(P.Cerasifera x P.spinosa)
Rootstock selected at the University of Pisa. It gives the plant a medium-low vigor and requires very fertile and irrigated soils. In these conditions, as a dwarf rootstock, it induces good productivity and very good fruit quality. Good affinity with the main cultivars. It has polloniferous activity, but lower than other plums. It can also adapt well to medium rich soils, as long as it has sufficient water availability and is not heavy with clay. It resists root asphyxia and active limestone well.
