Grafting "fruit stem" onto rootstock
I know this is an odd question, but I have been discussing the probability of this succeeding with a friend, and we decided to turn to the forum for another perspective.
My friend wants to attempt to graft 1-3" long-ish sections of "fruit stem" from an asian pear onto pear or quince rootstock that he has.
These fruit stem sections do not have leaves, nor a terminal bud, and they are generally greenish although some might be slightly more brown-ish and hardwood like.
Any thoughts as to methods he could use to propagate them? (Not just grafting).
He does not have any possible way to obtain proper scionwood sections.
Is grafting feasible? Best type of graft to attempt and conditions?
Thanks for the input!
