Abstract
The invention discloses a quick propagation method for oreocharis flavida. The method comprises the following steps: selection and sterilization of an explant; primary culture; multiplication of subculture; rooting culture; and inoculation. By taking tender leaves as the explant, media for the primary culture, the subculture and the rooting culture are set, and the oreocharis flavida is quickly propagated under the condition that the temperature is 24-28 DEG C, the lighting time is 9h/d and the illumination intensity is 1500lx. The method disclosed by the invention is simple and practical to operate, the rooting rate can reach 100%, and plants are robust.
