Variety traits

Blueberry vigor

Vaccinium corymbosum L.

Highbush blueberry vigor characterizes the intensity of vegetative plant development, expressed in bush volume and the length of annual shoots. This trait is a determining factor in selecting planting patterns, pruning, and balancing vegetation with fruit production.

In the reference 41 varieties crop Highbush blueberry, where this is mentioned in the description.

According to international UPOV guidelines (TG/137/5), the vigor of blueberries is assessed by experts visually on a nine-point scale, where 1 corresponds to very weak and 9 to very strong development intensity. Auxiliary quantitative indicators include total bush height in meters and the average length of annual shoots in centimeters.

This trait directly influences the crop's agrotechnics. Highly vigorous varieties require greater spacing between bushes and more intensive pruning to prevent overcrowding and shading of the canopy. For varieties with high growth energy, it is necessary to manage nitrogen nutrition to maintain a balance between vegetative mass accumulation and yield quality, as excessive growth can reduce berry size and taste characteristics.
