Abstract
Severe symptoms of necrosis sweet cherry fruits was recorded during 2014. in region of Šabac. About 30 % of fruits (cv. Summit) were affected and necrosis cover 1/3 of fruit surface in average. Gram negative, fluorescent, oxidative bacterial strains were isolated from diseased tissues. Symptoms similar to those, observed in natural infection were recorded on artificial inoculated cherry fruits (cv. Summit and cv. Summbarst). Isolated strains were HR positive, oxidase, pectinase, arginin dehidrolase negative and levan positive (LOPAT +---+). Same characteristics also own check strains Pseudomonas syringae (CFBP 11). According obtained results it was concluded that necrosis of sweet cherry fruits is caused by Pseudomonas syringae. Further characteristic in order proper detection of pathogens, including molecular methods are underway.
U radu su prikazani rezultati proučavanja sojeva bakterija izolovanih iz nekrotičnih plodova trešnje sorte Samit (područje Šapca). Nekroza zahvata u proseku oko 1/3 ploda koji potpuno gubi tržišnu vrednost. Bolešću biva zahvaćeno oko 30% plodova. Primenom standardnih bakterioloških metoda (izolacijom na hranljivim podlogama), proverom patogenosti i proučavanjem bakterioloških karakteristika, zaključeno je da pomenute simptome prouzrokuje fitopatogena bakterija Pseudomonas syringae, široko rasprostranjen patogen naročito koštičavih voćaka.
