摘要: 以白檀(Symplocos paniculata)幼嫩茎段为实验材料, 通过对启动培养、增殖、生根培养及移栽的影响因子进行研究, 初步建立了白檀的组织培养体系。结果表明: 白檀外植体最适灭菌方案为0.1%升汞3分钟, 无菌苗获得率达81%; 最适初代启动培养基为1/2MS+30 g∙L-1蔗糖+8 g∙L-1琼脂, 出芽率达86.83%; 增殖最适培养基为1/2MS+1.0 mg∙L-1 6-BA+0.02 mg∙L-1 IBA+30 g∙L-1蔗糖+8 g∙L-1琼脂, 增殖系数达3.57; 最适生根培养基为WPM+0.5 mg∙L-1 IBA+0.5 mg∙L-1 NAA+20 g∙L-1蔗糖+2 g∙L-1 AC+8 g∙L-1琼脂, 生根率达93%; 炼苗后, 移入园土:草炭土=1:1 (v/v)的基质中, 成活率达83%。
