OTHER INFORMATION

Behavior in the nursery: it shows a moderate vegetative resumption, a good development of the root system, with a prevalence of fleshy roots. In the nursery it guarantees high yields.

Behavior in the propagation block: it tends to early lignification; it is suitable to being raised sprawling on the ground: however, it guarantees medium to high yields with both breeding systems.

Behavior in the open field: it induces excellent vigor thus ensuring high yields; it is suitable to clayey-calcareous, compact soils, as well as to soils rich in skeleton and not very fertile.
