In the greenhouse experiments inoculations were carried out on seeds or soil; in the field experiments evaluation was performed on onion sets from plants grown in naturally infested soils. Akgun 12 and to a lesser extent Rossa Savonese were resistant to the disease at the bulb stage in all experiments. Results were also consistent with those obtained from a previous screening at the seedling stage. Onion sets were also extracted and fractionated by thin layer chromatography to determine their content of antifungal compounds. Extracts were characterized by the expression of distinct antifungal components, which may be involved in resistance to the pathogen.en10.1007/BF02979850info:eu-repo/semantics/closedAccessAllium Cepa L.Antifungal CompoundsFusarium Oxysporum F.Sp CepaeGreenhouse TestsField ExperimentsResistanceF-Sp CepaeCultivarsInfectionFungiArticle324388394Q3WOS:0002235202000112-s2.0-9344248384Q2
