Title: A Resolution of the American Pomological Society on the Labeling of Nursery Stock
Author: APS Citation
Abstract:
"Whereas the success of a fruit tree
in a particular situation, be it in a
commercial orchard or home garden,
depends greatly upon the type of
rootstock and/or interstock employed
in the make-up of that tree; and,
"Whereas most fruit trees sold are
not fully labeled in this way, be it
resolved that the American Pomological
Society recommend that all labels
attached to fruit trees offered for sale
identify not only the scion variety, but
also the rootstock and/or interstock
that may be employed;
"Be it further resolved that a copy
of this resolution be sent to all State
Horticultural Societies, Fruit Growers'
Associations ,and Nursery Associations
for publicizing among their membership
and that this resolution be otherwise
given as wide publicity as possible
to stimulate maximum interest in
the adoption of this urgently needed
improvement in labeling practice."
DefinitionsRootstock (understock): That, part of
a budded or grafted tree which provides
the root system.
Seedling rootstock: A rootstock produced
from seed.
Clonal rootstock: A rootstock propagated
by a vegetative or asexual
method, such as the rooting of stem
cuttings taken from the stock plant
or single original plant of a named
scion or rootstock variety.
lnterstock (intergraft, stem-piece, interstem):
That portion of the trunk
of a tree which had been grafted
on to a rootstock, and upon which
the scion variety has later been grafted or budded.
This propagation
technique, which is sometimes
referred to as "double-working", results
in a three-component tree.
Labelling: The names of the various
components of the tree should be'
separated by a diagonal bar (/) and
arranged in order from scion variety
to rootstock.
For example, McIntosh/EM IX; McIntosh/Virginia
Crab / Delicious seedling.
