This study was conducted to investigate the suitable conditions for seed germination of Rosa davurica PALL. In the characteristics of the fruit and seed of Rosa davurica, fruit length and width was 1.3cm and 0.9cm , respectively, and seed number was eighty-nine. Artificial and low temperature storage at 4$^{circ}C$ increased the rate of split achene pericarp until 46.6% and storage at 15$^{circ}C$ incubator decreased the rate of split achene pericarp (10.5%). The rate of seed germination of split achene pericarp in control at 15$^{circ}C$ was 90% and of non-split achene in GA$_3$100ppm at 15$^{circ}C$ was 36.8%. Average germination day of split achene pericarp seeds in GA$_3$150ppm at 2$0^{circ}C$ was 4.2 days and non-split achene pericarp in GA$_3$100ppm at 2$0^{circ}C$ was 7.3 days. Seed germination was not different between various concentrations of GA$_3$ treatments in split achene pericarp seeds but the rate of germination was more reduced in high concentration of 200ppm. Only the treatments of GA$_3$ was increased germination rate at 4$^{circ}C$ and immature seed of Rosa davurica.
