Latin name for the knot (Ez. Nodium, German knot) to the exaggerated of vine, Each shoot is divided into the somewhat thickened nodes and the internodes in between (shoot axes). The medullary canal runs through each internode and runs through the node at every node of all varieties of the vine subgenus Vitis diaphragm (Tissue plate = partition) is interrupted. This division into drive links increases the static strength of the long drive. In addition, arise at the nodes leaves. tendrils, Notes and eyes (Buds). The length and thickness of the drive links depends on the vine, the growth conditions and the nutrient supply as well as the position on the shoot. At the top of growing shoots, the nodes naturally remain close together until the process of internodial length growth is completed by cell stretching and cell division and the shoot section becomes woody.
At the end of growth cycle the newly branched internodes become thinner and shorter due to the slowdown in growth processes. If there is a lack of nutrients and water stress the internodes are only briefly pronounced because of the generally slower metabolism. The length of the internodes is in the range of 1 to 35 centimeters. Have short internodes Gewurztraminer. Green Valtellina. Muscat Ottonel. Pinot Blanc. Pinot gris. Pinot Noir. Sylvaner. St. Laurent. Riesling and Zweigelt, have long internodes Blue Portuguese. Blaufränkisch. Chasselas. Frühroter Veltliner. Müller-Thurgau. Neuburger and Riesling,
