A kind of quickly tissue culture method of black fruit lyceum
Technical field
The invention belongs to field of plant tissue culture technique, relate to a kind of tissue culture method, be specifically related to a kind of quickly tissue culture method of black fruit lyceum.
Background technology
Black fruit lyceum (
lycium ruthenicum Murr.) be Solanaceae Lycium, being the raw medicinal plant of a kind of salt, is many quils shrub.Black fruit lyceum taste is sweet, property is put down, not only be rich in the multiple nutritional components such as protein, lycium barbarum polysaccharide, amino acid, vitamin, mineral matter, trace element, also containing abundant black fruit pigment-natural procyanidins, wherein haw matrimony vine is not containing OPC, the procyanidin content of black fruit lyceum exceedes blueberry, is the wild plant that the procyanidin content that finds so far is the highest.Meanwhile, black fruit lyceum has drought resisting, cold-resistant, Salt And Alkali Tolerance, root turion are strong and the plurality of advantages such as resistance to soil depletion, be Saline-alkali Field Control, bank protection, the good seeds that prevent erosion.Therefore, black fruit lyceum no matter in economic product exploitation, or all has market prospects and potentiality to be exploited widely in ecological environment treatment, can become the Important Economic seeds of medicines and health protection, establishment of economic forest and saline land biological control.
At present, black fruit lyceum is mainly wild is main, but wild resource main area natural conditions are severe, and vegetation degeneration is serious, dead even in flakes, causes serious threat to the normal existence of black fruit lyceum, is substantially in Critical Condition.Now, the research overwhelming majority about black fruit lyceum concentrates on its physiological ecological, analysis of effective component, exploitation and administers in desertification and wild provenance domestication, and little about the research report of the tissue culture technology of black fruit lyceum.Great this grade of benevolence tower (2005) utilizes the stem section of band axillalry bud to carry out breaking up to black fruit lyceum and to take root and callus induction adventitious bud proliferation is studied, and only relates to tissue cultures, does not study its fast culture; Number of patent application 201310094393.2 relates to the method for black fruit lyceum high quality seedling Fast-propagation, needs to select black fruit lyceum high quality seed, uses 75% alcohol disinfecting, aseptic water washing 3 ~ 4 times; Again with 0.1% mercuric chloride sterilization, after aseptic water washing 3 ~ 4 times, seed is inoculated in MS medium and cultivates aseptic seedling, cultivate after 1 month, the cane of aseptic seedling is cut, be cut into the stem section of 0.5cm length, access MS+KH
2pO
4proceed in 13.5mg/L+NAA0.1mg/L medium to cultivate, the tissue cultures of its explant is not described in detail.
Summary of the invention
The present invention utilizes tissue culture technique, carry out explant cultivation and obtain black fruit lyceum whole plant, provide a kind of quickly tissue culture method of black fruit lyceum, group training simple flow, not by seasonal climate variable effect, for black fruit lyceum industrialization nursery provides technical support.
First the present invention utilizes plant tissue culture technique to obtain black fruit lyceum plantlet in vitro, then by directly inducing tender stem segments and stem apex axillary bud growth, axillalry bud culture of rootage, cutting stem section or Shoot Tip Culture breeding.
Object of the present invention is achieved through the following technical solutions: a kind of quickly tissue culture method of black fruit lyceum, and it comprises the following steps:
(1) explant sterilization: get the raw then tender stem segments on adult black fruit lyceum branch and stem apex running water 3 ~ 5min, 75% alcohol sterilizing 4 ~ 7s, sterile water wash 2 ~ 3 times, 0.1% mercuric chloride solution sterilizing 13 ~ 17min, sterile water wash 4 ~ 6 times;
(2) Fiber differentiation: be inoculated in inducing culture by the tender stem section after sterilizing and stem apex, cultivates 25 ~ 45 days axillalry buds and is stretched to 3 ~ 5cm in culturing room;
(3) culture of rootage: cut by axillalry bud, is inoculated in root media, within 25 ~ 40 days, obtains the black fruit lyceum plantlet in vitro that length is 6 ~ 10cm, and root length is 5 ~ 10cm;
(4) squamous subculture: with black fruit lyceum plantlet in vitro for parent, be cut to stem section or the stem apex of band 2 ~ 3 bud points, be inoculated in subculture medium and carry out subculture, carry out culture of rootage simultaneously, cultivate in culturing room and within 29 ~ 32 days, obtain being highly the black fruit lyceum whole plant of 6.8 ~ 8.0cm;
(5) acclimatization and transplants: the black fruit lyceum whole plant obtained is closed under natural daylight bottle and take exercise 5 ~ 8 days, hardening of at room temperature uncapping 3 ~ 5 days, take out the medium that single seedling cleans root, with 1000 times of carbendazim solutions to root sterilization 3 ~ 5min, dry and plant in matrix, be transplanted in soil when the new root system that seedling grows reaches 3 ~ 5cm and grows side root.
Medium described in step (2) is MS+0.5mg/L 6-BA+0.1mg/L NAA.
Cultivation indoor conditions described in step (2) is: intensity of illumination 1500LX, light application time 12 ~ 16h/ days, temperature 24 ~ 26 DEG C.
Step (3) and the medium described in step (4) are 1/2MS+0.1mg/L NAA.
Step (3) and the cultivation indoor conditions described in step (4): intensity of illumination 3000LX, light application time 12-16h/ days, temperature 24 ~ 26 DEG C.
Matrix described in step (5) is perlite and peat mixing, and both weight ratios are 1:1.5 ~ 2.5.
Matrix 0.1% disinfecting solution of potassium permanganate described in step (5).
Described to be transplanted in soil after cultivate and see young leaves after 3 ~ 5 weeks and start growth, show that the black fruit lyceum of transplanting survives.
The present invention has following beneficial effect:
(1) in the present invention while black fruit lyceum plantlet in vitro squamous subculture, can culture of rootage be carried out, decrease operating procedure, improve the efficiency of group training, can obtain robust growth, complete plantlet in vitro that genetic character is consistent fast, be a kind of effective way of black fruit Chinese holly quick Qi group training;
(2) in the present invention, step (3) is identical with the medium that step (4) is inoculated, and decreases the process that medium is changed, and simplify group training flow process, easy and simple to handle, the cycle is short, can obtain black fruit lyceum whole plant fast;
(3) the present invention utilizes tissue culture technique, carries out explant cultivation and obtains black fruit lyceum whole plant, by the impact of seasonal climate change, natural calamity, for black fruit lyceum industrialization nursery provides technical support;
(4) the invention solves that black fruit lyceum fertility is low, the problem of scarcity of resources and residue of pesticide; alleviate wild black fruit lyceum resource nervous; protecting wild black fruit lyceum resource, protecting abundant rational exploitation and utilization on basis, the economic worth of black fruit lyceum can be played.
