Sažetak
Throughout the years 2003 and 2004, 168 Prunus trees were collected and analyzed by tissue-printing molecular hybridization for the presence of Peach latent mosaic (PLMVd) and Hop stunt (HSVd) viroids. This survey was carried out in two different stone fruit growing regions, continental and coastal (Mediterranean). The sampling encompassed various cultivated stone fruit species (peach, nectarine, apricot, sweet and sour cherry), wild Prunus (P. myrabolana, P. mahaleb, P. spinosa) as well as urban ornamentals (P. cersifera, P. juliana, P. laurocerasus, P. padus, P. serrulata, P. subhirtela and P. virginiana). The collected trees were located in commercial orchards, stone fruit collections, family gardens, individual urban trees and ornamental Prunus from the Botanical Garden of the Department of Biology in Zagreb. PLMVd was detected only in nectarine and peach trees with the incidence of 94 % and 42 %, respectively. Infected nectarines were in the continental and coastal regions originating from Italy, whereas infected peaches were both from imported and native cultivars. Some of PLMVd-positive trees were confirmed by RT-PCR. None of the tested Prunus trees harbored HSVd. So far, none of the randomly tested wild Prunus or the ornamental trees have resulted viroid-positive but this survey is only the first molecular probing of the PLMVd and HSVd in Croatia. Nonetheless, it can help in developing comprehensive testing schemes and strategies for stone fruit tree viroid control.
