Experiment on Bulb Inducement of Lily Cultivars

Effect on the shoot abduction and shoot proliferation of three varieties of lily in the same medium was tested and MS was chosen as the basic culture medium with 6-BA、NAA suc-rose of different concentrations in order to find the optimum concentrations of sucrose for bulbs in-ducement.The optimum medium of three varieties of lily bulbs induced was chosen by using the base of squama.Results indicated that:(1) The same shoot induction medium can take a different effect on shoots inducement rate of varieties of lily.Rate of shoot abduction for Lilium candidum was 28.0 %,rate for Lilium longiflorum was 22.7 %,and rate for Lilium Casa Blanca was 25.3 %;(2) The same shoot proliferation medium can take a different effect on shoot proliferation rate of varieties of lily.The rate for Lilium Casa Blanca was the highest,rate for Lilium longiflorum was lower,and rate for Lilium candidum was the lowest;(3) In the bulb inducement medium test,the optimum concentrations of sucrose for Lilium candidum and Lilium longiflorum is 4 %,and the op-timum concentration of sucrose for Lilium Casa Blanca is 3 %.
