Maybe this should be a new subject at some point. Roots-studies have
shown that the top can be affected by rootstock selection as in apple
and many other fruit trees, so there can be an interaction. Research
with red oak has shown no affect from the rootstock on early acorn
bearing and growth rate, the traits were genetic attributes of the top
(scion). Old Japanese tree lilacs are probably all seed produced
since the first cultivar was introduced in the 1970's I believe.
Seedling rootstocks do provide an earlier heavier root system for
faster growth under nursery conditions. My experience with tree
lilacs is that the top maintains its genetic attributes when grafted
(budded) on seedling rootstocks and this is the commonly used method
to perpetuate those cultivars. I maintain some Japanese tree lilacs
for rootstocks of Japanese tree and Pekin lilac selections I want to
graft.
The English walnut cultivars on the west coast were grafted on black
walnut as one of rootstocks in orchard production. There is much to
be learned on the rootstock/scion interaction and the rootstock
interaction with the factor most people never consider, the incredible
complexity of soils and soil microorganisms.
