Vigor — Sour Cherry

Prunus cerasus L.

A biometric indicator characterizing the growth processes of a cultivar through crown volume, its projection area, and trunk cross-section. It is used for selecting scion-rootstock combinations and planning planting schemes in intensive horticulture.

In the reference 97 varieties crop Sour cherry, where this is mentioned in the description.

To objectively assess the vigor of sour cherry (Prunus cerasus), a complex of indicators is used: crown volume, its projection area, and trunk cross-sectional area. When classifying cultivars into low-, medium-, and high-vigor, the consistency of these parameters is taken into account, and their values significantly depend on the rootstock; for example, the use of clonal rootstocks such as VSL-2 allows for a reduction in growth parameters by 30% or more.

The orchard management strategy directly depends on the tree's vigor. Tree-like cultivars can reach a height of 5–10 m, whereas in intensive horticulture, priority is given to low-vigor forms. Vigor control is also achieved through the selection of trunk height and pruning techniques: branch orientation and thinning allow for the regulation of vertical growth and the onset of the fruiting period.
