Abstract
Attempts were made to transmit the prune pseudo-pox fruit symptoms from one cultivar to the same and to others.
Not infected, heat treated, healthy indicators showed mild pseudo-pox symptoms.
Symptoms on certain indicators became significantly more severe when they were infected with a source that had necrotic ring spot and chlorotic leaf spot.
These virus combinations obviously weaken the indicators quite severely.
We conclude that pseudo-pox is a genetic-physiological disorder and not a virus disease, although it may be influenced by certain virus combinations.
The typical sunken-in blotches of the cultivar Ersinger are also not caused by a virus but of a genetic-physiological origin.
