Abstract
Among other constitutive phenols, 3-hydroxyacetophenone has been detected in an uninfected carnation cultivar totally resistant to Fusarium oxysporum f. sp. dianthi, a fungus known to cause the main disease affecting this plant species. In both in vivo and in vitro experiments, the isolated compound proved very active in restricting parasite development. Thus, 3-hydroxyacetophenone, as a preformed and constitutive component of the uninfected cultivar, can be considered as a carnation phytoanticipin.
