The influence of ethylene and abscisic acid on the infection of wheat seedlings by Fusarium culmorum depending on the content of calcium in the medium was investigated. It has been established that when this element does not occur in the medium ABA stimulates, whereas ethylene inhibits the development of a disease. Adding calcium to the medium decreases considerably the stimulating influence of ABA, where it increases the inhibiting action of ethylene in this process. The influence of ethylene and abscisic acid on the growth and development of Fusarium culmorum depending on the content of calcium in the medium, was also investigated. Basing on the above results it can be conc1uded that calcium in media enhances inhibitory effect of ethylene and reduces the stimulatory effect of abscisic acid on growth and development of Fusarium culmorum and also on the infection of the lings with that pathogen.

Badano wpływ ethrelu i kwasu abscysynowego na porażenie siewek pszenicy przez Fusarium culmorum w zależności od zawartości wapnia w pożywce. Stwierdzono, że przy braku tego pierwiastka w pożywce ABA stymuluje, natomiast etylen hamuje rozwój choroby. Dodanie wapnia do pożywki wyraźnie osłabia stymulujący wpływ ABA, natomiast wzmaga hamujące działanie etylenu w tym procesie. Badano również wpływ etylenu i kwasu abscysynowego na wzrost i rozwój Fusarium culmorum, w zależnos'ci od zawartości wapnia w pożywce. Na podstawie uzyskanych wyników można wnioskować, że wapń wzmaga hamujące działanie etylenu, natomiast osłabia stymulujący wpływ kwasu abscysynowego na wzrost i rozwój Fusarium culmorum oraz na stopień porażenia siewek pszenicy przez tego patogena.
