| 摘 要： | 对香蕉受枯萎病菌Fusarium oxysporum f.sp．cubense侵染后体内赤霉酸（GA3）、吲哚乙酸（IAA）和脱落酸（ABA）3种内源激素含量的变化进行了测定．结果表明：接种的香蕉苗体内的GA3、IAA和ABA的含量均高于未接种的对照，表明香蕉枯萎病菌的侵染引起了香蕉体内GA3、IAA和ABA的积累，此3种植物内源激素与香蕉受枯萎病菌感染的病程相关． |

| 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. |
| Keywords: | bananas Fusarium oxysporum f sp cubense GA3 IAA ABA |
