The resistance of individual trees seems to be important for the maintenance of ash in European forests. In this in situ wound inoculation study, the susceptibility and differences in resistance to H. fraxineus between Fraxinus excelsior and F. angustifolia clones were assessed. Neither...
Rice blast fungus (Pyricularia grisea) is one of the most problematic pathogen to significantly reduce rice production worldwide. In this study, after being inoculated with P. grisea, changes in phenolic components and antioxidant capacity and correlation with the resistant level against rice blast fungus were investigated. Among screened rice cultivars, AV-3 was the strongest resistant, whereas BII-3...
Przeprowadzono badania odporności 55 dzikich gatunków Nicotiana, 5 form autotetraploidalnych i 29 odmian botanicznych na Thielaviopsis basicola (Berk. and Broome) Ferr. Badania prowadzono w warunkach szklarniowych metodą hydroponiczną, gdzie rośliny rosły w styropianowych tacach pływających w obiekcie z dodawanym inokulum i w obiekcie kontrolnym. Po 5 tygodniach określono stopień porażenia poszczególnych...
