Problems solved by technology

However, the basidiospores of Zizhi that have not germinated cannot produce primary hyphae, so it is impossible to breed Zizhi varieties by means of hybridization, protoplast fusion or mutagenesis.
Zizhi spores have two layers of walls, which are very tough, and it is difficult to break them by general chemical and physical methods; it is very difficult to germinate in nature, and the germination rate is extremely low under laboratory conditions
Thereby restricting the breeding of new varieties of Zizhi
[0004] Although the use of protoplast monokaryonization technology can solve the problem that the germination rate of the basidiospores of Zizhi is extremely low and the monokaryotic strains are not easy to obtain, but the monokaryotic strains obtained by the protoplast monokaryonization technology do not have meiosis. The resulting monokaryotic strains were not rich in genetic diversity
Therefore, it is difficult to obtain new strains with extensive variation through protoplast mononuclearization technology

Abstract

The invention belongs to the technical field of edible fungus breeding, and relates to a germination medium for basidiospores of Zizhi basidiospores and a germination method for basidiospores of Zizhi. Each 1000mL of the germination medium includes the following components: 160-240g of potatoes, 10-20g of glucose, 3 sucrose -8g, MgSO 4 0.8-1.5g, KH 2 PO 4 0.3-0.8g, 1.5-2g of agar powder, 150-200mL of Zizhi decoction, 40-80μL of glacial acetic acid, and distilled water as the balance. The invention provides the germination medium of the basidiospores of Zizhi lucidum by adding a specific content of glacial acetic acid to make glacial acetic acid and potatoes, glucose, sucrose, MgSO 4 、KH 2 PO 4 The combination of the agar powder and the boiled liquid of Zizhi increases the germination rate of basidiospores of Zizhi to 6.50%. The method for germination of basidiospores of Zizhi using the basidiospore germination medium of Zizhi is simple, easy to operate, and easy to popularize and apply on a large scale.

Description

technical field [0001] The invention belongs to the technical field of edible fungus breeding, and relates to a germination medium and a germination method of basidiospores of edible fungi, in particular to a germination medium and a germination method of basidiospores of Zizhi. Background technique [0002] Zizhi belongs to Basidiomycotina, Phytomycetes, Polyporaceae, Ganodermaceae, and Ganoderma genus. Zizhi is flat and warm. Non-toxic, slightly bitter, without any side effects. It is mainly used to treat diabetes, high blood pressure, coronary heart disease, insomnia and other diseases. Long-term use can resist tumors, protect the liver, delay aging, strengthen the body, and is beneficial and harmless to the human body. It is suitable for long-term health care. [0003] As a species of Ganoderma lucidum, Zizhi is also a quadrupolar heterothallic combination, that is, two different nuclei coexist in the hyphae of one cell to undergo reproductive growth and form fruiting ...
