Higher and uniform germination should be necessary because many commercial pepper (Capsicum annum L.) seedlings were nowadays sold to farmer. The experiment was carried out to determine the effect of its cultivars (Daemyung; Wanggochu), GA$_3$ (concentration; period), light quality (red; far-red; blue; dark) during GA$_3$imbibition, and germination temperature (GT: 25 or 15$^{circ}C$ constant; 25/15$^{circ}C$ alternating) on the rate of germination done under incandescent lamps until 9 days after sowing. Final seed germination was not different between GA$_3$0 to 1.0 mM concentrations but the elapsed days to 50% germination $(T_{50})$ were more reduced by GA$_3$ treatment than water imbibition. Under $25^{circ}C$ constant germination temperature, earlier germination was enhanced by GA$_3$treatment showing the lowest rate at darkness, although the final germination rates of water imbibition and GA$_3$ treatments were same. The final germination rates of alternating and 25 $^{circ}C$ constant GT in cv. Daemyng was also equal, while the germination rates of $25^{circ}C$ and 15$^{circ}C$ constant GT were the highest and the lowest regardless of cultivars. There was no difference between light quality treatments impelled during GA$_3$ imbibition when light treated seeds were germinated at alternating and $25^{circ}C$ constant GT. At 15$^{circ}C$ constant GT, however, red light or dark treatment during GA$_3$imbibition increased the germination rate since 5 days after sowing.
