Abstract

The isolation of pathogen, A. tumefaciens, was successful first from the buds, callus tissue and fresh root-tips of forced short cuttings made from symptom-free canes, and furthermore from fresh root-tips and callus tissue of forced, symptomfree root pieces.
Both the canes and roots were collected from natural infected, self-rooted vines (cuttings). The results give further evidence regarding systemic spreading of the pathogen in the vascular system of grapevine and to its transmissibility by vegetative propagating material. The tumor-formation on green-wood grafted vines, of which the shoots were collected in a vineyard which was more than 25 percent infected with crown gall, gives further convincing evidence.
