Abstract: The High-performance Liquid Chromatography(HPLC)was used to determine the content of 10 phenolic acids in root exudates of susceptible and resistant banana cultivars(Brazilian and Nantianhuang),and the phenolic acids with obvious content differences in different treatments were selected to verify its inhibitory effect on the growth of Foc4. The study found that after induction with Foc4,p-hydroxybenzoic acid and cinnamic acid were detected only in the root exudates of resistant cultivar,and the content of phthalic acid in disease resistant cultivar was nearly twice that disease susceptible cultivar,and the inhibition rate of phthalic acid,p-hydroxybenzoic acid and cinnamic acid on the growth of Foc4 increased significantly with increasing concentration. The result also showed that there was a close correlation between phenolic acids from banana root exudates and banana cultivar resistance,which provided a certain theoretical basis for the subsequent selection of banana Fusarium wilt resistant varieties.
