where this is mentioned in the description.
For Prunus domestica, both seedling rootstocks, characterized by high vigor, and clonal rootstocks, which allow for the creation of intensive orchards with regulated growth, are used. Clonal forms are often obtained through interspecific hybridization, which ensures a compact canopy and early onset of fruit bearing.
A critical factor for plum is compatibility with the rootstock, the failure of which often manifests as a fracture at the graft union. Unlike seedling rootstocks, clonal plum forms often allow for deep planting of the root collar, which promotes root system development, but they require strict control of the viral status of the starting material.
