Abstract

We describe here an efficient in vitro propagation method of Silene acaulis subsp. arctica (Caryophyllaceae), one of the higher arctic angiosperms, through the multiple shoot regeneration after callus induction from the radicle. The seeds of S. acaulis subsp. arctica collected from Svalbard, the Norwegian Arctic, were germinated and calli were induced from the radicle on solid MS media supplemented with 0.25mg/L 2,4-D and 1mg/L $GA_3$ at both $10{\pm}1^{\circ}C\;and\;23{\pm}1^{\circ}C$ Two weeks after callus induction, the multiple shoots were efficiently regenerated on the MS media supplemented with 0.25 g/L BA and 0.05mg/L HPh. The total biomass increment of regenerated shoots increased most efficiently of S. acaulis subsp. afctica was showed the maximum efficiency in at $23{\pm}1^{\circ}C$ on 1/2 MS salt strength. The multiple regenerated plantlets of S. acaulis subsp. arctics were grown to normal plants on soil.

고위도 북극지역에 분포하는 고등식물인 Silene aoaulis subsp. arctica (Caryophyllaceae)의 유근에서 유도된 캘러스로 부터 다신초를 재분화시키는 방법을 통하여 이 식물의 효율적인 기내 증식 방법을 확립하였다. 북극권 노르웨이령 Svalbard로부터 수집한 S. acaulis subsp. arctica의 종자를 발아시키고 0.25mg/L 2,4-D와 1mg/L $GA_3$가 포함된 고체 MS 배지상에서 $10{\pm}1^{\circ}C$$23{\pm}1^{\circ}C$ 온도조건으로 발아된 종자의 유근으로 부터 캘러스를 유도하였다. 캘러스가 형성된 2주 후부터는 0.25mg/L BA와 0.05mg/L NAA가 포함된 MS 배지에서 재분화가 효율적으로 이루어졌다. 재분화된 다신초들의 총 생체량 증가는 $23{\pm}1^{\circ}C$의 온도와 1/2 MS 배지에서 가장 높은 것으로 나타났다. 기내에서 다신초로 재분화된 식물체는 인공 상토에서 정상적인 식물체로 성장하였다.
