Pome: "Botany. The type of fruit that is characteristic of the apple (Malus domestica), the pear (Pyrus communis), and related members of the family Rosaceae, which consists of a fleshy, enlarged receptacle enclosing a tough central core (the true fruit), formed from several united carpels and containing the seeds." Outside of botany, that usage is obsolete.
The definition of pomology is broader, however: "The branch of horticulture concerned with the cultivation of fruit."
