1. Is it true that P. betulifolia is a better (dwarf) rootstock for Asian 
pear (P. serotina) then the OHxF series?  I'm confused because a certain 
nursery says its the choice rootstock for Asian pears; but then they have 
options for Asian pear on both P. betulifolia and, alternately, the same 
varieties (in some cases) also on an OHxF roostock.  Why would anyone want to 
choose an Asian pear to be grafted on an OHxF if it supposedly the case that 
the rootstock of choice is P. betulifolia?


2. What rootstock should be used if multi-grafting a pear so that the frame 
(above the roostock) is European pear (P. communis) and the top portion of 
the limbs are varieties of Asian pear?  The OHxF series in this case?


The conditions:
Well-drained soil; irrigation available; small space - needs to be dwarfing 
to around 15 to 20' if unmanaged.
