dc.description.abstractThe susceptibility of seven cultivars of Japanese plum (Black Star, Gauota, Golden Japan, Crimson Glo, Ozark Premier, Santa Rosa, Vanier) and three cultivars of pluot (Black Gigant®, Dapple Supreme pluot®, Flavorich pluot®) to Pseudomonas syringae pathovars syringae and morsprunorum was evaluated under temperate European climate conditions over a three-year period. The evaluation was carried out in a netted house. The susceptibility of the plants to the causal agents of blossom and terminal shoot infection was calculated on five occasions during the year using a formula summarising all the symptoms that appeared on the plants after artificial inoculation. Most cultivars were classified in BS class 2 as low susceptible to both pathovars of Pseudomonas syringae. The Japanese cultivar Santa Rosa was the only cultivar classified in class 4, as highly susceptible to morsprunorum pathovar. After terminal shoot inoculation, 60% of the Japanese plum and pluot cultivars were classified as very low susceptible in class 1 and 40% as low susceptible in class 2 to both pathogens tested. Apart from Santa Rosa, the remaining Japanese plums and all plum cultivars showed remarkable vigour and recovery after repeated artificial infection with economically important Prunus plant pathogens.eng
