Term (also grafting, copulation, variegated furs) 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 referred to as cloning, because genetically completely identical new plants are created from the original plants. This technique was already known in ancient times, especially for fruit and olive varieties, and is mentioned by Cato the Elder (234-149 BC) for vines as well. The main goal is the preservation of special characteristics, especially of fruit-bearing original varieties but also ornamental plants, if their preservation is endangered by poor or disease-susceptible root system, unsatisfactory growth vigour (too strong, too weak) or incompatibility with the soil (e.g. lime).
