EVALUATION OF THE VIRAL STATUS FOR THE MAIN VIRUSES, OF APRICOT MOTHER PLANTATION, MENTAINED AT THE RSFG CONSTANŢA
Journal Title: FRUIT GROWING RESEARCH - Year 2018, Vol 0, Issue
Abstract
The viruses with the highest incidence of apricot are: Apple chlorotic leaf spot (ACLSV), Apple mosaic virus (ApMV), Plum pox potyvirus (PPV), Prune dwarf ilarvirus (PDV) and Prunus necrotic ringspot ilarvirus (PNRSV). The annual retesting at the RSFG Constanţa, during the 2010-2016 periods, in the mother plantation of the apricot, BASIC biological category, established in 2008, showed the infected plants. The mother plants were represented by the varieties: ‘Admiral’, ‘Augustin’, ‘Tudor’, ‘Goldrich’, ‘Sirena’, ‘The Best of the Hungary’, ‘Sulina’, ‘Mamaia’, ‘Elmar’, ‘Olimp’, ‘Ovidius’, ‘Auras’ and ‘Umberto’. Laboratory tests were done each time after visual evaluations from the mother plantation. In order to establish a more accurate diagnosis, several methods were applied: DAS-ELISA for all target viruses, and for the detection of PPV, the AgriStrip immune-chromatographic test was also applied. Also, for the detection of PDV and PNRSV viruses, the mother plants were also tested by the biological method using the ‘GF 305’ indicator. During that the mentioned period, were visually identified 9 mother plants with PPV symptoms on the leaves, the infections being confirmed by both methods laboratory testing, 2 infections with the PNRSV virus, 2 infections with the PDV virus and 1 positive sample with the ACLSV virus by the ELISA serological method. In a mother plant the infection was mixed: PDV + ACLSV. Biologically tested plants did not show symptoms on leaves that could have been associated with viral infections, as confirmed by the serological test.
