Abstract:
In order to protect the wild resource of Psammosilene tunicoides effectively, tender stems of Ptunicoides were used as explants to study the in vitro rapid propagation technique of Ptunicoides. The results showed that the method of sterilization was that tender stems were rinsed with water, then disinfect with 75% alcohol for 15s and 01% mercuric for 10min. The contamination rate was 361%. Differentiation culture medium was MS + 20mg/L 6BA + 005mg/L TDZ + 005mg/L NAA, the average quantity of differentiation bud was 349, proliferation culture medium was MS + 03mg/L 6BA + 005mg/L TDZ + 001mg/L NAA, the proliferation multiple was 429, Rooting culture medium was 1/2MS + 03mg/L IBA + 01mg/L NAA + 03g/L activated carbon, the rooting rate was 917%, the tissue culture seedlings were transplanted into the matrix (red soil∶humus∶perlite=1∶1∶1), the survival rate was 945%. The technology of tissue culture is hopeful to solve the problem of wild resource shortage and insufficient supply of raw materials in the production.
