Abstract: An experiment was carried out on the induction of bulbulets and the plant regeneration by
using the ovaries of Cardiocrinum giganteum as exp lants. The results indicated that BA and KT were the main
factors in ovary explant differentiation. The explants differentiated into calluses when the concentration of BA
and KT was between 0.1 and 1.0 mg/L and budswere induced when the concentration was bewteen 2.0 and
4.0 mg/L, and when higher than 4.0 mg/L, leaves formed. The best basic media for the dedifferentiation
were N6 and B5. The bestmedium for bulbulet induction from calluswasMS + 0.1 - 0.5 mg/L NAA + 2.5
mg/L BA + KT 2.5 mg/L + 10% sucrose + 0.7% agar. The ratio of root induction from calluswas 100% on
the medium of 1/2MS + 3% sucrose + 0.7% agar + 1% active carbon. After acclimatization for one week,
the bulblets were transp lanted into greenhouse and all grew well.
