Abstract:
Under the conditions of heavy infection of Stanley plum variety with Sharka virus, we investigated the reaction of this variety to the virus.
We observed symptoms manifestation on leaves and fruits.
Rather severe symptoms appear on leaves.
Those are typical symptoms which are characteristic for Sharka.
The symptoms are less severe on fruits, as compared to other susceptible varieties of plum.
The rate of infected fruits is from 10–20%. The symptoms are less apparent and in the form of grooves and small round spots which can be found on various parts of the fruit.
