The pear may be made to grow for a time when grafted on the apple, but it is usually impossible to graft the pear species permanently on the apple species with any degree of success; yet pears thrive on quinces and also on hawthorns, which are well-marked genera. In nursery practice when pear stocks are not at hand, long pear cions may be worked on apple pieces and roots may form from the cion and the pear become own-rooted on the failure of the apple stock. Apples appear not to be successful on pears.
