Freshly harvested and depulped Korean ginseng seeds were subjected to the seed treatment of removing endocarp plus surface sterilization with sodium hypocloride, surface sterilization only, and nontreated control. These seeds were stratified at temperatures of 5$^{circ}$, 10$^{circ}$, 15$^{circ}$ and 20$^{circ}C$ for 20, 40, 60, 80 and 100 days. Embryo growth of the ginseng seeds of which endocarp was removed was most rapid in each stratification temperature and that of sterilized seeds was slower than unsterilized seeds after 80 days stratification at 15$^{circ}$ and 20$^{circ}C$. About 15$^{circ}C$ was an optimal stratification temperature for embry growth in ginseng seeds. Chilling treatment at 5$^{circ}C$ for 100 days was needed for better germination of dehisced ginseng seeds. An optimal germination temperature for the ginseng seed following chilling treatment was about 15$^{circ}C$.
