Stonefruit treeswere surveyedfrom Juneto
october (2003and 2004) to determinethe incidenceof
viroid, phytoplasma, and fungal diseases in theeastern
anatolia region ofturkey.Molecularhybridisationtest
(tissue printing and dot-blot) was used to investigate
the presence of Peach latentmosaicviroid(plMVd)
and Hop stunt viroid(HSVd). a total of 16 trees out
of 491 were positive for viroids. plMVd was found
in 15 peaches (Prunuspersica) (3%) and a unique
HSVd isolate was found only in an apricot (Prunus
armeniaca) tree (0.1%). the average incidence of
viroid infection was 3.2%. HSVd was detected for
the first time in eastern Anatolia, whereas no PLMVd
infection was encountered in the main apricot growing
provinces (Malatya, elazig). p c r analyses of the few
symptomatic apricots for the presence of "Candidatus
phytoplasma prunorum" were negative. isolates of
Armillaria mellea, Cytospora spp., Monilinia laxa,
Stigmina carpophila, Chondrostereum purpureum,
Fusarium spp.,Rosellinia spp., andPhytophthora spp.
were identified from symptomatic samples collected
from the region.
