  • This study was carried out to find out the method of increasing seed germination rate of Dendropanax morbifera LEV. was drupaceous fruit. The length and width of ovarywas 7.8 to 10.7mm, 6.9 to 9.0mm, respectively, and the shape was elliptical. The ovary had 5 loculi with one speed per loculus , but one seed among 5 weeds was exalbuminous seed. The length and width of seed was 6.3 to 7.4mm, 2.0 to2.mm, respectively, and 1,000 seed weight was 14.3 to 18.0g. Seeding after stroring at $10^{\circ}C$ for 60 to 90 days was germinated to 87% . However, fall seeding directly after harvest was increased to 85% at hot-water treatement ($40^{\circ}C$) for 90 to 120 minute.
