The plant habitat is moved by change of growth environment due to global warming. And it have to need seed germination and successful settlement of seedling in new habitat. This study aims to supply basic data for predicting change of habitat of Dendropanax morbifera Lev., warm temperate tree in Korea, by global warming. Characteristics of seed germination of D. morbifera was studied in different temperature and light conditions. Firstly, fruit and non-fleshed seed were saw without cold

After cold treatment at 4°C, non-fleshed seed shows high germination ratio of 87%, 53%, 77%, 63%, 23% in 10°C, 15°C, 20°C, 25°C, and 30°C, respectively. Also, in filed test, non-fleshed seed was high in 69.2% and in non-light condition. However, it did not shown germinated seed in light condition. In conclusion, germination of D. morbifera mainly controlled by non-light condition in temperature after cold treatment for about 3 months on 4°C.
