Tissue culture and rapid propagation of Lilium asitic hybrids cv. Prato

The rapid propagation technique was studied in Lilium asitic hybrids cv. Prato with the bulb scales and leaves in vitro as explants and MS as basic medium with different hormones and concentrations. The results showed that the best medium for adventitious bud induction from bulb scales and leaves was MS+0.5 mgL-1 6BA+0.1 mgL-1 NAA, with which the highest induction rate was 85.0%, and the average number of shoots from every explant was 3.6. The best medium for adventitious buds induced from bulb scales was MS+1.0 mgL-1 6BA. The optimum medium for taking root was 1/2 MS+0.5 mgL-1 IBA，and the rooting rate was 86.7%. The transferred plants, with a survival rate of 85.0%, grew well.
