Problems in detection of European stone fruit yellows phytoplasma in apricot trees in the Czech Republic

Original language description

A collection of thirty-eight trees of four apricot cultivars grown in the orchard where ESFY symptoms appeared was evaluated during the years 2004-2007. The presence of ESFY was evaluated by inspection of symptoms, PCR, and indexing on the peach indicator GF-305. Ten trees showed typical ESFY symptoms during the evaluation. Typical symptoms of ESFY, such as leaf yellowing and rolling, little leaves and sparse foliage are a reliable diagnostic criterion for this disease. Apricot trees with ESFY symptomsdied out either within one year, or during the next growth period. Twenty-five trees were without symptoms in the years 2004-2007, from which two trees were tested positive by nested PCR in four years, two trees were positive in three years, four trees in two years, seven trees in only one year, and ten trees were negative during the period 2004-2007. Results of biological indexing of twenty-five symptomless apricot trees were negative in 2004-2007. Nine apricot trees died for ESFY, and

Problémy s detekcí fytoplasmy evropské žloutenky peckovin v meruňkách v České republice

Czech description

V letech 2004-2007 byl vyhodnocen soubor třiceti osmi stromů meruňky na přítomnost ESFY vizuelním hodnocením příznaků, biologickým testem na GF-305 a molekulárním testem pomocí nested PCR. Molekulární test je nespolehlivý, výsledky biologického testu byly negativní, nejspolehlivější je hodnocení příznaků. Stromy s příznaky ESFY odumírají během jednoho, nejdéle do dvou let.
