摘要: 以野生花卉植物绶草的肉质根、幼叶、花序轴为外植体,建立组织培养快繁体系。试验结果显示:绶草组织培养较理想的外植体材料为花序轴,诱导率达到83%;最适诱导培养基为MS+3.0%蔗糖+0.75%琼脂+6-BA1.0mg/L+NAA0.1mg/L;最适增殖培养基为MS+3.0%蔗糖+0.75%琼脂+6-BA2.0mg/L+NAA0.2mg/L+椰汁100g/L;最适生根培养基为1/2MS+2.0%蔗糖+0.5%琼脂+IBA0.5mg/L+NAA0.5mg/L+活性炭0.5g/L。

Abstract: Using fleshy root, young leaf and rachis of wild flower Spiranthes sinensis as explant, the rapid propagation was constructed with tissue culture in the study. The results showed the induction rate with using rachis as callus reached 83 %, the medium compositing of 3.0 %MS sucrose, 0.75 % agar, 1.0 mg/L 6-BA, 0.2 mg/L NAA and 100 g/L coconut juice was the optimization to inducing, but the optimization medium on proliferation was cumposited of 3.0 % MS sucrose, 0.75 % agar, 2.0 mg/L 6-BA and 0.l mg/L NAA. The optimization of rooting medium was composited of 2.0 % MS sucrose, 0.50 % agar, 0.5 mg/L 6-BA, 0.1 mg/L NAA and 0.5 g/L activated carbon.
