Term (also grafting, copulation, variegated furs) for the artificial, vegetative reproduction of lignifying plants. This is most common in rose and fruit varieties. In principle, it is a transplantation of a plant part(graft) onto the root part of another plant(rootstock). The process can also be called cloning, because in this way 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 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 of ornamental plants, if their preservation is endangered by poor or disease-prone root systems, unsatisfactory growth strength (too strong, too weak) or incompatibility with the soil (e.g. lime).
