Anyone who follwed the mild debate here about the affects of summer pruning should be interested to know that the research by D. Ferree Lee referred to was likely done with dwarfing rootstocks.  I couldn't find that piece of info on-line but Lee thinks this is the case.

 

I don't believe that any pruning research done with dwarfing rootstock could be presumed to apply to more vigorous trees- Lee respectfully disaggrees.  You can draw you own conclustions.
