Abstract
The present study was conducted on 106 leaf samples of Prunus species (44
plum, 47 myrobalan plum, 10 apricot, 3 peach, 1 blackthorn, and 1 sour
cherry) collected from the Vojvodina province of Serbia and assessed for the
presence of Plum pox virus (PPV) with the aim of establishing whether trees
growing along roadsides and in backyards could be sources of PPV infection
in commercial orchards. Analyses confirmed PPV infection in 68.2%, 38.6%,
and 20% of plum, myrobalan plum and apricot samples, respectively. The
infection level varied considerably across locations, with 80% noted in
Uljma, followed by 69% in Sremska Kamenica, 60% in Becej, 50% in Temerin,
50% in Senta, 40% in Petrovaradin, 31% in Novi Sad, 30% in Susek, and 20% in
Subotica. As no difference in infection rates was noted between young and
older plum trees, the infections seemed to have occurred in their early life
stage. Trees growing along roadsides were infected to a higher extent
(89.6%) than those in backyards (66.6%). In some cases, symptomless trees
were also proven to be PPV positive, indicating that they are a potentially
important source of further virus infections. Due to the widespread presence
of the virus, tolerant or hypersensitive cultivars are recommended for
planting new orchards.
