Abstract

The study was carried out to determine the germination ability of the seeds of halophyte Suaeda salsa, which were treated with various concentration of sodium chloride and natural mixed salt solutions, salinity ranging from 2.93 g/L to 35.1 g/L. For each treatment, rate of germination and of germination recovery were compared. Rate of seed germination decreased as salinity increased and the optimal germination was obtained in distilled water. The natural mixed salinity was less inhibitory than the others to seed germination. After the non-germinated seeds from all the salinity treatments were transferred to distilled water, the finial rate of germination was more than 85% of that of original distilled water control. The results showed that salinity was a reversible osmotic inhibition to seed germination and has no much effect on seed germination ability. The rate of germination recovery increased with an increase of the salt concentration.

Key words
