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. MS media with 6-BA from 0.2 mg·L~(-1) to 5 mg·L~(-1) and NAA from 0.05 mg·L~(-1) to 2 mg·L~(-1) were tested and as a result, the highest differentiation rate and the multiplication rate was reached with 0.2 mg·L~(-1) 6-BA, 0.05 mg·L~(-1) NAA.
本实验以菊花的茎尖为外植体,研究了不同灭菌方法,光照强度,全光照、半光照和弱光处理以及不同6-BA和NAA浓度及配比对于试管苗增殖的影响,并研究了珍珠岩、蛭石和河砂等琼脂替代物对于菊花生根的影响,结果表明:在初代培养物建立的过程中采用0.1%升汞进行表面灭菌的效果好于饱和漂白粉的灭菌效果;在全光照条件下外植体的增殖倍数最高;在试管苗增殖培养的过程中,以MS为基本培养基,并在培养基中添加0.2~5mg·L~(-1)6-BA和0.05~2mg·L~(-1)NAA,其中0.2mg·L~(-1)6-BA和0.05mg·L~(-1)NAA最适于外植体的分化和增殖,其分化率为100%,增殖倍数为12。
