柠檬马鞭草快速繁殖技术研究

选择柠檬马鞭草带腋芽的幼嫩茎段为外植体进行快速繁殖。结果表明，腋芽诱导的最适培养基是MS基本培养基附加6-BA0.5～1.0mg／L和IBA0．1～0．3mg／L．外植体腋芽能正常萌发生长，并迅速进入增殖状态，20d转接1次，增殖倍数存3倍以上，最适生根培养基是1／2MS基本培养基附加IBA0．5mg／L，诱导生根率达99％。将生根苗移入苗盆。30d的成活率在85％以上。

Tissue Culture Technique for Rapid Propagation of Lippia triphylla

Young Lippia triphylla stems with buds were employed as the explants to conduct the rapid propagation of Lippia triphylla,which showed that the optimal medium for axillary bud induction was MS+0.2~0.5 mg/L 6-BA+0.1~0.3 mg/L,and the buds of the explants could normally germinate and quickly develop into their proliferating stage on the medium;and then the seedlings from the explants were transferred every twenty days and thus the propagation multiplicity surpassed three.The optimal medium for root induction was 1/2 MS+0.5 mg/L BA and its root-inducing rate reached as high as 99%.The rooted seedlings were transplanted to the pots and their survival rate reached more than 85%.
