Abstract
The invention provides a method of tissue culture propagation for rhizome polygonati, comprising the steps of introducing and sterilizing, tissue inducing, subculturing, and carrying out differentiation culture, strong seedling culture and rooting culture. The beneficial effects of the method are that seedlings can be produced in large amount by the tissue culture, and only seven months are needed from tuber to rooted seedling by culturing; thus production time and cost of seedlings are greatly decreased and propagation speed is increased.
Description
Technical field
The present invention relates to the tissue culture propagation method in a kind of traditional Chinese medicine culture technique field, particularly a kind of sealwort.
Background technology
Sealwort is a Liliaceae Polygonatum herbaceos perennial, and sealwort is arranged, Yunnan sealwort and David's-harp etc., and its dry rhizome is used as medicine.According to the classical record of traditional medicine, sealwort belongs to rare Chinese medicine, have wide in beneficial gas, enriching kidney essence, nourishing Yin and moistening lung, the effect of the tonifying spleen of promoting the production of body fluid.Cure mainly illnesss such as dryness of the lung dry cough, body void are weak, palpitation, prolonged illness body fluid deficiency dry, diabetes, hypertension.To treatment angiocardiopathy, tuberculosis, chronic hepatitis and at antibiotic, detoxifcation, antifatigue, anti-ageing, hypoglycemic, reducing blood lipid, aspect such as antitumor better effect is arranged all; Both can be used as medicine; Can be used as health food again; Since ancient times, people sealwort as the good merchantable brand of promoting longevity, thereby being in great demand to sealwort.
For a long time, the sealwort crude drug source is main with wild collection mainly, and the culture technique of sealwort does not cause more concern.Along with market to the increase of medicinal material sealwort demand and the rapid minimizing of wild resource, gather wild sealwort and not only can not meet the need of market, destroyed ecotope and sealwort wild resource on the contrary.People begin man culture technique, the high-yield culture technique etc. of planting of the wild change of sealwort are put into practice gradually thus.The propagation technique of sealwort is mainly seminal propagation and rhizome breeding dual mode at present.
Collect because the sealwort seed is difficult, percentage of seedgermination is low, and seminal propagation, and seedling raise period is long, has increased the cultivation cost of sealwort greatly, is unfavorable for the artificial establishing in large scale of sealwort.So in current artificial cultivation, breed the breeding of main dependence rhizome, but this method reproduction coefficient is low, kind rhizome consumption is big, both uneconomical, has limited the yield potentiality of sealwort again, inconvenience is planted to manage and is promoted, thereby the expansion cultivated area is suppressed.
Summary of the invention
The object of the present invention is to provide a kind of sealwort tissue culture propagation method, improve the expanding propagation speed of sealwort, realize the standardization and the large-scale development of sealwort cultivation.For realizing this purpose; The inventor is through overtesting; The various tissue culture prescriptions and the cultural method of breeding sealwort have successfully been studied; To tissue culture prescription and production technology, and the special habit of growth of sealwort carried out big quantity research and repetition test, obtained the culture medium prescription and the cultural method of original creation.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is the sealwort tissue culture propagation method, comprise introduce a fine variety that sterilization, tissue are induced, successive transfer culture, differentiation culture, strong seedling culture and culture of rootage, concrete grammar is following.
introduces a fine variety sterilization: the sealwort rhizome of getting the band bud; Be cut into the segment of 0.5-1.0cm by knife; Put into the liquid detergent aqueous solution and soaked 5 minutes, rinse well with running water then; Use 75% ethanol scrub surfaces again, rinse well with running water again; Get in the superclean bench then and operate, put into for 75% ethanol half a minute, the sterilization deionized water is rinsed and is washed twice; Put into 2.5% clorox again 5 minutes, the sterilization deionized water is rinsed and is washed 2 times; And put into 5% clorox 5 minutes, the sterilization deionized water is rinsed continuously and is washed 3-5 time, cuts wound necrosis part with cutter then.
tissue is induced: the rhizome after will disinfecting is seeded on the inducing culture; Every bottle graft kind 1-3 piece; Carrying out callus induction cultivates; The rhizome incision had a small amount of callus to begin to sprout in 28-32 days; The callus of faint yellow densification occurred in 50-60 days, inductivity reaches 50%.
successive transfer culture: will induce the good faint yellow granular callus of growth conditions of generation to be inoculated in the subculture medium; Every bottle graft kind 2-3 piece; Carry out successive transfer culture; Can be observed in 28-32 days has new callus to produce again in the subculture medium; 43-47 days, can be observed callus and increase 1 times than original.
differentiation culture: the good faint yellow graininess callus of growth conditions that shoot proliferation is produced is transferred on the differential medium; Every bottle graft kind 2-3 piece carries out differentiation culture, can be observed callus and begins Growth and Differentiation in 9-11 days; It is green that color turns; Can be observed the pistac indefinite bud in 19-21 days, began to produce the bud of growing thickly, bud ratio 66% in 45-50 days; 5 buds of average every callus differentiation, the average length of bud is 12mm.
strong seedling culture: the bud of growing thickly of differentiation culture is transferred to carries out strong seedling culture in the strong seedling culture base, can be observed the seedling of growing thickly that the bud of growing thickly has developed into 2.0-4.0cm in 30 days.
culture of rootage: the seedling of growing thickly of strong seedling culture is transferred to root induction on the root media; Can be observed shoot root in 15 days begins to sprout; Can be observed 86% seedling in 30 days all takes root; Coring average length 4cm, every young plant are on average taken root 6; But bottle outlet refining seedling is transplanted then.
In the above-mentioned sealwort tissue culture propagation method, the condition of culture in each development growth stage of being mentioned is: the artificial climate incubator, and the periodicity of illumination beginning and ending time is 8:00-20:00; Cultivation temperature day 25 ℃ of temperature; Night, temperature was 18 ℃, and cultivating humidity is 60%, and intensity of illumination is 2000-2400lx.
In the above-mentioned sealwort tissue culture propagation method, the minimal medium in each development growth stage of being mentioned is: MS+30g/L sucrose+5g/L agar powder, pH value are 5.8-6.0.
In the above-mentioned sealwort tissue culture propagation method, the prescription of each development growth stage medium of being mentioned is.
differential medium: MS+6-BA3.0mg/L+IAA1.0mg/L.
The invention has the beneficial effects as follows: stem tuber repeated multiple times sterilizing and washing in short-term is of reduced contamination, reduced the damage of bactericidal agent to explant; Through tissue culture, can produce seedling in a large number, become to take root seedling from stem tuber to cultivating, only need 7 months, shortened seedling production time and cost greatly, improved reproductive speed.
