With grafting it is possible to grow a tree that produces a multitude of fruit varieties including seedless fruits.

How can grafting be used to propagate seedless fruits. A slip small slip of bark or a bud is taken from the desired tree and grafted onto the rootstock of a young compatible sapling. This technique is most notably used with fruit trees in which a branch from one tree is cut and attached to another fruit tree. Seedless fruit such as navel oranges are propagated asexually usually by grafting.

Grafting is the main method used to propagate fruit trees. Grafting allows a single tree to grow many different types of fruits some of which can be special seedless varieties. Scientists who study genetics are always looking to push the envelope when it comes to new varieties of seedless fruits.

The most frequent reasons for lack of seed development are pollination failure or nonfunctional eggs or sperm. If done at the right time of year when sap is running high the graft will easily take growing onto the parent tree and using that tree as a source of nutrition.
