Freshly dug sweet potato plants with tubers Hemerocallis tuber roots. A root tuber, tuberous root or storage root is a modified lateral root, enlarged to function as a storage organ. The enlarged area of the tuber can be produced at the end or middle of a root or involve the entire root.
Tubers develop from either the stem or the root. Stem tubers grow from rhizomes or runners that swell from storing nutrients while root tubers propagate from roots that are modified to store nutrients and get too large and produce a new plant. [22] Examples of stem tubers are potatoes and yams and examples of root tubers are sweet potatoes and ...
Its root can attain lengths up to 2 m (6 + 1 ⁄ 2 ft) and weigh up to 20 kilograms (44 pounds). The heaviest jícama root ever recorded weighed 23 kg (51 lb) and was found in 2010 in the Philippines. [4] Jícama is frost-tender and requires nine months without frost for a good harvest of large tubers or to grow it commercially.
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. [10] In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to plants with rhizomes.
Staple foods are derived from either plant or animal products that are digestible by humans and can be supplied in substantial quantities. Common plant-based staples include cereals (e.g. rice, wheat, maize, millet, barley, oats, rye, spelt, emmer, triticale and sorghum), starchy tubers (e.g. potato, sweet potato, yam and taro) or root vegetables (e.g. cassava, turnip, carrot, rutabagas), and ...
