Embodiment 2

[0040] The basic medium MS and MW medium used in this method are the same as in Example 1.

[0041] The mature seeds of Fusui Dongdong Golden Camellia collected in October 2013 were used as explants, and the seed coat was peeled off. Before inoculation, the surface was sterilized with 75% alcohol for 40 seconds, and then sterilized with 8% NaClO solution for 25 minutes. , and finally rinse with sterile distilled water on the ultra-clean bench until it is clean.

[0042] Cut the sterilized seeds in the middle, and put the part with the embryo into the primary induction medium. The first-generation induction basic medium is based on MS medium, which also includes 6-BA 0.5mg / L, NAA 0.2mg / L, sucrose 30g / L and agar 6g / L, and the pH is adjusted to 5.8 to induce sterile bud.

[0043] The aseptic buds induced by the first generation were cut into terminal buds and stems with buds and inoculated on the subculture medium respectively. The subculture medium used MS as the basic me...

Embodiment 3

[0049] The basic medium MS and MW medium used in this method are the same as in Example 1.

[0050] The hybrid golden camellia seeds collected in October 2013 were used as explants, and the seed coat was peeled off. Before inoculation, the surface was sterilized with alcohol with a volume concentration of 75% for 60 seconds, and then sterilized with a NaClO solution with a volume concentration of 5% for 30 minutes. Rinse with sterile distilled water until clean.

[0051] Cut the sterilized seeds in the middle, and put the part with the embryo into the primary induction medium. The first-generation induction basic medium is based on MS medium, which also includes 6-BA 0.2mg / L, NAA 0.5mg / L, sucrose 30g / L and agar 6g / L, and the pH is adjusted to 5.8 to induce sterile bud.

[0052] The aseptic buds induced by the first generation were cut into terminal buds and stems with buds and inoculated on the subculture medium respectively. The subculture medium used MS as the basic m...

Abstract

The invention provides a camellia chrysantha tissue culture propagation method. The camellia chrysantha tissue culture propagation method comprises the steps of obtaining aseptic seedlings, propagating the aseptic seedlings, culturing strong multiple shoots, expanding propagation and carrying out rooting culture, wherein camellia chrysantha embryos are selected as explants and then inoculated to a primary culture medium to obtain the aseptic seedlings of the camellia chrysantha; next, the aseptic seedlings are inoculated to a subculture multiplication culture medium and a strong shoot culture medium; the seedling propagation and strengthening processes are repeated and circulated until a large quantity of strong aseptic seedlings are obtained; finally, the aseptic seedlings are transplanted to a rooting culture medium for rooting culture. The camellia chrysantha tissue culture propagation method has the advantages that the vitrification problem of the aseptic seedlings in the camellia chrysantha tissue culture process is overcome, multiple subculture of materials can be realized, large-scale propagation is realized, the seedling growing period of the camellia chrysantha is shortened, the seedling growing materials are saved, the rooting rate is 95%-98%, and the transplanting survival rate is more than 90%; as a result, the camellia chrysantha tissue culture propagation method has excellent economic benefit, social benefit and ecologic benefit.

Description

technical field [0001] The invention belongs to the technical field of plant propagation and relates to tissue culture seedling raising technology, in particular to a method for tissue culture propagation of camellia japonica. Background technique [0002] In 1960, Chinese scientists first discovered a golden camellia in Nanning, Guangxi, which was named Camellia japonica. The discovery of camellia camellia has caused a sensation in the global horticultural circles and the press, and has been highly valued by horticulturalists at home and abroad. It is considered to be the best raw material for cultivating golden camellia varieties. Camellia japonica is an ancient plant, extremely rare. It is as famous as precious "living fossils of plants" such as silver fir, spinosa, and Davidia involucrata. Clan Queen". In addition, golden camellia contains special genetic genes for color and luster, which has important scientific research value. According to scientific identification,...
