초록

본 연구는 기내에서 발아된 까마중 유식물체의 조직별로 신초 및 뿌리 유도를 통해 효율적인 재분화 조건을 확립하고자 실시하였다. 신초 형성은 식물체 부위별로 서로 달랐으며, 잎에서의 신초 형성빈도가 자엽이나 하백축 그리고 상배축보다 높았다. 절편체당 신초의 수는 잎과 자엽에서 다소 많았으며, 신초의 길이도 다른 부위에 비해 잎과 자엽에서 빠른 증식과 신장을 나타내었다. 특히, 2.0 mg $L^{-1}$ BAP가 첨가된 배지에서 재분화율, 신초의 수와 길이가 증가하여 2.0 mg $L^{-1}$ BAP가 고빈도 신초의 유도 및 생장에 효율적인 것으로 판단되었다. 뿌리분화는 IBA와 IAA가 NAA보다 더 효과적인 것으로 나타났으며, 0.05 mg $L^{-1}$ IAA가 첨가된 배지에서 뿌리 형성율이 90%이며, 뿌리의 갯수와 길이도 각각 평균 4.0개와 7.82 cm로 가장 양호하게 나타났다. 더욱이 배양토에 이식한 재분화체는 100%의 생존율을 보였으며 정상적인 식물체로 생장하였다. 이러한 결과를 토대로 2.0 mg $L^{-1}$ BAP 조건에서의 잎 절편에서 다발성 신초 유도, 그리고 0.05 mg $L^{-1}$ IAA 조건에서의 뿌리형성 유도가 까마중의 대량번식을 위한 최적의 조건임을 알 수 있었다.

In the present study, the effects of plant growth regulators on adventitious shoot and root formation of various explants of $in$ $vitro$ seedlings of $Solanum$ $nigrum$ L. were investigated to determine the optimum conditions for the high-efficiency plant regeneration of this species. The formation of adventitious shoots was higher in leaf explants than in cotyledon, hypocotyl, or epicotyl explants at low concentrations (0.5~2.0 mg $L^{-1}$ ) of 6-benzylaminopurine (BAP). The number of adventitious shoots and the shoot length were also higher in both leaf and cotyledon explants. In particular, 2.0 mg $L^{-1}$ BAP was most effective for stimulating the induction and multiplication of adventitious shoots. In terms of root formation and root development from shoots that were separated from multiple shoots, indole butyric acid (IBA) and indole acetic acid (IAA) were more effective than ${\alpha}$-naphthalene acetic acid (NAA). The percentage of rooting as well as the number of roots per shoot (4.0), root length (7.82 cm), and shoot length (8.76 cm) was highest on MS media supplemented with 0.05 mg $L^{-1}$ IAA. Furthermore, 100% of the regenerated plantlets survived when transplanted to compost soil. These results suggest that leaf explants are the best source for the high-efficiency regeneration of $S.$ $nigrum$ L., and that 2.0 mg $L^{-1}$ BAP and 0.05 mg $L^{-1}$ IAA are the best conditions for shoot and root induction, respectively.
