| Abstract:
The present work was aimed at studying, the translocation of chlorotic leaf spot virus (CLSV) in GF-305 peach seedlings and Real Fino apricot seedlings, in comparison with the translocation of prunus necrotic ring spot virus (PNRSV). Two weeks after grafting inoculation and later on, every month before and after winter cutting back, samples of the plants were tested by ELISA-DAS method. The results show that the fruit tree species can affect, more than the virus, the speed and regularity of translocation. The two viruses spread better and more rapidly within peach than within apricot. Within each species, PNRSV translocates better than CLSV. Cutting back plants is suitable for more efficient translocation of the two viruses in peach, and of CLSV in apricot, but it is not, however, fit for PNRSV translocation towards newly grown shoots of apricot. | |
