%X The changes of polyamines and the indole acetic acid metabolism of sweet p otato cultivars with different resistance to sweet potato scab before and after inoculation were studied.The results show that the indole acetic acid content an d the polyamine oxidase activity decrease,the total content of polyamines and pu trescine increase,the ratio of putre- scine/ (spermidine spermine)increases in the leaves of both resistant and susceptible sweet potato after infected with scab f u ngus.But the change range of diseased sweet potato is more extensive than that o f anti -diseased one.The chlorogenic acid content decreases ,the indole acetic acid oxidase and peroxidase activity increase in the leaves of susceptible sweet po tato after infected with scab fungus,and the change of resistant sweet potato is contrary.
