水生植物红宫廷草的快速繁殖研究

红宫廷草(Rotala rotundifolia'Gontin')是一种具有较高观赏和生态价值的水生植物,但是传统的繁殖方式效率较低.为在短时间内获得大量的红宫廷草小苗,该实验选取其茎段为外植体,以 MS(Mu-rashige and Skoog)为基本培养基进行植物组织培养研究其繁殖方法.实验结果表明,MS+0.5 mg/L 6-BA(6-Benzylaminopurine,6-苄氨基嘌呤)为红宫廷草最适的生芽培养基,生芽数为21.1个,叶绿素含量为9.83 mg/L;在MS培养基中添加1 g/L活性炭(Activated carbon,AC)有利于红宫廷草生根,其诱导生根的最适培养基为 MS+1 g/L AC+0.6 mg/L IBA(Indole-butyric acid,吲哚丁酸).红宫廷草组培苗的移栽成活率达100%.该研究建立了红宫廷草的高效离体繁殖体系,为其规模化生产和利用提供了技术保障.
A study on rapid propagation of aquatic plant Rotala rotundifolia'Gontin'by tissue culture
Rotala rotundifolia'Gontin'is a kind of aquatic plants,which has high ornamental and eco-logical value,but the traditional propagation method is difficult to meet the market demand.In order to ob-tain a large number of R.rotundifolia'Gontin'seedlings in a short period of time,the buds were selected as explants,the optimum propagation method of plant tissue culture was studied using MS(Murashige and Skoog)as basic medium.The results showed that MS with 0.5 mg/L 6-BA(6-Benzylaminopurine)was the optimal medium for bud proliferation,with 21.1 buds and 9.83 mg/L chlorophyll content.Adding 1 g/L Activated carbon(AC)in MS medium was beneficial to rooting,and the optimum medium for rooting was MS with 1 g/L AC and 0.6 mg/L IBA(Indole-butyric acid).The transplant survival rate was 100%.In this research,a high frequency establishment of in vitro propagation system on R.rotundifolia'Gontin'will provide a reliable technical support for its large scale production and utilization.
