In Vitro Induction of Adventitious Buds from Leaves and Scale Leaves of Lily Species

The leaves and scale leaves of five lily species were cultivated on MS basic medium, supplemented with different concentration of NAA, 6-BA, TDZ and 2.4-D. The result showed that adventitious buds were induced directly from the leaves when they were cultivated on MS+TDZ 0.5 mg/L or MS+2.4-D 0.2 mg/L+TDZ 2.0 mg/L. The highest induction rate of adventitious bud was 20%. When the scale leaves were cultivated on MS+NAA 0.03 mg/L, MS+NAA 0.05 mg/L and MS+6-BA 2.0 mg/L+2.4-D 0.2 mg/L medium. Adventitious buds were inducted. The induction rate adventitious buds was the highest on MS+NAA 0.05 mg/L medium, theses adventitious buds could bring up new scale bulbs when they were continuously cultured.
