In the ‘Piano Noce’ forest nursery, the clonal orchard was set up with the aim of conserving the A. nebrodensis population’s germplasm and promoting the production of improved seed in the future, since the grafted plants grow close one another and are able to crossbreed when they reach fertility. All 30 trees of the natural population are represented in the orchard, propagated by grafting, following an optimized protocol.
