example 1

[0030] A method of tissue culture and rapid propagation of straight lip curly orchids includes the following steps:

[0031] Step 1. Take the newly germinated buds of C. serrata as explants and place them in the first culture medium to obtain sterile test tube plantlets; wherein, the first culture medium includes: Huabao No. 1 medium , 0.3mg / L methionazine, 1.5mg / L naphthaleneacetic acid, 1.5mg / L polyvinylpyrrolidone, 25g / L sucrose and 4.5g / L agar;

[0032] Step 2. Place the sterile test-tube plantlet obtained in step 1 in a second medium for culturing to obtain a clumping bud of the test-tube plantlet; wherein, the second medium includes: Huabao No. 1 medium, 0.5 mg / L A Thiadazine, 1.0mg / L naphthaleneacetic acid, 0.2mg / L kinetin, 1.5mg / L polyvinylpyrrolidone, 25g / L sucrose and 4.5g / L agar;

[0033] Step 3. Place the test-tube clumping buds obtained in step 2 in the third medium to obtain robust seedlings; wherein, the third medium includes: MS, 0.1 mg / L naphthalene acetic acid, 1.2...

Abstract

The invention discloses a method for tissue culture rapid propagation of orchid orchid orchids, comprising the following steps: step 1, taking newly germinated shoots of orchid orchid orchids as explants, placing them in the first culture medium for cultivation, and obtaining Sterile test-tube plantlets; step 2, placing the sterile test-tube plantlets obtained in step one in the second culture medium to obtain test-tube plantlets with clustered buds; step 3, placing the test-tube plantlets with clustered shoots obtained in step 2 in the third medium Cultivate to get strong seedlings; step 4, place the strong seedlings obtained in step 3 in the fourth culture medium to obtain rooted test-tube plantlets. The invention can rapidly and effectively improve the propagation speed and quality of the orchid orchid orchid seedlings, and realize industrial seedling cultivation of the high-quality orchid orchid orchid orchid seedlings, so as to meet the needs of production.

Description

Technical field [0001] The invention belongs to the field of tissue culture and plant propagation, and in particular relates to a method for tissue culture and rapid propagation of C. vulgaris. Background technique [0002] Bulbophyllum delitescens Hance (Bulbophyllum delitescens Hance) is a plant of the Orchidaceae Glycine max, with thick rhizomes, creeping roots, internodes covered by membranous sheaths or fibers remaining after the sheath rots, one at every 3-11cm interval Fake bulb. Scape originates from rhizome nodes with pseudobulbs, umbels with 2-4 flower petals sickle-lanceolate, apex is truncated and concave notch with 1 short awn in the center, with 3 veins , The whole edge. The lips are fleshy, tongue-like, and curved outwards. The flowers are unique and have a long flowering period, which is of great ornamental value. Seed reproduction is difficult to germinate due to incomplete embryo development. Coupled with the pressure of artificial excavation, the deteriora...
