Abstract

The invention discloses a method for establishing a rapid propagation system of tripterygium hypoglaucum. The method comprises the following steps: seeding terminal buds or axillary buds of tripterygium hypoglaucum into an induction culture medium to induce sprouting, subsequently transferring and transplanting small buds of tripterygium hypoglaucum into a subculture medium and a rooting medium in sequence to culture continuously, thereby obtaining root tissue culture seedlings of tripterygium hypoglaucum, and further transplanting the root tissue culture seedlings into a seedbed to harden the seedlings. The tissue culture method disclosed by the invention is simple and convenient, simple in step and convenient to operate, the prepared tripterygium hypoglaucum seedlings are healthy and strong, high in growing ability and applicable to large-scale production, the culture time is effectively shortened and the production cost is also lowered.

Description

technical field [0001] The invention relates to a method for rapid propagation of plants, in particular to a method for establishing a rapid propagation system of Kunming mountain crabapple. Background technique [0002] Kunming mountain crabapple (Tripterygium hypoglaucum (Lv.1) Hutch) is a deciduous woody vine of the genus Tripterygium in the family Celastraceae. In "Southern Yunnan Materia Medica", "Zijinpi" is its drug name; Kunming mountain crabapple is commonly known as "torch flower", which was first recorded in Li Shizhen's "Compendium of Materia Medica" in the section of poisonous weeds in the grass. Torch Flower". Different ethnic groups use the medicinal parts of the plant as roots, root bark and stems. Folks often use woody canes as medicines, or use the roots and whole plants as regular supplies of Vajra vine; root bark, young branches and leaves are often used by farmers in the countryside. Used as botanical insecticide or pesticide. Kunming Begonia is used ...
