The fungus of the genus Glycobacterium and its application in promoting the germination of Paphiopedilum albicans seeds to form seedlings

Abstract

The present invention relates to fungus of the genus Glycobacterium and the application thereof for promoting the germination of Paphiopedilum japonica seeds to form seedlings. Tulasnella sp.GYBQ01, its deposit number in China Center for Type Culture Collection is: CCTCC NO: M 2020129. The invention provides the morphology and physiological and biochemical characteristics of the bacterial strain. According to the results of morphological, physiological, biochemical and nucleotide sequence analysis, Tulasnella sp.GYBQ01 belongs to a fungus belonging to the genus Pleurotus genus of the family Glycobacteriaceae. This strain can be used to promote the germination of P. chinensis seeds to form seedlings. It has strong specificity. It can be used to inoculate P. Symbiotic seedlings, high-efficiency cultivation of seedlings to achieve symbiotic germination, can be used for seedling cultivation in nurseries or field fungal seed dressing and direct seeding. Compared with tissue culture, it has the advantages of low cost, high survival rate in field cultivation, and no tissue degradation. It lays the foundation for the imitation ecological cultivation, species regression and population reconstruction.

Description

technical field [0001] The invention relates to a fungus of the genus Glycophaga and the application thereof for promoting the germination of Paphiopedilum papillosa seeds to form seedlings, and belongs to the field of applied microorganisms. Background technique [0002] Paphiopedilum alba ( Paphiopedilum spicerianum ), was first found in Assam in northern India, and later in northeastern India along the border with Myanmar. The sepals in the flowers are large and white, like a white flag, the upper part is curved forward into an arch, and the pseudostamens are ear-shaped and heart-shaped, which has high ornamental and breeding value. In 2006, in Pu'er City, Yunnan Province, my country, the wild distribution of P. albicans was discovered for the first time, and it is also the only confirmed wild distribution point in my country. There are only more than 20 plants in the original population. This species grows on the steep bank of a small river ditch at the entrance of an ...

Problems solved by technology

At present, effective fungi are mostly obtained by isolating from the roots of wild plants of Orchidaceae, but because there are a large number of endophytic fungi with unknown functions in the roots of Orchidaceae, this makes the screening and isolation of effective fungi for seed germination complicated and cumbersome. , meanwhile, whether the fungi in the roots of different orchids are the same as the effective symbiotic fungi at the seed germination stage is still uncertain
