Pome (accessory fruit of the Rosaceae family)

A pome is an accessory fruit produced by plants in the Malinae subtribe of Rosaceae; the true seeds lie in a central core and the edible flesh is formed from floral tissues. Examples: apples and pears.

Overview

A pome is a botanical fruit type produced by members of the subtribe Malinae within the Rosaceae family. Pomaceous fruits are familiar in everyday diets because they include commonly cultivated trees such as apples and pears. What distinguishes a pome is that the juicy, edible portion is not derived solely from the ovary but from surrounding floral tissues.

Structure and characteristics

In a pome the true carpels (the ovary) form a central, usually firm core that contains the seeds. The bulk of the fruit—the sweet, firm flesh consumers eat—is accessory tissue, often arising from the hypanthium or floral tube and other supporting parts. Pomes typically have a few carpels united in the center and a skin that can be smooth or textured. Their texture, sugar content and acidity vary widely between species and cultivars.

Botanical classification

Pomaceous fruits are characteristic of plants classified in the Malinae subgroup, part of the tribe Maleae in the subfamily Amygdaloideae of the family Rosaceae. Common genera that produce pomes include Malus (apples), Pyrus (pears), Cydonia (quince) and Mespilus (medlar).

Examples and uses

Apples are eaten fresh, cooked, processed into juice and cider, and valued for pectin.
Pears are consumed fresh, canned, or used in culinary preparations and preserves.
Other pomes such as quince and medlar are used for jams, jellies and traditional recipes.

History and significance

Pomaceous fruits have been cultivated for millennia across temperate regions. Domestication and selective breeding produced the wide variety of sizes, flavors and storage qualities seen today. Apples and pears have cultural, economic and nutritional importance in many societies and are central to fruit agriculture in numerous countries.

Distinctions and notable facts

Unlike drupes (stone fruits) or true berries, pomes are accessory fruits: the edible flesh is mainly from non-ovarian tissue while the central core contains the seeds. This structural difference influences how pomes are processed and stored, and explains why their flesh often has a distinct texture compared with other fruit types.
