Embodiment 1

[0020] (1) Disinfection of materials: Cut off the tender stem sections with terminal buds or tender stem sections with nodes from the wild Sagittarius plant, and rinse the materials with tap water; operate under aseptic conditions, first disinfect with 75% alcohol for 10s, and then Soak in 0.1% mercuric solution for 10 min, and finally rinse with sterile water for 5 times. Drain the water and put it in a sterile petri dish for later use;

[0021] (2) Culture medium:

[0022] 1) Preparation of media for three different growth stages:

[0023] Cluster bud induction medium: MS + 0.5mg / L BA + 0.2mg / L NAA, white sugar 30 g / L, agar 0.7%, pH 5.6.

[0024] Cluster bud proliferation medium: MS + 2.0mg / L BA + 0.2mg / L NAA, white sugar 20 g / L, agar 0.6%, pH 5.6.

[0025] Rooting medium for strong seedlings: 1 / 2MS + 0.1mg / L NAA + 0.1mg / L IBA, activated carbon 0.2%, white sugar 15 g / L, agar 0.5%, pH 5.6.

[0026] 2) Cut the sterilized spare material under sterile conditions into several...

Abstract

The invention discloses a rapid seedling method of medicinal sarcopyramis bodinieri calluses, and the method comprises the following steps of: (1) disinfecting taken materials; (2) cultivating the disinfected materials on a culture medium; and (3) transplanting and planting seedlings. The method comprises: taking the stem section of the tail end of wild sarcopyramis bodinieri as an explant, inoculating the stem section containing a node to the culture medium for growing under sterile condition, and then breeding into a large amount of sarcopyramis bodinieri seedlings through transplanting a plurality of times. Results indicate that the monthly proliferation rate of the calluses is 4-5 with the most appropriate culture medium and in the appropriate culture environment; each seedling averagely has 5.8 leaves and 4.8 roots; the tissue culture seedlings grow well after being transplanted to a matrix; and the survival rate of the plants in a moth is above 98%. The method provided by the invention is simple in operation and convenient in actual popularization and application.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for rapidly growing seedlings of medicinal spay grass buds. Background technique [0002] Sarcopyramis bodinieri Levl. Et Van is a wild peony plant, which grows under dense forests, damp places or rock crevices in valleys at an altitude of 1000-2450m. "Chinese Materia Medica" records: Styrofoam clears heat and dampness; reduces swelling and detoxification. Mainly heat-toxin blood dysentery; heat-damp diarrhea; cough due to lung heat; conjunctival congestion and swelling pain; vomiting blood; furuncle swollen toxin; trauma redness and swelling; venomous snake bite. It has the best curative effect when used in the folk to treat acute hepatitis (hepatitis A, hepatitis B in the acute phase), and it is also effective for chronic hepatitis and hepatitis B virus carriers. The sales volume is relatively large in Fujian and southern Fujian, and the wild resources are cu...
