10 August 2026
The Piku 4 rootstock was obtained by crossing sour cherry (cultivar Schattenmorelle) with a hybrid combination of Prunus kurilensis and Prunus sargentii. It belongs to the Pillnitz rootstock series for stone fruits and was developed for intensive orcharding.
Trees grafted on this rootstock demonstrate moderate vigor, reducing it by 40–65% compared to wild cherry seedlings. Piku 4 is well-adapted to light sandy soils and is capable of tolerating conditions of insufficient moisture without additional irrigation.
The use of this rootstock promotes early entry of grafted cultivars into bearing and ensures high yields. Plants on this rootstock possess good regeneration ability and resistance to a number of stress factors.
