Cultivation
Vitis vinifera L.
A scion is the varietal part of the Vitis vinifera grapevine that provides the quality characteristics of the yield and is grafted onto a resistant rootstock to protect against phylloxera and adapt to soil conditions.
In the reference 5 varieties crop Common grape vine, where this is mentioned in the description.
In viticulture, the scion is the carrier of varietal berry traits, including taste, size, and technological parameters. The main objective of grafting it onto a rootstock of American origin is to ensure the resistance of European varieties to root phylloxera, as well as to provide adaptation to specific soils, such as high-carbonate sites, or to control the vine's vigor and ripening period.
The success of forming a grafted grapevine seedling depends critically on affinity—the anatomical and physiological compatibility of a specific combination. The process requires precise alignment of cambial layers to form callus tissue, which facilitates the transition of vascular bundles from the rootstock to the scion, necessitating strict adherence to the stratification regimen.
