Abstract:: To further understand the seeds germination characteristics of Saposhnikovia divaricata(Turcz.) Schischk，seeds stored up two years were treated using different concentrations of KNO₃,H₂O₂,GA₃ to test seeds germination characteristics.The results showed that 0.3%H₂O₂ and 3.0%H₂O₂ promoted the germination the best，germination rate were higher than the control increased by 48.97% and 51.03%，germination potential were higher than the control increased by 35.24% and 51.70%.20.0，0.8 mg/kg GA₃，0.05，0.10 mol/L KNO₃ and 30% H₂O₂ played an inhibition role in seed germination.The 0.10 mol/L KNO₃ restrained the strongest，germination rate was 96.51% lower than the control group.
