The invention provides a Dangshan pear genetic transformation method. The Dangshan pear genetic transformation method comprises the following steps: (1) constructing a genetic transformation receptor; (2) culturing agrobacterium tumefaciens and preparing infection solution; (3) carrying out infection and coculture; (4) carrying out sterilization culture and screening culture; and (5) carrying out resistant callus GUS (glucuronidase) staining identification. The Dangshan pear genetic transformation method has the advantages that Dangshan pear callus is taken as the receptor, NptII is taken as a marker gene, GUS gene is taken as a reporter gene, Dangshan pear genetic transformation is carried out by adopting an agrobacterium EHA105 mediated process for obtaining positive resistant callus, and then redifferentiation is carried out by virtue of the positive resistant callus for obtaining test-tube plantlets; meanwhile, a method for carrying out genetic transformation by firstly inducing resistant callus by virtue of fresh treetop, taken as an explant, grown the same year of Dangshan pear is firstly established, content of phenolic substances in fresh treetops of the Dangshan pear in spring is low, less germs are carried, both inoculation browning rate and contamination rate are low, materials are available, callus induction ratio is high, and demand of genetic transformation can be met.

The invention discloses a culture medium box set for promoting in-vitro rapid propagation of zingiber mioga. The culture medium box set is characterized in that an MS culture medium is used as a basic culture medium, and is added with 1.0 to 3.0mg / L of BA (butyl acrylate), 0.01 to 0.02mg / L of TDZ (thidiazuron), 0.04 to 0.06mg / L of NAA (naphthalene acetic acid), 25 to 35g / L of sugarcane and 6.5 to 7.5g / L of agar, so as to obtain the propagation culture medium. The invention also discloses a method using the culture medium box set to promote the in-vitro rapid propagation of the zingiber mioga. The method has the advantages that under the optimizing conditions, after the zingiber mioga is cultured by the method,; 10 to 15 propagation times can be reached; after 30 days, the rooting rate is 100%; the transplanting survival rate is 100%.

The invention discloses an induction culture method of a rhizoma bletillae embryoid. The induction culture method comprises the following steps: taking a rhizoma bletillae seed as an explant, culturing a protocorm without differentiating cotyledons firstly, then carrying out culturing on the protocorm without differentiating cotyledons to obtain embryogenic tissue cells with strong division rate and green color, and carrying out induction culture on the embryogenic tissue cells to obtain the rhizoma bletillae embryoid finally. The induction culture method provides a new way for mass cultivation and rapid reproduction of good quality seedlings of rhizoma bletillae, and the problem that the rhizoma bletillae plant resources and seedling resources are short at present can be effectively solved.

The invention relates to a tissue culture method for rapid propagation of alum root "tiramisu", and relates to the technical field of plant tissue culture. The present invention takes alum root petiole as explant, involves steps such as aseptic system establishment, callus induction, callus induction to form adventitious buds, adventitious bud proliferation, rooting induction, seedling hardening and transplanting, etc., and establishes a complete set of Tissue culture rapid propagation method of alum root "Tiramisu". This culture method has the advantages of fast propagation speed, high multiplication rate and low pollution rate, and can quickly produce high-quality seedlings in the production process. Commercial development has important practical application value.
