It is unlikely that you would be able to plant the shoot and have it survive. There would need to be at least a small portion of roots attached for that to work. If the shoot was growing off of a root for example the shoot had some roots of it's own, then you would have a good chance. In the case of a hybrid bradord pear, the root system is not the same as the top and you could end up with a fruiting pear or some other graft compatable tree.
