Vegetative incompatibility of isolates of Phomopsis spp. from plum trees
Isolates of Phomopsis spp. obtained from plum trees (Prunus domestica L.) with symptoms of die-back. There were significant morpho-physiological and pathogenic differences between the isolates. The genetic variability (12 isolates of Phomopsis spp. and isolate of Photopia pernicious, which was used...
