Three fungus strains for promoting germination of arethusa seeds

Abstract

The invention discloses three fungus strains for promoting the germination of arethusa seeds. The classification names of the three fungus strains are respectively Rhizoctonia sp. Bsg11 with the preservation serial number of CGMCC No.2450, Tulasnella sp. Bsg14 with the preservation serial number of CGMCC No.2451 and Mycena sp. MF24 with the preservation serial number of CGMCC No.1350. The three effective fungus strains have an important meaning for solving the germination problem of arethusa seeds; and the three effective fungus strains can be seeded together with the arethusa seeds, are used for the cultivation of the cultured seedlings or the large fields of a seedling culture disk or a flowerpot or a seedbed and have an application value for replacing tissue culture to obtain seedlings.

Description

Technical field [0001] The invention relates to the technical field of bioengineering, in particular to three fungal strains that promote the germination of orchid plant seeds, which can be sown with orchid plant seeds and used for seedling raising or field cultivation in seedling trays, flower pots or seedbeds. Background technique [0002] There are many traditional and valuable Chinese medicines in orchid plants, such as dendrobium and bletilla striata. According to the 2005 edition of the Chinese Pharmacopoeia, Dendrobium has the effects of nourishing the stomach, nourishing fluid, nourishing yin and clearing away heat, and can also improve the throat and eyesight, and regulate the immune function of the human body. Bletilla striata is used as a tuber as medicine. It has the effects of astringent and hemostasis, swelling and muscle growth, etc. It mainly treats hemoptysis and vomiting, traumatic bleeding, sore swelling toxin, skin chapped, pulmonary tuberculosis, hemoptysis, ...

AI Technical Summary

Problems solved by technology

However, in practical application, when the aseptic seedlings obtained by tissue culture rapid propagation are used for cultivation, the two links of training seedlings and transplanting not only limit the popularization and application of this method in terms of technology but also production costs.

Before a breakthrough in technology in this area, it is still difficult to achieve large-scale cultivation and production of Dendrobium plants.

[0007] There are only scattered reports about the cultivation techniques of Bletilla striata, but there is a lack of systematic research, and there is no large-scale cultivation base. There are still many problems to be solved in the traditional method of asexual reproduction of wild plants.

Wild mutated species need a long domestication process, but so far there are no reports on this aspect

It is an effective way to use tissue culture to solve the problem of reproduction and germplasm preservation of endangered plants. At present, some units have carried out research on tissue culture and rapid propagation of seeds, shoot tips and lateral buds, and pseudobulbs. Aseptic seedlings can be obtained within the country, but seedling training and transplanting are a problem that limits its application. At present, there is no effective method for training seedlings and transplanting. Only after a breakthrough in this technology can it be practically applied

[0009] At present, there are few domestic and foreign research reports on fungi that promote seed germination of orchid medicinal plants, and no excellent fungi that can promote seed germination have been found.
