초록

아마릴리스 'Picottee', 'White Christmas', 'Eldorado', 'Origin', Red Lion', 'Telstar', 'Crypsy'의 교잡배를 여러 농도의 2,4-D, NAA, BA, TDZ가 첨가된 MS배지에 배양한 결과, 0.5～3.0 ㎎/L 2,4-D에 비하여 0.5～3.0 ㎎/L NAA 처리구에서 줄기와 자구 분화가 양호하였다. 0.5㎎/L NAA 처리는 배양체로부터 높은 자구 형성율을 나타냈고, 줄기 분화율은 NAA 1.0㎎/L과 TDZ 2.0㎎/L 혼용처리구에서는 가장 높았다. 배지에 1.0～2.0㎎/L TDZ 첨가는 치상체당 더 많은 줄기를 분화시켰으나 1.0～2.0㎎/L BA 처리보다 뿌리의 발달은 억제되었다. 'Star Van Holland'의 인편을 배양했을 때 자구 형성은 0.5㎎/L NAA가 첨가된 배지에서 가장 효과적이었다.

Immature hybrid embryos of H. hybridum, 'Picottee', 'White Christmas', 'Eldorado', 'Origin', 'Red Lion', 'elstar', 'Crypsy' were cultured on the MS medium supplemented with various concentrations of 2,4-D, NAA, BA and TDZ. Among the treatments, NAA were more effective for the shoot regeneration and bulblet formation than other treatment. Addition of 0.5 ㎎/L NAA was effective for bulblet induction from explant Shoot regeneration was most effective on the medium with 1.0㎎/L NAA and 2.0 ㎎/L TDZ. The addition of 1.0-2.0㎎/L TDZ induced numerous shoots per explant but strongly inhibited root development when compared to 1.0-2.0㎎/L BA. When bulb scale segments of 'Star Van Holland' was incubated, bulblet formation was the most effective on MS medium with 0.5㎎/L NAA.
