| Abstract: | Germination studies of Cymbopogon schoenanthus (Poaceae) distributed along southern Tunisia were carried out to assess the effects of salinity. A preliminary experiment
showed 30°C as the optimum germination temperature for seeds of this species. After that, seed germination was studied at
different salinity levels. Our results revealed a decrease in germination percentage with increasing salinity. Germination
rate, however, was maintained up to 200 mM NaCl and drastically declined at 300 mM NaCl. |
