Abstract
The content change of three endogenous hormones in bananas infected by Fusarium oxysporum f. sp. cubense was studied. The results showed that the contents of GA3, IAA and ABA in the infected banana tissues were higher than those in the corresponding non-infected banana tissues during the interactions of bananas with F. oxysporum f. sp. cubense. It was suggested that the accumulations of GA3 , IAA and ABA in banana plant occurred during the infection of F. oxysporum f. sp. cubense, indicating these three endogenous hormones related to F. oxysporum f. sp. cubense pathogenesis.
