The method comprises the following specific steps: (1) preparation of a culture medium including a basic culture medium and components of the culture medium at all stages of tissue culture; (2) selection and disinfection of explants; (3) induction and multiplication of adventitious buds; (4) rooting culture; and (5) transplantation. The method disclosed by the invention has the beneficial effects that the adventitious bud induction and the multiplication culture are carried out on the water nymph by utilizing a plant-tissue culture technology, so that a great quantity of high-quality strong seedlings with consistent genetic characters can be obtained in short time, the defect of slowness of a conventional multiplication method is overcome, and simultaneously, the method has the positive significance for both large-scale production and germplasm resource conservation.
Description
Technical field
The present invention relates to plant tissue culture technique, be specifically related to a kind of method of water lily tissue cultures.
Background technology
Water lily (Nymphaea tetragona Georgi) is the perennial aquatic herbaceous plant of Nymphaeceae Nymphaea, and floral leaf is all beautiful, and pattern enriches, and flowering stage is long, and ornamental value is high; The root of water lily can absorb the noxious material such as lead, mercury, phenol in water, is rare water body purification plant; In addition water lily also has certain medical value.But water lily many dependences division propagation and seed propagation, reproduction coefficient is low, the cycle is long, is difficult to the needs meeting market.Therefore; plant tissue culture technique is utilized to carry out the Fast-propagation of water lily; a large amount of seedling consistent with maternal plant genetic character can obtained more in a short time; this for preservation fine germplasm resources, breed famous-brand and high-quality water lily kind and have great importance, also have practical using value for realizing its large-scale production with the demand meeting domestic and international market simultaneously.But, before this also not about the report of water lily Study on tissue culture, more there is no successful example.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and a kind of method of water lily tissue cultures is provided.
For achieving the above object, the technical solution used in the present invention is: the method for this water lily tissue cultures mainly comprises the steps:
1), the preparation of medium:
(1) minimal medium: adopt double layer culture base, its upper strata is sterile distilled water; Lower floor is MS solid culture medium, wherein sucrose 20 ~ 30g/L, agar 5 ~ 9g/L, pH=5.8;
(2) inducing culture solid layer: MS+TDZ 1.0 ~ 3.0mg/L+NAA 0.05 ~ 0.5mg/L+ active carbon 0.2 ~ 0.5mg/L; (3) proliferated culture medium solid layer: MS+6-BA 2.0 ~ 4.0mg/L+NAA 0.1 ~ 0.5mg/L;
(4) root media solid layer: MS+NAA 0.05 ~ 0.2mg/L+IBA 0.05 ~ 0.2mg/L;
2) the choosing and sterilizing of explant: repair smooth by the terminal bud on water lily rhizome and lateral bud periphery, cleans and for subsequent use after sterilizing;
3) induction of indefinite bud and propagation: by step 2) disinfect after sprout be aseptically inoculated in the solid layer of inducing culture, directly can induce indefinite bud after 1 ~ 2 month, indefinite bud is transferred on proliferated culture medium and can must breed further;
4) culture of rootage: by step 3) propagation bud clump is transferred on root media after being aseptically divided into individual plant, and cultivate and can take root after 15 ~ 25 days;
5) transplant: by step 4) the water lily plant that takes root takes out and cleans, then transplanting and cultivate to muddy water groove from medium.
Further, the present invention is in described step 1) in, the component that described medium comprises minimal medium and each stage medium of group training is specially:
(1) minimal medium: adopt double layer culture base, its upper strata is sterile distilled water; Lower floor is MS solid culture medium, wherein sucrose 20 ~ 30g/L, agar 5 ~ 9g/L, pH=5.8;
(2) inducing culture solid layer: MS+TDZ 2.0mg/L+NAA 0.5mg/L+ active carbon 0.2mg/L;
(3) proliferated culture medium solid layer: MS+6-BA 3.0mg/L+NAA 0.2mg/L;
(4) strong seedling culture base solid layer: MS+NAA 0.1mg/L+IBA 0.1mg/L.
Further, the present invention is in described step 2) in, described disinfecting takes after water lily rhizome removes blade terminal bud, lateral bud to cut together with part rhizome tissue, with sharp blade the blade of sprout periphery and batting excised and repair smooth rear saturated washing powder solution soak in 20 ~ 60min, and then it is clean with tap water, then the alcohol, the effective chlorine density that are 70% in volume ratio be successively 1% liquor natrii hypochloritis and 0.1% mercuric chloride in soak 0.5 ~ 1min, 4 ~ 8min and 4 ~ 6min respectively, finally use aseptic water washing 3 ~ 5 times.
Further, the present invention is in described step 3) in, described in disinfect after sprout be directly inoculated in evoking adventive bud eruption in the solid layer of inducing culture, be transferred to after the indefinite bud induced is cut in proliferated culture medium carry out propagation expand numerous.
Further, the present invention is in described step 5) in, described transplanting is taken out from medium and clean root remaining medium by the water lily plant after taking root, and then transplants and cultivate to the cultivating groove that muddy water is housed.
Beneficial effect of the present invention is: utilize plant tissue culture technique to carry out cultured in vitro to water lily; the high-quality strong sprout that a large amount of genetic character is consistent can be obtained within a short period of time; overcome the shortcoming that Sterile culture method is slow, all there is positive effect to its large-scale production and Germ-plasma resources protection.
