This study evaluates the percentage of infected trees in 2010 as well as the intensity of PPV symptoms in 2011 in two peach varieties „Royal Glory“ and „Symphony“ grafted on seven different rootstocks of Prunus species after the natural infection. The different intensity of PPV symptoms was proved on infected parts such as flowers, leaves, fruits and from rootstocks’ point of view.In 2010 were PPV symptoms most often detected in variety ’Royal Glory’ grafted on rootstock Julior where 100% of trees were infected. No visible symptoms were observed in trees of variety ’Symphony’ on Pumiselect rootstock. As for the rootstocks evaluation, PPV symptoms were most numerous in trees grafted on MRS 2/5 rootstock (94.78%), at least were monitored on Lesiberian rootstock (28.47%).The intensity of PPV symptoms on flowers, leaves and fruits in each combination was evaluated in 2011. Generally, the PPV symptoms were present mainly on flowers and less on fruits. |
