A kind of method that Moschus dendrobe tissue culture expands breeding seedling
Technical field
The present invention relates to the sides that a kind of tissue cultivating and seedling technology more particularly to a kind of Moschus dendrobe tissue culture expand breeding seedling
Method.
Background technology
The Moschus stem of noble dendrobium (Dendrobium parishii) is orchid family, and the Dendrobium original seed stem of noble dendrobium is mainly distributed on Vietnam, always
The countries such as Laos, Burma are distributed less within Chinese territory;The Moschus stem of noble dendrobium has denseer fragrance, spends purplish red, and petal quality is thicker, stem
Short and sturdy, the villus sense on lip is stronger, and bloom than the spring stem of noble dendrobium more a little later, has higher ornamental value.
The Moschus stem of noble dendrobium to circulate on domestic market there is no artificial mainly by from the national import such as Vietnam, Laos, Burma
Cultivation, maternal less, introduces a collection is rare;It is generally bred by way of division propagation and cuttage, breeding seedling is less, breeding
Rate is low, and growth cycle is longer, and the probability under normal habitat without artificial pollination result is smaller;Since fruit folder is few, fruit powder is thin
It is small, it is not easy the restriction of the factors such as germination and growth in a natural environment so that there is the Moschus stem of noble dendrobium seedling of high ornamental value
Breeding is obstructed.
Invention content
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of Moschus dendrobe tissue cultures to expand breeding seedling
Method.The tissue culture expanding propagation method for culturing seedlings can effectively improve the speed of the breeding of Moschus stem of noble dendrobium seedling and breeding quantity, from mother
This source controls the stability of germplasm, ensures seedling quality, realizes the factorial praluction of Moschus stem of noble dendrobium high quality seed seedling, meets
Production requirement alleviates the present situation of scarcity of resources.
The purpose of the present invention adopts the following technical scheme that realization:A kind of method that Moschus dendrobe tissue culture expands breeding seedling, including,
The step of explant selects:Select the maternal plant of the Moschus stem of noble dendrobium 2-4 of health;It blooms in the spring Moschus stem of noble dendrobium
Period carries out artificial pollination to the stem of noble dendrobium, it is allowed to grow fruit pod, took pains to foster by 3-4 months, when fruit pod maturation, is picked
It puts to refrigerator and is preserved in the environment of 3-7 DEG C 2 weeks;
The step of explant sterilizes:Fruit pod is taken out, fruit pod liquid detergent or washing powder water are impregnated into 15-20min, use hairbrush
Outwash kind shell surface, and rinse 10-15min with tap water;Clean beaker is put it to, moves to transfer room, in an aseptic environment
It is impregnated with medicinal alcohol, being stirred continuously during immersion with tweezers makes its disinfection thorough, aseptic water washing 3-4 times;Hypochlorous acid is used again
Sodium sterilizes shell, aseptic water washing 3-4 times;It is finally sterilized with mercuric chloride, aseptic water washing 4-5 times is put on superclean bench
It is spare in sterile disk;
The step of sowing:The fruit folder scalpel disinfected and tweezers solution are splitted and expose yellow fruit powder, fruit powder is spread to
On 1/2MS culture mediums, lid is sealed after sterilizing bottle cap, goes in culturing room and is cultivated, 30-45 days seeds of culture start to sprout
Hair;
The step of squamous subculture:The amber seed of sprouting is 1500-2000lx, light application time 10-12 in intensity of illumination
It is grown 60 days under conditions of hour/day, Moschus seedling grows to 2-3cm high, level-one mother's bottle is formed, at this time by bottle seedling in gnotobasis
Under go in 1/2MS culture mediums and cultivate 60 days, it is long to referred to as two level mother bottle during 5-6cm;
The step of culture of rootage:The two level mother bottle for growing 60 days is gone into culture of rootage in MS culture mediums in an aseptic environment
90 days;
The step of hardening, rooting culture:Bottle seedling of taking root is cultivated 90 days in culturing room, is taken root good, seedling is sturdy, is moved into
It is placed 15-30 days in outdoor environment, it is allowed to adapt to external environment;It opens bottle cap to place 3-5 days, seedling is poured out into clean culture medium,
Moschus stem of noble dendrobium seedling root 15-20min is impregnated with fungicide, the moisture that dries in the shade is cleaned, is transplanted in matrix and is tamed.
Further, in the step of explant selects, the Moschus stem of noble dendrobium for selecting triennial is best for maternal plant;It is described
Kind shell yellow green other than during fruit pod maturation, subject to intact nothing is split.
Further, in the step of explant sterilizes, the volumetric concentration of the medicinal alcohol is 75%, and soaking time is
30-60s;The volumetric concentration of the sodium hypochlorite is 2%, disinfecting time 1-2min;The mass concentration of the mercuric chloride is
0.1%, disinfecting time 6-8min.
Further, in the step of sowing, the scalpel and tweezers are needed through 286 DEG C high disinfection and are cooled down.
Further, the methyl α-naphthyl acetate of 0.2mg/L, 20g/L are added in the step of sowing, in the 1/2MS culture mediums
The agar powder of sucrose, 4.8g/L, the pH of culture medium are adjusted to 6.0;The condition of culture of the culturing room is as follows:Temperature is 24 DEG C -26
DEG C, intensity of illumination 1500-2000lx, light application time is 10-12 hours/day.
Further, in the step of squamous subculture, in the 1/2MS culture mediums add 0.5mg/L methyl α-naphthyl acetate,
The sucrose of 6 benzyladenine 6-BA, 20g/L of 1.0mg/L, the agar powder of 4.8g/L, the murphy juice of 35g/L, 3g/L activity
Carbon dust, the pH of culture medium are adjusted to 6.0.
Further, in the step of culture of rootage, methyl α-naphthyl acetate, the 2.0mg/L of 0.5mg/L are added in the MS culture mediums
The sucrose of 6 benzyladenine 6-BA, 20g/L, the agar powder of 4.8g/L, the murphy juice of 35g/L, 25g/L bananas juice, 3g/L
Activated carbon powder, the pH of culture medium is adjusted to 6.0.
Further, in the step of hardening, rooting culture, the temperature of the outdoor environment is 22-28 DEG C, humidity is
45%-75%, and need to avoid strong light direct beam.
Further, in the step of hardening, rooting culture, the fungicide is carbendazim solution;By more bacterium during use
Spirit is diluted to 800-1000 times.
Compared with prior art, the beneficial effects of the present invention are:
