摘要
为建立细叶百合离体快繁的再生体系,对细叶百合组培苗的继代培养、生根培养及移栽条件进行了研究。结果表明:继代培养在MS+6-BA 2.0 mg/L+NAA0.1 mg/L上培养基上鳞茎的增殖系数为6.95,且苗粗壮、长势良好;生根培养在1/2MS+IBA 0.5 mg/L生根最快,生根率达100%,根粗壮,平均每个小鳞茎生根8.77条,平均根长为2.85 cm,苗长势较好;移栽基质以泥炭土效果最好。
This research was to study the sub culture condition for the rapid propagation of low lily （Lilium pumilum DC. ） in vitro. The subculture and root induction technique of low lily were studied. The results showed that the suitable medium for subculture was MS with 6 - BA 2.0 mg/L and NAA 0.1 mg/L. The multiplication coefficient of bulb was 6.95 and the seedling grew very well.The suitable substrates for rooting were 1/2 MS with IBA 0. 5 mg/L and the rooting rate reached 100%. The Rooting number reached 8.77 strips in every small bulb and the rooting length could reach 2.85 cm.Peat soil was the best transplanting substrate.
