驱蚊香草组织培养与快速繁殖

以驱蚊香草不同部位为外植体，进行离体快繁试验，结果表明：外植体以叶片和顶芽容易诱导产生愈伤组织，最高诱导率达90％；诱导培养基以MS＋6-BA1．0—2．0mg·L^-1＋NAA0．2mg·L^-1效果较好，平均芽诱导分化率达85．6％一86．7％；增殖培养基以MS＋6-BA1．5mg·L^-1＋NAA0．1mg·L^-1效果最好，丛生芽增殖量多，繁殖系数达6倍以上；用MS＋6-BA1．5mg·L^-1＋NAA0．1mg·L^-1培养基进行壮苗培养，诱导生根培养基以1／2MS＋NAA0．1—0．3mg·L^-1，生根率达到100％；假植20d后，移栽成活率达100％，本结果为驱蚊香草离体无性繁殖系的建立提供参考．

Tissue culture & fast regeneration of cymbopogon citrates

This experiment utilizes various regeneration, whose result demonstrates that callus by inducement, and the maximum rate MS＋6-BA1.0-2.0mg·L^-1 ＋NAA0.2 differentiation rate reaching 85.6 -86.7% ;the proliferation culture medium of MS ＋ 6 - BA 1.5 mg ·L^-1 ＋ NAA0.1 mg ·L^-1 highlights the best result, with the largest number of clustering buds, the reproduction quotiety is 6 times. I use culture medium MS ＋6 - BA 1.5mg·L^-1 ＋ NAA0.1 mg ·L^-1 to enable strong seedlings, while using 1/2MS ＋ NAA0. 1 -0.3rag ·L^-1 as radication inducement culture medium, with 100% of radication rate; the survival ratio of the transplanted seedlings reaches 100% after 20 days of temporary planting. This experiment result provides references for the formation of cymbopogon citrates explanting vegetative propagation.
