The traditional propagation methods for A. mamillata by seeds or cutting provided low proliferation rate. This study is to optimize the propagation technique of A. mamillata by tissue culture and set up an industrial production system to provide plenty of A. mamillata seedlings for the human demand. The optimal initiation medium for A. mamillata is MS +2.0 mg/L BA +0.1 mg/L NAA +30 g/L sugar, providing76.4% initiation rate. The optimal shoot proliferation medium for A. mamillata is MS+1.0 mg/L BA+0.1 mg/L NAA+30 g/L sugar, providing 4.56 fold proliferation rate and3.10 cm shoot in height. The optimal shoot elongation medium for A. mamillata is MS+0.5 mg/L BA+0.1 mg/L NAA+30 g/L sugar, providing 2.77 fold proliferation rate and 4.27 cm shoot in height. The optimal rooting medium for A. mamillata is 1/2MS+0.1 mg/L IBA +15 g/L sugar, providing 99.7% rooting rate, 4.0 roots per individual,7.53 cm root in length and 3.94 cm shoot in height. This provides a reliable mass propagation method for A. mamillata.展开更多
