Sažetak:
Phytoplasma 'Ca. Phytoplasma ulmi’ is causal agent of elm yellows (EY) and ascomycete Ophiostoma novo-ulmi causes Dutch elm disease (DED). These are serious and widespread elm diseases, although for European elms DED is considered major treat compared to EY. In order to investigate influence of these pathogens on significant loss of elms observed in Croatia, samples of three elm species: Ulmus laevis, U. minor and U. glabra, from six location were collected during June and July of 2012. High incidence of infection, around 40% for each pathogen, was observed. Also, mixed infection caused by both pathogens was proven in 5.8% of analyzed samples. However, the frequency of single pathogen infection for individual elm species differed. 'Ca. Phytoplasma’ was infecting U. laevis more often than U. minor, while infection of U. glabra was not detected. Ophiostoma novo-ulmi infection was proven for all three elm species, but the frequency of infection was significantly higher for U. minor and U. glabra than for U. laevis. All trees infected with O. novo-ulmi were severely symptomatic, while phytoplasrna didn't cause significantly different intensity of symptoms compared to uninfected trees. Therefore, DED could have greater impact on the decline of elm trees in Croatia, especially of U. minor and U. glabra. Nonetheless, high incidence of EY phytoplasma should not be ignored and possibility of mutual interactions of these elm pathogens in natural populations should be further studied.
