This study was conducted to investigate the characteristics of seed germination pattern by the prechilling and alternating temperature treatments to 16 species of native plant. The seed length, width and thickness ranged from 1.1 to 8.9 mm, from 0.7 to 7.5 mm and from 0.4 to 1.7 mm, respectively. In addition, the 1,000 grain weight of native plants ranged from 0.1 to 8.8g. Germination rate of Melandryum firmum R. and Saussurea pulchella F. with light condition, Capsella bursa-pastoris L. and Leonurus sibiricus L. with dark conditionin of non-treatment were the highest 69, 81,16 and 36%, respectively. Germination rate of Aster scaber T., Cirsium setidens N., Ligularia fischeri T., Plantago asiatica L., and Saussurea sp. of 5$^{circ}C$ prechilling for 30 days were the highest 84, 29, 29, 57, 78 and 95% with light condition respectively, 30% but Cirsium nipponicum M. only with dark condition. Germination rate of Aralia elata S., Aster koraiensis N. and Synurus deltoides N. of alternating temperature with 8 hours at 3$0^{circ}C$ and 16 hours at 15$^{circ}C$ were the highest 2 and 57% with light condition and 52% with dark condition.
