Problems solved by technology

Under heterotrophic and multitrophic conditions, small plants mainly rely on sugar in the medium as a carbon source, which can easily cause microbial contamination;
[0006] (2) Due to the presence of sugar in the medium, the surface structure of the leaves will be poorly developed, the stomatal opening and closing functions will not be strong, the leaves will be small, and the chlorophyll content will be reduced, which will eventually inhibit and reduce the pho

specific Embodiment approach

[0019] The present invention provides a specific embodiment of a method for culturing a clematis sugar-free tissue, which comprises the following steps:

[0020] ①Plant selection and aseptic treatment: choose clematis grown in June-August as the provenance (the above-mentioned clematis is preferably local wild clematis in Yongan, Fujian, and of course, clematis grown in other producing areas can also be selected lotus as the provenance), after removing the roots and leaves, cleaning and aseptic treatment, cut into small pieces of clematis with stem nodes (about 0.5-1.5cm long);

[0021] ②Cluster bud induction culture: inoculate the small section of A. clematis treated in step ① into the sugar-free induction medium, and place it in an incubator with the upper opening open for tissue induction and culture of cluster buds; the culture period is 20-60 days, The culture temperature is 20-30°C, the light time is 8-20 hours / day, and the light intensity is 50-100μmol / m 2 s; the sugar...

Abstract

The invention relates to a method for culturing sugar-free tissue of jewel orchid, which comprises the steps of: inoculating the small-segment tissue of the little sterile jewel orchid to a sugar-free induction culture medium, placing the sugar-free induction culture medium in a culture box with a top opening for carrying out tissue induction and culturing cluster buds, wherein the sugar-free induction culture medium comprises an MS culture medium, a porous inorganic material (4-10g/L), alpha-naphthylacetic acid (0.1-3.0mg/L) and 6-benzyladenine (2-4mg/L), and the pH value of the sugar-free induction culture medium is 5-6; and planting the induced cluster buds into a sugar-free strong stock culture medium, placing the sugar-free strong stock culture medium in the culture box with the top opening for culturing strong stocks, wherein the sugar-free strong stock culture medium comprises a B5 culture medium, a porous inorganic material (2-10g/L), peptone (1-5g/L), Hyponex 1 (0.1-3.0g/L), banana paste (20-150g/L) and active carbon (0.1-3g/L), and the pH value of the sugar-free strong stock culture medium is 5.5-6.0. The invention can improve the root-taking rate and the planting percent of the jewel orchid plant, and reduce the production and tissue culture cost.

Description

technical field [0001] The invention relates to a sugar-free tissue culture method of clematis clematis. Background technique [0002] Anoectochilus roxburghii (wall.) lindl is a perennial herb of the family Orchidaceae. It is also known as golden silkworm, golden thread orchid, golden thread orchid, etc. It is an endangered and rare medicinal plant, known as "golden clematis". "Grass", "magic medicine", "black ginseng" and other laudatory titles have a wide range of folk applications, and are widely used in the treatment of rheumatoid arthritis, hypertension, diabetes, kidney disease and other difficult and miscellaneous diseases, as well as for strengthening the body and post-illness. In terms of recovery from physical weakness, it is regarded as a rare and precious medicinal material in Zhejiang, Fujian, Taiwan and other provinces and Southeast Asia, especially in Taiwan Province, and is known as the "king of medicines". [0003] The seeds of clematis are tiny, consistin...
