Abstract

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.

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.
