| Abstract:
The effect of virus infection on vegetative and reproductive development of sour cherry (Prunus cerasus L.) trees on the rootstocks F12/1 (Prunus avium L.) and Damil (Prunus x dawyckensis) was investigated. Sour cherries are particularly sensitive to Prune Dwarf Virus (PDV). Infection with PDV seriously reduced the survival of the sour cherry trees, reduced vegetative growth and fruit set, and intensified bare wood formation. The commercially viable production sour cherries infected with PDV is unlikely. The effect of Prunus Necrotic Ringspot Virus (PNRSV) was less severe than PDV, but still negative. The combined virus infection (PDV+PNRSV) was devastating. The surviving trees with PDV+PNRSV barely grew and exhibited extreme bare wood formation. The negative effects of virus infections were more severe on Damil than on F12/1. | |
