Sarcococca ruscifolia belonging to Buxaceae family, it is a wild decorative plant with great exploitive value. The effects of pulp, Method of store, different chemical reagent and temperature on seed germination for Sarcococca ruscifolia were studied. The results showed: the seed germination was inhibited significantly by pulp. 100 mg/L NAA and 0.5% KNO_3 + 100 mg/L GA_3 could significantly improve the seed germination rate. Under 15℃ ,20 ℃ and 20 ℃/15 ℃ ,seed germination rate reached to higher than 90%.
