Abstract

Erwinia amylovora is the most damaging bacterial disease of quince, causing a lot of damage to this crop. In cases of severe infections, this disease could even cause the death of the tree. The climatic conditions in Bistrita region were favourable for fire blight outbreak in 2022, and gave us the opportunity to study the differences manifested by five quince cultivars ('Aromate', 'Aurii' 'Bereczki', 'Adonia' and 'Cedonia') when naturally infected with Erwinia amylovora Burrill. The second wave of infections, in September, was significantly less damaging than the first one which occurred in June. Overall, after assessing the frequency of the blighted shoots of the mentioned quince cultivars, in June and in September of the year 2022, we concluded that there were significant differences between responses to natural infection Erwinia amylovora of these cultivars. The data showed that the cultivars 'Aromate' and 'Aurii' have a better behaviour than the Hungarian cultivar 'Bereczki', while the Romanian cultivars 'Adonia' and 'Cedonia' appeared to be very susceptible under the climatic conditions of the year 2022 in Bistrita area.
