Abstract: Ceratoides lanata (Pursh) J. T. Howell is a shrub with numerous annual branehlets from the Chenopodiaceae family and is widely distributed in brackish water playas of northern Utah. Seeds had no dormancy, and about 90% of the seeds germinated in nonsaline control. Seed germination decreased with the increase in salinity,and more than 10% of the seeds germinated at 900 mmol/L NaC1.Almost all seeds germinated in less than 24 h, and no additional seed germinated after this time. Gibberellic acid had no effect in alleviating salinity effects;however, kinetin and fusicoccin substantially alleviated the effect of salinity on germination, while ethephon almost completely reverted the effect of salinity.
