Fungus of the family Glycobacteriaceae and its application in promoting seed germination of Paphiopedilum albicans to form seedlings

Abstract

The present invention relates to a fungus of the family Glycobacteriaceae and its application for promoting the germination of Paphiopedilum albicans seeds to form seedlings. The fungus is a strain of the family Glycobacteriaceae, Tulasnellaceae sp.GYBQ02, and its preservation number in the China Typical Culture Collection Center is: CCTCC NO: M 2020130. 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, Tulasnellaceae GYBQ02 belongs to a fungus belonging to the family Colloidalaceae, and this strain can be used to promote the germination of P. The strain is inoculated with the seeds of Papudendron alba to obtain high-quality symbiotic seedlings, and realizes the efficient cultivation of seedlings for symbiotic germination. It can be used for seedling cultivation in nurseries or field fungal seed dressing and live broadcast. Compared with tissue culture, it has low cost, high survival rate in field cultivation, and no organization. Degradation problems and other advantages, laying the foundation for the development of imitation ecological cultivation, species regression and population reconstruction of P.

Description

technical field [0001] The invention relates to a fungus of the family Glycobacteriaceae and the application thereof for promoting the germination of Paphiopedilum japonica 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...

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
