Abstract

The behaviour of Tomato cultures from known resistant and susceptible cultivars and lines was examined for callus growth on culture media containing increasing concentrations of Fusarium oxysporum f. sp. lycopersici race 1 culture filtrate and phytoalexin synthesis elicited by Fusarium cell wall components. A strict correlation was found between in vivo resistance to the fungus and in vitro hypersensitive response and phytoalexin induction. On the other hand in vitro tolerance to toxic filtrate does not seem in this case a good indicator of in vivo resistance to the pathogen.
