During the years 2003-2007, 61 peach, 20 apricot, and 19 plum varieties, after chip budding inoculation with PPV-M strain, grown in the screen house, were surveyed for symptom expression on leaves, flowers and fruits. A large number showed discoloration and mottling on the young leaves in spring. Furthermore, many peach varieties with rosaceous flowers appeared infected displaying strong symptoms on petals. Some peach and apricot cv., but only one plum variety, presented fruit deformations with typical rings and mottling. Only a small number (24 varieties) neither apparently demonstrated typical symptoms, nor resulted positive during ELISA and Real time PCR assays. These plants were reinoculated with the same PPV isolate and subjected to further observations.

Abstract
During the years 2003-2007, 61 peach, 20 apricot, and 19 plum varieties, after chip budding inoculation with PPV-M strain, grown in the screen house, were surveyed for symptom expression on leaves, flowers and fruits. A large number showed discoloration and mottling on the young leaves in spring. Furthermore, many peach varieties with rosaceous flowers appeared infected displaying strong symptoms on petals. Some peach and apricot cv., but only one plum variety, presented fruit deformations with typical rings and mottling. Only a small number (24 varieties) neither apparently demonstrated typical symptoms, nor resulted positive during ELISA and Real time PCR assays. These plants were reinoculated with the same PPV isolate and subjected to further observations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
