Branching — Common Hazel

Corylus avellana L.

Branching of common hazel, or branching density, is a key morphological trait for variety identification and crown architecture assessment.

In the reference 3 varieties crop Common hazel, where this is mentioned in the description.

To evaluate branching density, a nine-point scale is used, where 1 point corresponds to a very sparse crown, 5 points to a medium, and 9 points to a very dense one. In addition to visual observation, terrestrial laser scanning technologies are employed for objective analysis, allowing for the creation of three-dimensional tree models.

The trait exhibits pronounced varietal specificity: low density is characteristic of the Butler and Tonda Gentile Romana varieties, medium density for Fertile de Coutard and Tonda di Giffoni, and high density for Bergeri, Cosford, and Ennis. This indicator directly affects productivity, the need for crown thinning, and the prevention of fungal diseases.
