Vigor and Training Height of Grapevines

Vitis vinifera L.

For grapevines, the concept of 'bush height' as a varietal trait does not exist, as the habitus is determined by the training system. In agronomy, a distinction is made between biological shoot vigor and technical trunk height.

In the reference 29 varieties crop Common grape vine, where this is mentioned in the description.

In ampelography, grapevine vigor is assessed through indicators of the average length and number of annual shoots per vine, which is an inherited varietal trait and correlates with the capacity of the root system. Vigorous varieties require larger feeding areas, long pruning, and specific bud loads.

Training height is an agrotechnical decision that depends on climatic conditions, the type of training, and the level of mechanization. Low training systems with a trunk height of 20–60 cm are more susceptible to the risk of spring frosts, whereas high training systems exceeding 120 cm improve vine aeration and reduce the infectious background.
