Plum pox virus as a stress factor in the one-yearold shoot and fruit growth and yield of plum cv. Stanley

Abstract

The stress effect of Plum pox virus (PPV) on the vegetative growth and yield of cv. Stanley was examined under the conditions of Cacak (Western Serbia) in 2006-2007. The results showed that PPV induced significant differences in one-year-old shoot length (17.00%), fruit weight (6.21%) and yield per tree and unit area (20.61%) between infected and non-infected trees.
