火炬姜离体快繁技术研究

 试验表明：火炬姜组培快繁以Ms+6-BA 2.0mg/L+NAA 0.1 mg/L+CW 10%作为增殖培养基可以获得理想的效果，增殖倍数可达4.3倍；以双芽为外植体在该培养基上经30 d培养可增殖5.4倍；在不含任何激素的1/2 Ms+0.15%活性炭培养基上即可形成较发达的根系，生根率达100%；试管苗移栽对基质要求不严，移栽到疏松透气、富含有机质的表土中，成活率高达100%，而且植株生长良好。

Studies on Rapid in Vitro Propagation of Phaeomeria magnifica

The research result of the in vitro propagation of the Phaeomeria magnifica is presented in this paper.The results showed that:Using MS+6-BA 2.0 mg/L+NAA 0.1 mg/L+CW 10% as proliferation medium,an optimal proliferation rate was obtained,the proliferation rate could reach 4.3 times;Using double shoots as explants,after 30 days of culture in this medium,it could amplify 5.4 times.The root formation of Phaeomeria magnifica tissue culture shoots had a low demand for exotic hormones,even in a medium of no hormones it could still form a good root system,the rooting rate could reach 100%.The transplantation of Phaeomeria magnifica tissue culture shoots was simple and feasible.There was no strict demand for matrix,when the plantlets were transplanted to superficial soil,the survival rate could reach 100%,and the plants grew well.
