Problems solved by technology

At present, the group cultivation of clematis seedlings is mainly realized through three stages of "induction of adventitious buds, bud proliferation and strong seedling cultivation". The cultivation time is long and the cost is high, which has caused the production of clematis to be unable to get faster. development of

Abstract

The invention discloses a rapid propagation method of culturing medical anoectochilus roxburghii tissue through which seedling is formed in only one step. The invention mainly consists of the flowing steps: firstly, culture medium is prepared by three steps of preparation, prepackaging and sterilization; secondly, explant is treated and inoculated, which step has two conditions: when a natural growth plant is used as an explant, the step consists of three steps of cleaning, sterilizing and inoculation, and when a tissue culture sterilized seedling is used as an explant, the sterilized inoculation is directly carried out; thirdly, cultivation; and fourthly, transplantation. The invention uses the middle stem of an anoectochilus roxburghii plant, which is produced by subculture, as an explant. A stem section which contains a stem node is inoculated on culture medium under sterile condition. The results show that after the optimum culture medium is cultured for four months, the average seedling number of each explant is 4.8; the average net increased number of the leaves of each plant is 3.6; the average increased root number is 2.5 and the average net increased fresh weight is 525.6mg. The growing condition of the tissue culture seedling is quite good after being transplanted to substrate. The survival rate of plants achieves to above 95 percent after three months. The invention can greatly shorten the tissue culture seedling time of anoectochilus roxburghii, significantly improve the culture efficiency and reduce the seedling cost. The invention can be used as an important method of producing anoectochilus roxburghii seedlings.

Description

technical field [0001] The invention relates to a one-step seedling rapid propagation method for medicinal clematis tissue culture, which is mainly used for the tissue culture of medicinal clematis. Background technique [0002] Anoectochilus roxburghii (wall.) lindl] is a perennial herb of the family Orchidaceae, also known as golden silkworm, golden thread orchid, golden thread orchid, etc. It is a traditional and precious medicinal material in my country, known as "golden grass", "Miraculous medicine", "black ginseng" and other good names have a wide range of folk applications, and are widely used in the treatment of rheumatoid arthritis, high blood pressure, diabetes, kidney disease and other difficult and miscellaneous diseases, as well as physical fitness, recovery from physical weakness after illness, etc. On the other hand, especially in Zhejiang, Fujian, Taiwan and other provinces and Southeast Asia, it is regarded as a rare and precious medicinal material, especially...
