| Abstract:
Elm leaves were collected and analyzed for their flavonoids and phenolic acids content after the infection with Ophiostoma ulmi. Genotypes with different resistance level to Dutch elm disease belonging to three elm species were analyzed. A different behaviour is shown by the three species from 1 to 8 days after the infection. Flavonoids amount mostly increased while the phenolic acid concentration decreased in the two resistant species. However the role played by these compounds in the plant/pathogen relations needs more experimental work to be explained. | |
