The tissue culture and plant regeneration of Bolbostemma paniculatum were studied and a large number of regenerated plantlets were obtained. The optimal compounding of medium that induced calli from stems and leaves were the MS medium supplemented with 2,4-D 2.0 mg/L, NAA 0.5 mg/L and BA 1.0 mg/L and the MS medium with 2,4-D 0.5 mg/L and NAA 2.0 mg/L, respectively. Numerous shoots could formed directly when leaf explants were cultured on the MS medium with BA 3.0 mg/L and NAA 1.0 mg/L and calli were cultured on the MS medium with BA 2.0 mg/L and IAA 1.0 mg/L. The MS medium supplemented with BA 2.0 mg/L, IAA 0.1 mg/L was optimal for shoots growth. For the root growth was 1/2 MS medium with 1.0 mg/L IBA. At pH 6.0 and 0.8% - 1.0% agar was optimal for callus and shoot formation, while pH 5.8 and 0.6% - 0.7% agar was optimal for root formation. The tube seedling can be successfully transplanted.
对假贝母的组织培养和植株再生进行了研究,并获得了大量再生植株。诱导茎和叶产生愈伤组织的培养基最佳配方分别是添加2.0 mg/L 2,4-D、0.5 mg/L NAA和1.0 mg/L BA的MS培养基以及添加0.5 mg/L 2,4-D和2.0 mg/L NAA的MS培养基。当叶片外植体在添加3.0 mg/L BA和1.0 mg/L NAA的MS培养基上培养,愈伤组织在添加2.0 mg/L BA和1.0 mg/L IAA的MS培养基上培养时,可直接形成大量芽。添加2.0 mg/L BA和0.1 mg/L IAA的MS培养基对芽的生长最为适宜。对于生根,以添加1.0 mg/L IBA的1/2 MS培养基为宜。pH值为6.0、琼脂含量为0.8% - 1.0%对愈伤组织和芽的形成最为适宜,而pH值为5.8、琼脂含量为0.6% - 0.7%对生根最为适宜。试管苗能够成功移栽。
