Embodiment 1

[0040] (1) According to the formula MS + NAA1.0mg / L + 6-BA1.5mg / L + sucrose 30g / L + fresh clematis 0.5g / L, adjust the pH value to 5.8, prepare the culture medium, and wrap the reactor, high temperature, high pressure and damp heat ready for use after sterilization;

[0041] (2) Using wild clematis stems as explants, aseptic treatment:

[0042] Cleaning: Select healthy and disease-free plants, remove the roots, soak in potassium permanganate solution for 10 minutes, and then wash with running water for 60 minutes;

[0043] Disinfection: In a sterile environment, remove the leaves of the above-mentioned cleaned plants, soak the stems with 75% alcohol for 30 seconds, wash them twice with sterile water, then soak them with 0.1% mercury chloride for 20 minutes, and wash them with sterile water for 5~ 7 times.

[0044](3) Remove the leaves from the aseptically treated stem and cut it into several stem segments each containing a stem node, first inoculate it into MS solid medium, a...

Abstract

The invention belongs to the field of a traditional Chinese medicinal material, and particularly relates to a method for carrying out tissue cultivation propagation of anoectochilus roxburghii by an intermittent submerged bioreactor. The method comprises the steps of early-stage preparation, explant selection, and aseptic treatment, inoculation, cultivation of the bioreactor, and the like. Multiplication and rooting and strong seedling cultivation are finished one time in the reactor; the method has the characteristics of being short in period, high in tissue culture seedling quality and the like; and a method with low cost and high efficiency is provided for rapid propagation of tissue cultivation of the anoectochilus roxburghii.

Description

technical field [0001] The invention belongs to the technical field of tissue culture of medicinal plants, and in particular relates to a method for rapidly multiplying Aurea clematis tissue culture by using an intermittent immersion bioreactor to obtain high-quality seedlings. Background technique [0002] Anoecthilus roxburghii (Anoecthilus roxburghii) is a perennial herbaceous plant of the genus Orchidaceae, also known as Anoecthilus, Anoecthilus, Anoecthilus, and Anoecthilus. It usually grows in the fertile leaf-rotted soil under the shady broad-leaved forest. It is a traditional precious medicinal material in my country. It has the effects of cooling and detoxifying, nourishing yin and reducing fire, reducing inflammation and relieving pain, and has no toxic and side effects. It is known as the "King of Medicine" among the people. reputation. The plant height of clematis is 8~20cm, the plant type is small and exquisite, the leaf shape is beautiful, the leaf veins are go...
