把“荷兰雪球4号”优选单株的花球组织切段,在MS基本培养基加BA 0.5mg/l及NAA 0.5mg/l或BA 0.2mg/l及NAA 1.0mg/l的固体培养基中,培养25天即获得完整植株(试管苗)。只用同种培养基即可诱导产生芽及根,成活率达92％以上。把高4～5厘米、根长2厘米左右的试管苗移栽到塑料移植箱中,移栽成活率达60％左右。
The “Holland Snowball No.4”, which is the preferred plant bulblets, was cut into sections and cultured on MS basal medium with BA 0.5 mg / l and NAA 0.5 mg / l or BA 0.2 mg / l and NAA 1.0 mg / l Base, cultivate 25 days to get the whole plant (test tube seedling). Only the same medium can be induced to produce buds and roots, the survival rate of 92% or more. The high 4 to 5 cm, root length of about 2 cm in vitro transplanted into plastic transplants, transplanting survival rate of 60%.
