| Abstract | The impact of salinity (0-400mM NaCl) on the germination of four Tunisian accessions (Tabarka, Mahdia, Sfax, and Jerba) of the halophyte Cakile maritima was assessed. Moderate salinity (50-150mM NaCl) slightly inhibited the germination of Sfax, Mahdia, and Jerba seeds, since more than 75% of the sown seeds germinated. Salt adverse impact was more pronounced in Tabarka seeds, which showed significantly less germination capacity, even under salt-free conditions (40%). Although increasing salinity drastically inhibited the germination in Tabarka, Sfax was the most tolerant accession, especially at 200-300mM sodium chloride (NaCl). Assessing germination kinetics using a mathematical model indicated that high salinity impaired and delayed the germination process. Such an effect resulted from the combination of osmotic and toxic components, especially at the greatest concentrations (300-400mM NaCl). These findings point out that the successful establishment of this halophyte at the earliest ontogeny stages is both accession- and salt-dependent. |
