초록

도라지(Platycodon grandiflorum (Jacq. A. DC.)에서 신초발생에 대한 최적의 호르몬 조건을 조사하기 위하여 잎 및 배축절편을 1.0 mg/L 2,4-D와 0.1, 0.5, 1.0, 2.0 mg/L BA 또는 kinetin과 각각 조합 첨가한 MS 기본배지에 6주 동안 명 배양 하였다. 배양절편에 따라 신초발생율은 잎 절편에서 56.38%로 배축절편(28.20%)보다 높았다. Kinetin과 BA를 2,4-D와 조합첨가 하였을 때 kinetin의 경우 잎에서 70.38%로 BA (42.38%)보다 더 효과적이었으며, 반면 BA의 경우 배축에서는 35.56%로 kinetin (20.83%)보다 더 높은 빈도를 보였다. 가장 높은 신초형성 빈도(94.20%)는 1.0 mg/L 2,4-D와 1.0 mg/L kinetin이 조합첨가된 MS 배지에서 잎 절편을 배양하였을 때 얻을 수 있었다. 대부분의 신초는 1/2 MS기본배지에서 뿌리를 유도한 후 토양에서 완전한 식물체를 얻을 수 있었다. 이러한 결과는 최적의 기내배양 조건을 통해 도라지의 대량생산 가능성을 보여주었다.

To investigate optimal conditions for plant regeneration in Platycodon grandiflorum (Jacq. A. DC.).Both leaf and hypocotyl explants were cultured on Murashige& Skoog's (MS) medium supplemented with combinations of 0.1, 0.5, 1.0, or 2.0 mg/L cytokinins (BA and kinetin) and 1.0 mg/L 2,4-D for 6 weeks, respectively. According to the type of explant, the total shoot organogenesis (56.38%) in leaf explants was higher than in hypocotyls (28.20%). In comparison with kinetin and BA for the plant regeneration, the frequency (70.38%) of leaf explants was higher in combination with kinetin and 2,4-D than of BA with 2,4-D (42.38%), whereas the frequency (35.56%) of hypocotyls explants was higher in BA combination than kinetin combination (20.83%). Thehighest frequency (94.20%) was observed from the cultures of leaf explants on the MS medium supplemented with 1.0 mg/L kinetin and 1.0 mg/L 2,4-D. Upon transfer onto 1/2 MS basal medium containing 3% sucrose, shoots developed into plantlets with roots, and were well grown in soil in the greenhouse. These results lead us to speculate that the optimization of culture conditions was responsible for the mass propagation from in vitro cultures of Platycodon grandiflorum (Jacq. A. DC.).
