Description
Technical field
The present invention relates to a kind of protruding canine teeth stem of noble dendrobium method for tissue culture.
Background technology
The protruding canine teeth stem of noble dendrobium, that is, hide the southern stem of noble dendrobium (scientific name：Dendrobium monticola P.F.Hunt et Summerh.) it is raw
In on the mountain valley rock of height above sea level 1750-2200 rice.Guangxi China southwest and southern Tibet are distributed in, the India northwestward is through Nepal
It is also distributed to Sillim and Thailand.It has abundant active polysaccharide, has medical value.It generally has raceme normal
1-4, basidixed or sends from the stem top of raw tool leaf then, it is near upright or it is curved hang down, it is long 2.5-5 centimetres, have several little Hua；The flowers are in blossom
Exhibition, white；The long and narrow circle of petal, tip is tapering, contracting of slightly being hung in the middle part of the nearly ellipse of lip, and more than middle part 3 split, base portion tool shortly clawed,
Great sight, there is higher horticultural importance.
The protruding canine teeth stem of noble dendrobium be it is a kind of like shady and cool herbaceos perennial, like it is warm, moist, with 1000 millimeters of annual rainfall
Above, the environment of half cloudy half light, 1 monthly mean temperature grows in the subtropical zone remote, thickly forested mountains higher than 8 DEG C to be preferred, suitable growth temperature
For 15 to 28 degree, suitable growth air humidity is more than 60%, requires not very strict to clay fertilizer, wild more in loose and thick tree
Grown on skin or trunk, some is also grown in crack of stone.Belong to aerial root system, major requirement root permeability is good, the matrix of use
Preferably ventilated drainage, under suitable temperature humidity, the speed of growth is fast, and survival ability is very strong.Annual the end of spring and the beginning of summer,
Inflorescence is extracted out on biennial stem top section, and Post flowering grows sprouting from stem foot and develops into stem, and autumn and winter enters rest period.Mesh
Before, the artificial culture of the protruding canine teeth stem of noble dendrobium includes division propagation, cutting propagation, proliferation, still, above-mentioned modes of reproduction reproductive efficiency
It is low, it is impossible to meet the market demand, therefore, it is necessary to the protruding canine teeth stem of noble dendrobium is quickly bred using plant tissue culture technique.
The content of the invention
It is an object of the invention to provide a kind of protruding canine teeth stem of noble dendrobium method for tissue culture.
To realize the purpose of the present invention, the present invention uses following technical scheme：A kind of protruding canine teeth stem of noble dendrobium method for tissue culture, bag
Protruding canine teeth stem of noble dendrobium seed culture is included to sprout into ball stem, strong seedling culture, root induction, four steps of hardening, wherein the protruding canine teeth stone
The culture medium difference that dry measure used in former times seed culture uses in sprouting into ball stem, strong sprout and root induction is as follows：
