Root mass and root distribution of ‘Edinburg’ plum trees, grafted on clonal rootstock VVA-1 (hybrid of Prunus tomentosaand P. cerasifera), rooted stem cuttings of Prunus tomentosa, and seedlings of P. cerasifera, were studied to the depth of one meter in sod-podzolic soil. Trees on VVA-1 and P. tomentosarootstocks were 1.5 to 3 times smaller than on P. cerasifera. The root system of P. tomentosawas very weak. Specific mass of fibrous roots of VVA-1 was twice that of P. cerasifera. Yield efficiency of ‘Edinburg’ trees on rootstock VVA-1 was twice that of trees on P. cerasifera.
