Abstract
  • Grafted grapevines will become increasingly important in Oregon vineyards in order to prevent loss of plants to phylloxera infestations. Several rootstocks are now being evaluated in Oregon for horticultural traits and characteristics related to wine quality. Resistance or tolerance to other plant diseases affecting grapevines needs to be examined as well. Both crown gall and nematode infestations have been shown to reduce plant vigor. In addition, nematode infestations may increase the incidence of crown gall by wounding the plant tissue. Wounds allow entry of Agrobacterium vitis, the causal agent of crown gall, into plant cells and provide sites for tumor development (7).
