Rootstock — hybrids between Prunus davidiana and Prunus persica

hybrids between Prunus davidiana and Prunus persica

The use of peach and Prunus davidiana hybrids as rootstocks is associated with specific biochemical incompatibility reactions and limited resistance to soil-borne pathogens.

In the reference 6 varieties crop hybrids between Prunus davidiana and Prunus persica, where this is mentioned in the description.

Grafting commercial cultivars onto P. persica × P. davidiana hybrid rootstocks is characterized by a process of translocation incompatibility. In the graft union zone, an abnormal accumulation of phenolic compounds is observed: flavonols in the 'Cadaman' rootstock and flavanones in the 'Barrier' rootstock, which distinguishes them from fully compatible combinations.

These rootstocks are used to increase resistance to specific pests, such as root-knot nematodes, but they possess a number of physiological limitations. Specifically, the 'Nemaguard' rootstock demonstrates sensitivity to waterlogging, calcareous soils, Verticillium wilt, and bacterial canker, while 'Cadaman' exhibits low resistance to Phytophthora.
