Sharka disease, caused by plum pox virus (PPV), is one of the most important and destructive viral diseases of stone fruit trees of the genus Prunus. This study aimed to investigate the effect of PPV infection on hormonal profile in stone fruit trees including peach, apricot, plum, and almond. The method of investigation included measurement of the concentration of some plant hormones using high-performance liquid chromatography (HPLC) techniques. The results showed that inoculation with PPV-D virus resulted in a decrease in cytokinin tZ concentration in all plants examined. This decrease was significant in "GF305" peach. Also, the concentration of isopentenyl adenine (iP) in "Real fino" apricot increased significantly after inoculation. GA1 concentration was observed only in the control "Pollizo" plum. GA3 concentrations significantly decreased in the inoculated "Garrigues" almonds and "Pollizo" plums. GA4 concentrations in "Rojo Pasión" apricot and "GF305" peach were lower in infected plants than in the control, but "Z506-7" apricot showed a significant increase after inoculation. "Garrigues" almond, "Z506-7" apricot and "GF305" peach showed a significant increase in IAA concentrations after inoculation. ABA concentrations in infected "Real fino" and "GF305" and SA concentrations in infected "Garrigues", "Real fino" and "Pollizo" significantly increased. In "GF305", JA concentration in the infected treatment was significantly reduced compared to the control treatment. Conversely, in "Garrigues" and "Pollizo", JA concentrations in the infected treatments was significantly increased. The results of this study showed that PPV infection can have different effects on the hormonal profile of stone fruit trees depending on the species
