The invention discloses a propagation method for coral grass seedling tissue culture, and aims to provide a propagation method for coral grass seedling tissue culture with high propagation speed and low cost. The propagation method comprises the following steps: (a) a step of induction and differentiation of buds; (b) a propagation culture step of sterile seedlings; and (c) an acclimation and transplantation step of the sterile seedlings. The propagation method adopts an MS culture medium of 0.5 to 1.5 mg / L of 6BA and 0.05 to 0.15 mg / L of 2,4-D to effectively promote quick differentiation of coral grass leaves to form adventitious buds, and adopts the propagation culture in an MS culture medium of 0.3 to 1 mg / L of 6BA and 3 percent of sugar to propagate the adventitious buds exuberantly; and finally, the propagation seedlings are placed in an MS culture medium of 0.8 to 1.5 mg / L 3IBA and 3 percent of sugar, and the periphery of the propagation seedlings can quickly take roots. The propagation method can be widely applied to the field of coral grass seedling tissue culture.

The invention relates to a tissue culture and rapid propagation method of micro tubers of rhizoma bletillae. The method comprises the following steps: (1) selecting rhizoma bletillae fruits; (2) performing aseptic seeding; (3) culturing to enable seed embryo germination; (4) performing differentiation culture on buds; and (5) rooting and performing induced culture on the micro tubers. According to the method, different illumination intensity and culture temperature are provided in different growing stages, so that the seed embryo of rhizoma bletillae can efficiently germinate, and leaf primordium is timely differentiated to form the buds after germination; the rooting and the forming of the tubers are induced with the same culture medium, so that the seed germination, the leaf bud differentiation, the rooting, seedling growing and the inducing of the micro tubers are synchronously performed, and as a result, the inducing rate is high; the quality of the seeds and the seedlings is high; the transplanting survival rate is high; the high-quality production of the seeds and the seedlings of rhizoma bletillae is achieved; the wild resource can be effectively protected and rescued; and moreover, the demand on mass production is met.
