Term (also grafting, copulation, variegated pelting) for the artificial, vegetative propagation of woody plants. This is most common with rose and fruit varieties. In principle, it is a transplantation of a plant part (scion) onto the root part of another plant (rootstock). The process can also be called cloning, because it produces genetically completely identical new plants from the original plants. This technique was already known in antiquity, especially for fruit and olive varieties, and is also mentioned by Cato the Elder (234-149 BC) for vines. The main aim is to preserve special characteristics, especially of fruit-bearing original varieties but also ornamental plants, if their preservation is endangered by poor or disease-prone root systems, unsatisfactory growth vigour (too strong, too weak) or incompatibility with the soil (e.g. lime).
