Embodiment Construction

[0016] (1) Medium selection and hormone combination: MS was used as the basic medium, and different hormone combinations were used to prepare the following relevant medium:

[0017] Bud induction medium formula: MS+6-BA0.4mg.L -1 +IBA0.2mg.L -1 ;

[0018] Bud subculture proliferation medium formula: MS+6-BA0.6mg.L -1 +NAA0.5mg.L -1 ;

[0019] Rooting medium formula: 1 / 2MS+ABT 1 0.8mg.L -1 +IBA0.4mg.L -1 ;

[0020] All the above media were added with 3% white sugar and 0.35% agar, pH5.8.

[0021] (2) Selection and processing of explants: Collect materials on a sunny day, select the top buds and axillary buds of Niu Dali as explants, rinse them with tap water, cut them into 6-10cm buds, and place the explants on the ultra-clean workbench The body was soaked in 75% alcohol for 5 minutes, then sterilized with 0.1% mercuric chloride solution for 5 minutes, rinsed with sterile water for 3 to 4 times, and soaked in sterile water for later use.

Abstract

The invention provides a method for tissue culturing and reproducing the millettia speciosa champ germchit. By using the tissue culture method and taking the fresh apical bud and the axillary bud of the wild millettia speciosa champ as the explant, the explant is disinfected and sterilized by the 75 percent alcohol and 0.1 percent mercuric chloride solution; after that, according to different periods, different culture medium formulas are adopted respectively for the bud induction culture, bud subculture proliferation and the rooting culture to obtain the container seedling of the millettia speciosa champ, wherein, the bud induction culture medium has a formula of MS+6-BA0.4mg.L-1+IBA0.2mg.L-1+3 percent white granulated sugar+0.35 percent agar, the formula of the bud subculture proliferation culture medium is MS+6-BA0.6mg.L-1+NAA0.5mg.L-1+3 percent white granulated sugar+0.35 percent agar, and the formula of the rooting culture medium is 1 / 2MS+ABT10.8mg.L-1+IBA0.4mg.L-1+3 percent white granulated sugar+0.35 percent agar; moreover, when the height of the container seedling is grown about 2 cm, the container seedling is again transplanted to a seedbed of a greenhouse for culturing; after reaching over 20cm, the container seedling is the grown seedling of the millettia speciosa champ germchit.
