Stephen,
I have an elderly friend who's been working at identifying and collecting superior timber-type black walnuts across the Southeastern US for 30 years or so, and while it's been mostly anecdotal observation on his part, it seems that for that species - or at least the populations within that species that he's worked with - that there is a significant problem with 'loss of juvenile traits' - particularly the desirable rapid, upright growth habit - when topworking scions from an older mature tree onto seedling rootstocks. It either requires additional pruning/training to get a good clean bole that would yield a good sawlog or perhaps cutting back multiple times to induce rapid sucker-like growth that may revert back to a more juvenile, vegetative style of growth.
