Abstract:

Test-tube bulblet culture is the key technology during the cultivation of lily bulb. To find out the effects of plant growth regulators and sucrose in different concentration on the test-tube bulblet formation, orthogonal test was designed. The result showed that the optimal medium treatment for bulblets induction was MS+0.2 mg/L KT+ 1 mg/L NAA+40 g/L sugar, and the optimal medium for bulb enlargement was 1/2 MS+0.2 mg/L KT+1 mg/L NAA+ 15 mg/L PP333, under which condition the swelling rate was more than 80%, and the optimal medium for rooting was 1/2 MS+0.05 mg/L NAA.
