This experiment was conducted to investigate the mass propagation system of Aster glehni FR. and to obtain the basic data for improvement of germination and seedling. The following was the results of experimentation about temperature and light conditions, and priming treatment as kinds of chemicals, their concentration and treated periods affect germination of Aster glehni FR. The germination percentage of Aster glehni FR. seed was higher in 20 and 25$^{circ}C$ than the others, but it dropped rapidly at 30$^{circ}C$ and didn't germinate at 35$^{circ}C$. The first day to germination was the slowest at 15$^{circ}C$. The germination rate of Aster glehni FR seed increased with increasing with temperatures from 15 to 25$^{circ}C$. But the seed was rotten easily in high temperature. The germination rate was shown highest in 25$^{circ}C$, and next was 15, 20, 30$^{circ}C$ in order. Light treatment enhanced germination percentage, the first day to germination, germination rate and T50, but there was no significant difference. The 3 hours priming treatments had more effect on germination percentage than 30 minutes treatments as comparing averages. Aster glehni FR seeds primed in $KNO_3+K_3PO_4$ for 3 hours had most eHective on germination percentage (83.3%) and also showed shortest $T_{50{cdot}}T_{50}$ and day of first germination was better in 30 minutes than 3 hours treatments, and most of priming treatments were better than control(non-priming seeds). While priming seeds showed shorter day of first gemination than control, there was no significant difference between 30 minutes and 3 hours treatments.
