Abstract

The invention discloses a culture medium for culturing hoya tissue and a culture method. The culture medium comprises an explant induction culture medium, a proliferation subculture culture medium, a bud differentiation culture medium, a rooting culture medium and a rooting soak solution, wherein the explant induction culture medium is composed of agar, minimal culture medium MS, kinetin KT, 6-benzyladenine 6-BA and naphthylacetic acid NAA; the proliferation subculture culture medium is composed of the agar, the minimal culture medium MS, the 6-benzyladenine 6-BA, the naphthylacetic acid NAA, gibberellin GA and cerous nitrate; the bud differentiation culture medium is composed of the agar, the minimal culture medium MS, the kinetin KT, the naphthylacetic acid NAA, the gibberellin GA, lanthanum nitrate La(NO3)3 and the cerous nitrate Ce(NO3)3; and the rooting culture medium is composed of the agar, minimal culture medium White, the gibberellin GA and lanthanum chloride LaCl3. By utilizing the culture medium, the quality of tissue culture seedling of hoya is greatly improved, and propagation of the tissue culture seedling of the hoya is effectively improved so that industrial production of the hoya is further promoted.

Description

technical field [0001] The invention belongs to the technical field of plant tissue culture, and in particular relates to a culture medium and a culture method for plant tissue culture. Background technique [0002] With the development of plant tissue culture technology, it has become a trend to carry out commercial batch cultivation and production of ball orchids through tissue culture technology. Traditional ball orchids are almost always cultivated by cutting propagation method, but this propagation method takes root slowly, and after survival and transplantation, the seedlings are not vigorous and the growth is relatively slow. Therefore, it is an important technical means to solve the above breeding problems by tissue culture technology to propagate the bulbous orchid. At present, the tissue culture technology of ball blue has been reported in the laboratory stage experiment, and there is a precedent of establishing a sterile line and being able to multiply. A means ...
