Hi Adam,
In Canarias, AG researchers managed to graft Mamey (Pouteria sapota) onto Lucuma (Pouteria obovata),
but they COULD NOT graft onto Canistel (Pouteria campechiana), according to Felipe.
Now, regarding Annonas, there are several combinations that work but MANY that do not. For
instance, a friend o mine managed to graft Rollinia/Annona mucosa onto cherimoya but the scions would not grow.
