Haha, this is difficult to answer. Let’s talk about it in two parts:

First, most fruits are grafted in production practice. Propagating saplings in this way can not only ensure the purity of the variety, but also make the fruit trees bloom and bear fruit as soon as possible. When apple pears are cultivated as fruits, grafting is also used. From this point of view, apple pears are grafted.

Secondly, as far as the origin of the apple pear variety is concerned, it was definitely not cultivated through grafting. Because, in theory, grafting will not change the genetic traits of the plant. Therefore, if the sentence "Apple pears are grafted" means that apple pears are formed by grafting apple branches onto pear trees or pear branches onto apple trees, that would be wrong. A pear grafted on an apple tree is still a pear, and a red Fuji grafted on a pear tree is still a red Fuji.
