Abstract

The invention discloses a method for testing the growth of fungal hyphae in plant stems. The method includes the following steps: (1) taking a glass tube with a diameter of 10-50 mm, forming ventilation holes at intervals of 3-5 mm on the side wall of the glass tube, and controlling the diameter of the ventilation holes to be less than 0.2 mm; (2) sealing the bottom of the glass tube with a filterscreen, wherein the diameter of filter holes of the filter screen is 0.2-0.3 mm, placing the bottom of the glass tube into a culture dish, and pouring culture liquid into the culture dish; (3) pouring glass beads with a diameter of 0.4-0.5 mm into the glass tube; (4) pouring transparent nutrient solution inoculated with the hyphae into the glass tube filled with the glass beads, pouring once every 20-30 hours, and continuously pouring 1-2 times; (5) placing the glass tube together with the culture dish into a culture chamber for culture for 7-20 days; (6) observing and recording the growth ofthe hyphae in the glass tube to obtain a growth mode of the hyphae. The method is used for researching the growth condition of the fungal hyphae when fungal pathogens cause stem mycosis of gramineousplants.

Description

technical field [0001] The invention relates to a plant stalk simulation test method, in particular to a test method for fungal mycelium growth in plant stalks. Background technique [0002] In scientific research, it is often necessary to simulate the growth of grass plant stems to understand the growth of fungal diseases in grass plant stems. [0003] However, the prior art still lacks a test method for studying the growth of fungal hyphae in plant stems. Contents of the invention [0004] Purpose of the invention: Aiming at the deficiencies and defects of the prior art, the present invention provides a method for testing the growth of fungal hyphae in plant stems when fungal pathogens cause mycotic diseases of gramineous plant stems. . [0005] Technical solution: A method for testing fungal hyphae growth in plant stems of the present invention is characterized in that it includes the following steps: [0006] (1) Take a glass tube with a diameter of 10 mm to 50 mm, ...
