Abstract

The invention discloses a banana fusarium oxysporum culture medium and application thereof. The culture medium comprises the following components: 10g/L glucose, 2-8g/L aspartic acid, 5% by volume of20*nitrate, 0.5% by volume of 200*ferric salt, 0.1% by volume of 1000*vitamins and 0.1% by volume of 1000*trace elements, and the pH value of the culture medium is 6.2-6.5. By adopting the culture medium disclosed by the invention, germination of banana fusarium oxysporum conidium is promoted, interference of macromolecule proteins is avoided, and analysis on banana fusarium oxysporum secretion proteins is facilitated.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation, in particular to a culture medium for Fusarium wilt of banana and its application. Background technique [0002] Banana wilt is caused by Fusarium oxysporum Cuban specification ( Fusarium oxysporum f. sp. cubes , Foc) is a fungal disease caused by banana production, which is one of the most important diseases in banana production. It occurs in almost all banana production areas in my country. The incidence of diseased banana orchards is generally 30-50%. Reaching more than 90%, it is a serious threat to the sustainable development of the banana industry. Foc mainly invades from the roots or wounds of bananas through conidia, and then enters the vascular bundles for growth and reproduction, which leads to browning and necrosis of banana vascular bundle cells, and finally leads to the wilting of the whole banana plant. Due to the complex genetic background of Foc, its pathogeni...
