Patogeniczność wybranych form specjalnych Fusarium oxysporum względem goździków

Maria Werner, Piotr Wyrwa

Abstract


The studies were carried out on the pathogenicity of 8 formae speciales of F. oxysporum towards Dianthus caryophyllus, D. barhatus, D. chinensis and D. caryophyllus x semperflorens. The wilting was neither observed on plants growing in soil infested with F. oxyspotum f. sp. lupini nor on plants inoculated with an isolate obtained from Pinus sylvestris. However these isolates were reisolated occasionally from D. barbatus, less frequently from D. chinensis and D. caryophyllus and never from D. caryophyllus semperflorens. Only F. oxysporum f. sp. dianthi and in less degree F. oxysporum f. sp. pisi caused always the wilting off all studied carnations, while the others were responsible for occasional wilting of some plants.
