Abstract

To investigate the effects of MS medium strength and nitrogen concentration on bulblet formation from bulblet scale segment culture and bulblet growth from bulblet of Lilium oriental hybrid 'Casa Blanca', asiatic hybrid 'Mona', and longiflorum hybrid 'Hinomoto', 0.5∼2.0 strength of MS salts and 30∼120 mM nitrogen concentrations of MS medium were examined in vitro. The number of bulblets from bulb scale segment was favored in the strength of 0.5∼1.0 strength of MS salts or 30 mM total nitrogen concentration of MS medium in three cultivars. But the growth of bulblets formed in vitro was promoted in the 2 strength of MS medium or hight concentration of total nitrogen of MS medium up to 120 mM in three experimented cultivars.

본 실험에서 Lilium oriental hybrid 'Casa Blanca'. asiatic hybrid 'Mona'와 longiflorum hybrid 'Hinomoto'의 기내 인편으로부터의 자구 형성 및 비대를 위해 MS 배지 내 무기물 농도를 0.5∼2배로, 배지 내 총 질소 농도를 30∼120 mM로 달리하여 자구 형성과 생장을 조사한 결과 인편으로부터의 자구 형성수는 0.5와 1배의 MS 배지 무기물 농도 또는 30 mM의 총 질소 농도에서 'Mona' 품종이 다른 품종에 비해 가장 많았다. 'Casa Blanca'와 'Hinomoto'에서는 0.5배 MS 무기물 농도 또는 30 mM의 질소 농도가 자구 형성에 가장 효과적이었다. 자구 비대는 2배 MS 무기물 농도 또는 120 mM 총질소 농도에서 3품종 모두 양호하였다.
