Grafting is a horticultural technique that involves joining two different plants together so that they grow as one. The top part of the plant, known as the scion, is joined to the bottom part, known as the rootstock, which provides the plant with nutrients and water.
Apple trees (Malus spp.) and loquat trees (Eriobotrya japonica) are from different plant families, so grafting them together is not a natural combination. While grafting can sometimes create new and interesting plant varieties, it is unlikely that grafting an apple onto a loquat will result in a healthy and productive tree.
Furthermore, the size and growth habits of the two species are very different, so grafting them together may result in an unstable and unbalanced tree that is prone to disease and pest problems.
Grafting apple with loquat is possible, but it is not a commonly practiced grafting combination because these two plants are not closely related. Apple belongs to the Rosaceae family, while loquat belongs to the Rosaceae subfamily Maloideae.
Grafting involves joining the vascular tissues of two plants to create a single plant. To graft apple with loquat, you will need to carefully match the cambium layer of the apple and loquat stems, then bind the two together until they heal into a single plant. However, because apple and loquat are not closely related, the grafting success rate may be low, and the resulting plant may not grow well or produce fruit.
If you are interested in grafting fruit trees, it is recommended to stick with closely related species within the same genus or subfamily to increase the chances of success. For example, apples can be grafted with other apple varieties, and loquats can be grafted with other fruit trees in the Maloideae subfamily, such as pears and quinces.
