Abstract

This study was performed to enhance the proliferation rate of Gladiolus 'Topaz' callus. The callus was induced from the cermet tissue explants on MS solid medium with 10 mg/L 2,4-D. In the case of liquid shaking culture, proliferation of the callus was effective in MS medium with 0.05 mg/L 2,4-D at 2$0^{\circ}C$ under 16 hours daylength and in a 100 mL Erlenmeyer flask containing 20 mL of the liquid medium and at 75 rpm in rotation speed of the horizontal shaking culture. Furthermore the callus was also able to be subcultured in the same liquid medium.

본 연구는 글라디올러스 Topaz'를 재료로 액체진탕배양에 의한 캘러스의 증식효율을 향상시키기 위하여 수행되었다. 캘러스는 2,4-D 10mg/L가 첨가된 MS고체배지에 목자 외식체를 배양하여 유도하였다. 액체진탕배양에 의한 캘러스의 증식은 2,4-D 0.05 mg/L가 첨가된 MS배지를 사용하여 2$0^{\circ}C$, 16시간 일장하에서 배지를 100 mL 삼각플라스크에 20 mL 분주하고, 수평회전식 진탕배양기의 회전속도를 75 rpm으로 하였을 때 증식속도가 가장 빨랐다. 또한 동일 배지에서 캘러스의 계대배양 역시 가능하였다.
