玫瑰天竺葵组培快繁技术体系的建立

以玫瑰天竺葵茎段为外植体材料，研究其组培快繁技术体系。结果表明：初代诱导培养基以MS+BA1.0mg/L+NAA0.1mg/L为宜；继代培养基以MS+BA0.5mg/L+NAA0.05mg/L为宜，芽增殖倍数为5.8；生根培养基以1/2MS+IBAA0.6mg/L为宜，生根率达97.5%以上，平均生根数13.8条；移栽基质以泥炭土∶珍珠岩=3∶1为宜，成活率达98.3%。

Establishment of Tissue Culture and Rapid Propagation System of Pelargonium roseu

The tissue culture and rapid propagation system of Pelargonium roseu is studied using stems as explants in this paper. The results showed that the suitable shoot-inducing medium was MS+BA1.0mg/L+NAA0.1mg/L,with inducement rate up to 96.7%.The suitable shoots multiplication culture medium was MS+BA0.5mg/L+NAA0.05mg/L,with multiplication coefficient of 5.8.The suitable rooting culture medium was 1/2MS+IBAA0.6mg/L,with rooting rate up to 97.5%,in which average number of roots was 13.8. The suitable trans?plant medium was peat soil∶perlite (V/V)=3∶1,with survival rate up to 98.3%.
