Abstract
The invention provides a double cherry tissue culture propagation method. An economical efficient double cherry tissue culture propagation technology system is established according to the steps of explant selection, explant sterilization, tissue culture seedling induction, tissue culture seedling proliferation and tissue culture seedling rooting. An improved MS culture medium is adopted, the purposes of improving the double cherry transplantation survival rate, ensuring high propagation coefficient and short period and realizing rapid-propagation seedling culture without external environment influence can be achieved, the excellent characteristics of excellent varieties can be preserved, and the problem in short supply of double cherry is alleviated.
Description
Technical field
The present invention relates to a kind of tissue culture and rapid propagation method, particularly relate to a kind of eightfold cherry tissue culture and rapid propagation method, be applicable to the rapid seedling cultivation of eightfold cherry.
Background technology
Oriental cherry has very high ornamental value, and flower is charming delicate and charming, completely sets splendid as rosy clouds, and therefore whenever oriental cherry blooms the time, the Sacura Festival all can be held in various places; Oriental cherry also has the effect of skin care, shows according to the study, and oriental cherry can pore refining, Sage Extract and lightening skin color, containing abundant natural vitamin A, B, E, is often extracted and makes skin care item; But the life of oriental cherry is very of short duration, an oriental cherry is approximately 7 days from opening into wither, and whole cherry tree from blooming entirely thanking approximately just about 16 days, cannot meet the demand of viewing and admiring of people and the research and development of all kinds of skin-protection product.
Eightfold cherry belongs to rosaceous plant, is deciduous tree, and another name " red cherry " is one of them classification of oriental cherry, leaf egg shape lanceolar, long 8-12 centimetre, ora serrata, alternate; Flower is large, and peony, grows thickly for several, and pendency is open, and petal is multiple and close, the light fragrance of tool, and bennet is long and smooth; Growth characteristics: like sunlight and the environment that cools, the 3-4 month blooms; Primary growth is in Japan, wherein famous with Nara eightfold cherry, and current China various places also start plantation, as garden landscape, view and admire for people; Eightfold cherry is DoubleCherry, and seed is rare, and traditional propagation method seedling is slow, is difficult to a large amount of production; And adopt group culturation rapid propagating technology to be a kind of approach efficiently for the numerous soon of improved seeds, organize according to made oriental cherry and trained successfully, but the tissue culture technology of eightfold cherry kind, current efficiency is desirable not enough.
Summary of the invention
The object of the invention is to provide a kind of eightfold cherry tissue culture and rapid propagation method to overcome above-mentioned deficiency, improve the transplanting survival rate of eightfold cherry, reproduction coefficient is high, cycle is short, be not affected by the external environment, both kept the good characteristic of improved seeds, alleviate again the predicament that supply falls short of demand of eightfold cherry seedling.
For achieving the above object, the present invention carries out in the following way.
A kind of eightfold cherry tissue culture and rapid propagation method, the step of taking root according to explant selection, explant sterilization, plantlet in vitro induction, plantlet in vitro propagation, plantlet in vitro is carried out.
Being chosen as of described explant is chosen sunny day in spring clip in the morning and is newly sent out branch and be in the tender shoots fringe bar of semi-lignified state as explant, draws materials conveniently, easily.
The sterilization of described explant and the way of plantlet in vitro Fiber differentiation are that the explant chosen is soaked 20min with in saturated bleaching powder supernatant, constantly stir in immersion process, then rinse with clear water, dry with filter paper, be placed on superclean bench, first use the alcohol immersion 15s of 75%, then explant is placed in 0.1% mercuric chloride dilution and soaks 8min, then use aseptic water washing 6 times, be then inoculated on inducing culture, inducing culture is additional 1.5 mgL of modified MS medium
