Characterization of plant pathogenic bacteria associated with premature dying of apricot trees in the Czech Republic.

Original language description

Sixty two isolates of fluorescent pseudomonads were isolated from infected apricot trees on tree localities in south Moravia. Of the 54 fluorescent pseudomonads isolated, 94% were identified as Pseudomonas syringae pv. syringae van Hall (Pss) and 6% as Pseudomonas fluorescens (Trevisan) Migula 1895 (Pf). None of fluorescent isolates belonged to Pseudomonas syringae pv. morsprunorum (Wormald 1893) Young, Dye & Wikie 1978 (Pmp). Of the 25 isolates that expressed ice nucleation activity, 88% ranged to Pssand 12% to Pf. In pathogenicity test on immature cherry fruits, all Pss isolates were pathogenic and all Pf isolates were non-pathogenic. Pss isolates showed slight differences in biochemical characteristics (e.g. in utilisation of L-histidine, psicose and D,L-carnitine and in gelatine liquefaction) as well as in pathogenicity (according to size of necrosis in immature sweet cherry tees) and ice nucleation activities. Some Pss isolates nucleated ice at temperature as warm as -1°C, another
