Graft affinity

Term used in viticulture to describe the compatibility (actually kinship, attraction) of graft (above-ground shoot) and rootstock (rootstock) when grafting vines. The closer the "kinship" of the two parts, the more likely it is that a good affinity exists. The causes of lower or higher affinity also lie in different morphology, the wood body structure and lower or higher market shares of the two partners. A good affinity causes a good growing together of the two parts and therefore a satisfactory yield. See also the keywords adaptation, molecular genetics and vineyard care.
