Abstract

The invention discloses a living organism inoculation conidium generating method for quickly obtaining panax notoginseng round spot pathogenic bacterium conidia. The method comprises the following steps that 1 of pathogenic bacterium culturing; 2 conidium generating device manufacturing; 3 leaf inoculating; 4 conidium inducing, wherein after inoculating is performed for about 3 days, when obviously macroscopic disease spots are formed on hypha-infected leaves, bacterium cakes are immediately removed, spray moisturizing is continuously performed, conidia are generated at the disease spots after inoculating is performed for about 6 days, the number of the conidia generated on each leaf after inoculating is performed for 10 days reaches about 104, the conidia can be washed down with sterile water in time if the conidia need to be used after the conidia are generated, 1 mL of the sterile water is sucked up with a pipettor to wash each leaf which generates the conidia, and 1 mL of conidium suspension liquid can be obtained from each leaf. Compared with the prior art, the method has the advantages that the mycocentrospora acerina conidia for scientific experiment research can be obtained in a short time, and the stability, the operability and the repeatability of an experiment can be guaranteed.

Description

technical field

[0001] The invention relates to the technical field of microbes, in particular to a living inoculation sporulation method for rapidly obtaining conidia of P. pseudoginseng. Background technique

[0002] Mycocentrosporaacerina (R.Hartig) Deighton[=Centrosporaacerina (R.Hartig) A.G.Newhall], its taxonomic status is Ascomycota Ascomycota Dothideomycetes Mycosphaerellaceae Mycocentrospora, can parasitize in Submerged plants in freshwater basins also infect terrestrial host plants and cause plant diseases. The host range of this fungus is wide and the damage is serious. In foreign countries, it mainly causes pansy leaf spot, parsley storage period rot, carrot root rot, and burdock root rot. Diseases such as canker and crown rot, the pathogen was introduced into my country in the early 1990s, infecting the medicinal plant Asarum, causing Asarum leaf blight. According to investigation reports, Panax notoginseng plants began to be infected in 1993, resulting in the ro...
