3个百合品种的鳞茎诱导试验

通过试验比较了MS+6-BA+NAA培养基对3个百合品种丛芽诱导、丛芽扩增的效应,比较了以MS为基本培养基,添加不同浓度的蔗糖后,构成不同的鳞茎诱导培养基的效应,得出了适宜蔗糖添加浓度.结果显示:(1)在相同丛芽诱导培养基下,不同百合品种的丛芽诱导率不同.白百合为28.00%,麝香百合为22.67%,香水百合为25.33%;(2)在相同丛芽扩增培养基下,不同百合品种的丛芽增殖率也不同.香水百合的增殖率最高,其次是麝香百合,白百合最低.(3)在所供试的鳞茎诱导培养基中,蔗糖浓度为4%时白百合和麝香百合的鳞茎诱导效果最好,而浓度为3%时最有利于香水百合的鳞茎诱导.

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 %.
