Milusheva, S. | Borisova, A.
Prunus necrotic ringspotvirus (PNRSV) and Prune dwarf virus (PDV) are among the most widespread and economical important viruses in Prunus spp. Enzyme-linked immunosorbent assay (ELISA) was used to detrmine the incidence of PNRSV and PDV in lots of stone fruit species - plum, apricot, peach, sweet cherry, sour cherry, amond and many of their rootstocks between 2000 and 2004. These viruses were found in all areas tested in South Bulgaria. Presence of range of viruses was as follows: PNRSV from 0.58 in P. mahaleb to 27.7 in sour cherry, and PDV from 1.4 in sour cherry to 15.8 in sweet cherry. Use of ELISa to monitor virus incidence in Prunus spp. is a valuable tool for reducing the incidence of viruses, which are transmitted by pollen and seeds.
