Stem graining

A vine stem grooving disease; see under Rugose Wood-Complex.

English name (short RW) for a group of vine wood diseases that are presumably caused by viruses. These include corky bark disease, stem grooving and stem pitting. The causes have not yet been fully clarified; presumably, they are virus groups such as Grapevine clostrovirus A and B and various leaf roll virus complexes. All these diseases lead at least to a reduction in yield and a significantly reduced life span of the vines. The transmission or spread of the diseases occurs (at least in Europe) mostly during grafting through infected rootstocks (rootstocks) or scions (tops). Only in Mexico and the southern USA is there evidence of scale insect transmission (Corky bark). The symptoms of the different diseases are very similar, because wood and bark are affected by the infection
