Title: Root System of Plum Trees on Standard and Dwarfing Rootstocks
Author: A.S. Devyatov
Abstract:
Root mass and root distribution of 'Edinburg'
plum trees, grafted on clonal rootstock VVA-1
(hybrid of Prunus tomentosa and 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. tomentosa rootstocks were 1.5
to 3 times smaller than on P. cerasifera. The root
system of P. tomentosa was 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.
