Special culture medium for improving tissue culture propagation speed of haworthia succulent plants and tissue culture method

Abstract

The invention provides a special culture medium for improving the tissue culture propagation speed of haworthia succulent plants and a tissue culture method. The special culture medium is characterized in that the ingredients of the special culture medium include a basic culture medium and low-dosage 2,4-D. The tissue culture method comprises the following steps of 1 explant selection and sterilization, 2 inoculation and aseptic strain establishment and 3 transfer and expanding propagation. The problem of low tissue culture propagation speed of the haworthia succulent plants can be solved, the propagation speed of the haworthia plants is remarkably improved, the cost of the whole tissue culture is reduced, and the marketing speed of products is improved.

Description

technical field

[0001] The invention relates to the field of biological propagation, and mainly relates to a special culture medium and a tissue culture method for increasing the tissue culture propagation speed of succulents of the genus Twelve. Background technique

[0002] Haworthia Dural is a perennial herbaceous small succulent plant belonging to the Aloe family of Liliaceae. It was named in honor of Adrian Hardn Haworth, a British botanist in the early 19th century. The genus is divided into Two types of hard leaves and soft leaves.
