| Abstract: | Summary Greenhouse experiments demonstrated a differential interaction between potato viruses X and Y in two potato cultivars. Enhancement
of PVX synthesis in doubly infected plants occurred only in the PVY-susceptible potato cv. Ulla, whereas PVX multiplication
was almost completely inhibited in the doubly infected PVY-resistant cv. Franzi. However, a synergistic effect was also evident
in the latter cultivar in the form of a growth inhibition of the plants. An increased multiplication of one or both of the
viruses is, therefore, not related to a synergistic reaction. |
