It turned out reproduction rete of chrysanthemum was raised,the regular,non-plant diseases and insect pests could be offered to the market. Shoot tip were used as explants to study the effects of different sterilization methods, illumination intensity and concentrations of 6-BA and NAA on shoot propagation. Rooting with perlite, vermiculite and river sand instead of agar was studied. In the process of preliminary multiplication, the effect of using 0.1% HgCl_2 in sterilization of explants was better than using saturated bleaching solution. The highest multiplication rate was found under whole illumination.

At the same time ,the cap of filter paper was used for improving transformation ratio. Leaf discs were transferred onto the media MS+ NAA(1mg/L)+6-BA(3mg/L)+Km(30mg/L)for regeneration resistant selction. Shoots from selection medium were cultured on medium MS +NAA(1mg/L)+6-BA(3mg/L)+Km(50mg/L) for selection again,and then on the media 1/2MS+NAA(0.2mg/L)+IBA(0.2mg/L)+Km(25mg/L)for rooting selectin.

Segments produced clusters of somatic embryos from embryogenic calli or directly from root apical meristems , and that also can convert into bud directly in the different tissue culture conditions. Modified media B5 with 1.0 mg.L-1 2,4 - D and 3.0mg.L~1 6-BA is suit to induce calli, and 0.5 mg.L-1 NAA is fit for somatic embryos inducement from calli. 6-BA encreased direct somatic embryogenesis on root tip distinctly,but NAA is retard it. NAA also prolong the time of root-tip convert into bud directly.

在改良B_5(微量元素为原来的1/3)中加入1.0mg.L~(-1)2,4—D和3.0mg.L~(-1)6-BA对离体根尖的愈伤组织诱导较为合适,0.5mg.L~(-1)NAA有利于从愈伤组织上产生体细胞胚;6-BA明显促进离体根尖直接产生类原球茎,而NAA则有阻碍作用;同时NAA的存在也使离体根尖直接成芽的时间延长。
