Description
| - Results demonstrate that of three apple cultivars on the same rootstock, i.e., Early Smith, Jonagold and Gala on M.9, burrknot severity was the highest on Jonagold tree. This finding probably reflects a higher inherent predisposition of Jonagold cultivars to burrknot development because all three cultivars come trom the same nursery. Attempts at isolation of the fire blight bacterium, Erwinia amylovora, and oomycete Phytophthora spp. from necrotic tissue surrounding burrknots on rootstocks were not successful. The stem associated apple tree viruses Apple stem pitting virus (ASPV) and Apple stem grooving virus (ASGV) were detected frequently in the rootstock and scion parts of cvs. Jonagold and Early Smith and less frequently in Gala cultivar. The virus positive trees included individuals both with various burrknot severity and without symptoms of burrknots. There were no correlations between the incidence of burrknots and the presence of ASPV and ASGV.
