宜兴百合鳞茎不定芽的诱导及增殖
Hubei Agricultural Sciences（2014）
Abstract
以宜兴百合(Lilium lancifalium Thunb.)鳞片为外植体诱导小鳞茎的形成,并通过正交设计增殖鳞茎不定芽.结果在MS+1.0 mg/L 6-BA+ 0.1 mg/L NAA培养基上,鳞片以直接发生方式形成了鳞茎不定芽,诱导率为100％,平均不定芽数为5.5.6-BA浓度在0.4～1.2 mg/L范围内,鳞茎不定芽的增殖率随6-BA浓度的升高而增大,在MS+1.2 mg/L 6-BA +0.2 mg/L IAA +0.1 mg/L NAA培养基上,不定芽的增殖系数为3.83,不定芽在1/2MS+1.0 mg/L NAA培养基上生根良好.
