It usually has a good affinity for grafts. It gives very good results with the Garnacha Tinta .
The vigor it provides is quite high and induces an important vegetative development.
Lot’s Rupestris has a tendency to delay the vegetative cycle and can induce a lack of color in certain sensitive varieties.
