Objective: To study the effects of different hormone induced bulb of Fritillaria cirrhosa seedling leaves, in order to provide an effective way to expant Fritillaria cirrhosa source., Methods: Fritillaria cirrhosa seedling leaves were used as explants, orthogonal test was carried out to study the medium consisting of 6-BA, NAA, 2, 4-D and KT, and proliferation induced by direct bulb. Induction rate and average number of bulb producing was treated as the assessment indices, and the content of alkaloid of bulb was determined., Results: The best medium formula for Fritillaria cirrhosa tissue culture seedling was MS+6-BA 2.0 mg/L +NAA 1.0mg/L +KT 1.0mg/L, the bulb induction rate was 83.37% and the average number of bulb was 17.27. The alkaloid content of induced bulb was 0.389%, which was 1.64 times that of wild Fritillaria cirrhosa bulb., Conclusion: This study provides a simple and rapid mehod for the production of tissue culture of Fritillaria cirrhosa bulb. It is useful for reasonable development and utilization of Fritillaria cirrhosa resources, as well as improvement of the quality of medicinal materials.

Objective: To study the optimal condition for bulb induction of Fritillaria anhuiensis in vitro., Method: Effects of sucrose, salicylic acid, active carbon and 5 degrees C pre-incubation on bulb formation in vitro were investigated by adopting the number of bulb and fresh weight as indexes., Result: The number of bulb and fresh weight in medium added with 50 g x L(-1) sucrose were significantly higher than those with other treatments. The medium with different concentrations of salicylic acid showed no significant promotion on callus differentiation. However, 5 g x L(-1) active carbon (AC) treatment was better than other treatments. Meanwhile, a large number of plantlets formed after 5 degrees C pre-incubation for 30-40 days was suitable for bulb formation and growth., Conclusion: Bulblet formation was optimal in MS + KT 2 mg x L(-1) + NAA 2 mg x L(-1) + 50 g x L(-1) sucrose +5 g x L(-1) AC after callus pre-incucation at 5 degrees 1 for 30-40 days.
