초록

본 연구는 우리나라 주요 재배종인 Muscari armeniacum 'Early Giant' 품종을 사용하여 엽절편체로부터 직접적으로 신초재생과 체세포배 발생에 미치는 생장조절제의 효과를 구명하였다. 무스카리의 엽조직으로부터 캘러스 과정을 거치지 않은 직접 신초형성은 2,4-D $0.1mg{\cdot}L^{-1}$가 함유된 배지에서 가장 좋았다. 반면, 체세포배 발생은 생장조절제를 첨가하지 않는 대조구와 IPA $0.1{\sim}1.0mg{\cdot}L^{-1}$가 함유된 농도의 배지에서 비교적 양호하였다. 무스카리의 엽조직으로부터 재생된 자구를 기외로 이식했을 때 맹아율은 모든 처리구에서 80%이상으로 높았으며 특히 NAA $0.1mg{\cdot}L^{-1}$, IPA $1.0{\sim}3.0mg{\cdot}L^{-1}$ 배지에서 재생된 자구의 생장이 양호하였다.

This experiment was carried out in order to determine proper plant growth regulators (PGR) and their concentrations for direct shoot induction and somatic embryogenesis from leaf tissue cultures of Muscari armeniacum 'Early Giant'. Direct shoot formation from the leaf explant culture was effective only on a half-strength MS medium containing $0.1mg{\cdot}L^{-1}$ 2,4-D, while embryogenesis was occurred on a half-strength MS medium containing $0.1{\sim}1.0mg{\cdot}L^{-1}$ IPA or without PGR. The regenerated bulblets derived from embryos or shoots were harvested and transplanted into a greenhouse. The sprouting percentage of bulblets obtained from different culture media ranged from 80 to 100% and growth of quality bulblets was enhanced when the bulblets were harvested from the medium containing $0.1mg{\cdot}L^{-1}$ NAA and $1.0{\sim}3.0mg{\cdot}L^{-1}$ IPA.
