Spore production method of colletotrichum gloeosporioides

Abstract

The invention provides a spore production method of colletotrichum gloeosporioides. The method comprises the following steps: step 1: inoculating colletotrichum gloeosporioides onto a medium, and performing light-dark alternate culture in a constant temperature incubator till the colletotrichum gloeosporioides almost grows all over the medium; step 2: adding a small amount of sterile water in a sterile operation platform, scraping surface aerial hyphae with a sterile glass rod and pouring out the surface aerial hyphae, covering a culture dish cover, and ensuring that a culture dish is upward to be irradiated under ultraviolet lights; step 3: then performing light-dark alternate culture again in the constant temperature incubator, so as to obtain a large quantity of spores. According to themethod, a large quantity of spores can be obtained within 12 to 20d, the sporulation quantity is 10 to 20 times that of not treated colletotrichum gloeosporioides, and a large quantity of spores canbe obtained in a short time.

Description

technical field [0001] The invention belongs to the field of biological technology, and in particular relates to a spore-producing method of gliospora anthracis. Background technique [0002] Walnut anthracnose has the characteristics of long incubation period, short onset time, and strong explosiveness. It can cause fruit necrosis and fruit drop, leaves scorched and fall off, and also harm young shoots, seriously affecting walnut yield and quality, and causing serious economic losses. a catastrophic disease. Most scholars in my country believe that the asexual generation of the walnut anthracnose pathogen belongs to the half-know fungus, Colletotrichum Corda (C. gloeosporioides Penz). [0003] In the spore research experiment and spore inoculation experiment of glyospora anthracnose, it is often necessary to obtain a large number of spores in a short period of time, because it takes 15-60 days for the gloeosporin anthracnose to start spore production under the growth condi...

Problems solved by technology

[0003] In the spore research experiment and spore inoculation experiment of glyospora anthracnose, it is often necessary to obtain a large number of spores in a short period of time, because it takes 15-60 days for the gloeosporin anthracnose to start spore production under the growth condition of PDA medium, and the spore production Fewer, not conducive to the development of experiments, and increase a lot of work
