Summary of the invention
The purpose of this invention is to provide and a kind ofly carry out notopterygium root quality saving and fast seedling-breeding method by tissue culture.
Technical scheme of the present invention is:
A kind of angelica tissue culture breeding method, it is characterized in that: the radical bud that sprouts with notopterygium root is an explant, after sterile-processed, inoculation is induced and is formed callus, breed, lure bud to cultivate and culture of rootage through callus again, grow up to complete plant seedling, complete seedling is transplanted in the seedling medium, grows up to normal notopterygium root plant.
Described angelica tissue culture breeding method comprises the following steps:
The selection of A, explant and disinfecting: the radical bud that sprouts with notopterygium root is an explant, with flowing water flushing 3~5 minutes, be 75% alcohol-pickled sterilization 45~60 seconds with concentration again, with aseptic deionized water flushing 2~3 times, it is 0.1%~0.2% mercuric chloride that explant after will washing again places concentration, soak sterilization 10~14 minutes, aseptic deionized water flushing 2~3 times, standby;
B, explant inoculation: will be cut into 0.1~0.3cm through explant standby in the steps A
3Fritter, be seeded on the callus inducing medium, incubation time is 30~35 days, expands the formation callus in the radical bud incision;
C, callus propagation: the callus that obtains among the step B is inoculated on the callus proliferated culture medium, and callus was bred 25~35 days, grew the callus of yellow, densification;
The bud of D, callus is induced: the callus that obtains among the step C is inoculated into lures on the bud medium, cultivated 35~45 days, the notopterygium root seedling occurs growing thickly;
E, culture of rootage: the notopterygium root seedling plant division of growing thickly with obtaining among the step D, change in the root media, to cultivate 20~30 days, the seedling base portion the short root of white occurs and grows complete root system;
F, plantlet of transplant: before the transplanting, to containing the seedling medium sterilization of vermiculite, peat, to seedling medium, need not hardening can directly survive, and grows up to normal notopterygium root plant with the complete little seedling direct transplantation that obtains in the step e.
Described explant is disinfected and is adopted 75% alcohol-pickled sterilization 45~60 seconds and 0.1%~0.2% mercuric chloride to soak dual twice sterilization method of 10~14 minutes of sterilization.
