Embodiment 3

[0033] (1) Pretreatment: Take the healthy and full-bodied Chinese herbal medicine Thyme chinensis terminal buds or axillary buds, use a soft brush to add a small amount of detergent to the water, and gently wipe the branches and axillary buds, rinse with tap water for 1.5 hours, and put them in the water for 1.5 hours. In the ultra-clean workbench, sterilize with 75% alcohol for 30 seconds, wash with sterile water for 4 times, sterilize with mercuric chloride with a concentration of 0.2% for 8 minutes, and rinse with sterile water for 5 times; the surface is sterilized Germination culture is carried out by inoculating the material in a test tube filled with germination medium. Each test tube is inoculated with one terminal bud or axillary bud, and then placed in the culture room. The germination medium is: MS basal medium + 6-BA 2.0mg / L+NAA0.2mg / L+sucrose 30g / L+agar powder 5.4g / L, pH 5.8; cultured for 5 weeks at a temperature of 27°C, a light time of 16h / d, and a light intensi...

Abstract

The invention discloses a tissue culture method suitable for a Chinese herbal medicine murraya paniculata seedling. The method mainly comprises the following steps: cultivating a murraya paniculata seed or terminal bud or axillary bud on a germination culture medium to grow a germination seedling, inoculating on a cluster bud induction medium, breeding, conducting spreading cultivation, subculturing to grow a cluster bud and an adventitious bud, then obtaining a rootless plant, conducting adventitious root induced culture on the rootless plant, hardening the seedling, and then transplanting and cultivating. The culture medium is formed by adding 6-BA and NAA or GA on an MS of the germination culture medium; the cluster bud induction medium is formed by adding 6-BA and NAA or TDZ on the MS of the cluster bud induction medium; an adventitious root induction medium is formed by adding 6-BA and NAA or IBAK on the MS. The leaf of the adventitious bud of the Chinese herbal medicine murraya paniculata is thick, the stem of the adventitious bud of the Chinese herbal medicine murraya paniculata is thick and large, the adventitious bud of the Chinese herbal medicine murraya paniculata has the advantages of low aberration rate and high growth coefficient, the survival rate of the hardening seedling is up to 90%, the adventitious bud of the Chinese herbal medicine murraya paniculata is suitable for being provided as the Chinese herbal medicine murraya paniculata seedling, the cost is low, the pollution is low, and the Chinese herbal medicine murraya paniculata seedling can be produced all through the four seasons, and is suitable for large-scale culture of seedlings.
