Baja California Sur, Mexico, and were germinated under various salinity concentrations of diluted sea water. The seeds from Sonora germinated at a faster rate than the ones from Baja California. Highest percentage of germination was obtained under non-saline water conditions together with a considerable reduction in germination as concentrations were increased; germination rates were reduced considerably when salinity concentrations were increased for both populations. No statistical differences were found between the mean values of germination after the nineteenth day of the experiment for both ecotypes. A positive correlation was found between low levels of salinity (9 ppm of total dissolved solids) with total length and dry matter of seedlings. It is concluded that salinity levels which are equal to or higher than 18 ppm (50% of sea water) inhibit and reduce the germination rate of both populations. These results explain the high emergence of seedlings found in field conditions just after the rainy season occurs.
