Grafted fruit trees

In plant grafting, the success rate is generally highest within the same genus, lower within different genera of the same family, and lowest between different families. Here are some examples to illustrate this: 1. **Grafting within the same genus**: - **Malus (Apple genus)**: Grafting different species of apple trees, such as the domestic apple (Malus domestica) and the wild apple (Malus sieversii), is usually very successful because they belong to the same genus. - **Citrus (Citrus genus)**: Grafting an orange (Citrus sinensis) and a lemon (Citrus limon) is also typically successful since they are both part of the Citrus genus. 2. **Grafting within the same family but different genera**: - **Rosaceae (Rose family)**: Grafting an apple tree (Malus domestica) and a pear tree (Pyrus communis) can be done since they are both in the Rosaceae family. However, the success rate is lower compared to grafting within the same genus because apples and pears belong to different genera (Ma
