Abstract:: Taking Scutellaria barbata D.seeds as test materials,the effects of different concentrations of seawater （0%,1%,5%,10%,15%,20%,30%） on Scutellaria barbata D.seeds germination and growth were tested，and the saline alkali tolerance of Scutellaria barbata D.was studied.The results showed that all indexes in the examinations were degraded to varying degrees with seawater concentration increased.Seed germination，germination index within 15% seawater concentration，germination potential within 1% seawater concentration，simplified vigor index，seedling length and root length within 30% seawater concentration were found no significant difference compared with the control.And low seawater concentrations could stimulate the seedling length and root length.Results suggested that the tolerance of low seawater concentrations were observed in Scutellaria barbata D.
