  2. Tuber - Wikipedia

    en.wikipedia.org/wiki/Tuber

    In stem tubers the order is reversed, with the distal end producing stems. Tuberous roots are biennial in duration: the plant produces tubers the first year, and at the end of the growing season, the shoots often die, leaving the newly generated tubers; the next growing season, the tubers produce new shoots.

  3. Rhizome - Wikipedia

    en.wikipedia.org/wiki/Rhizome

    The rhizome also retains the ability to allow new shoots to grow upwards. [4] A rhizome is the main stem of the plant that runs typically underground and horizontally to the soil surface. [5] [6] Rhizomes have nodes and internodes and auxiliary buds. [7] Roots do not have nodes and internodes and have a root cap terminating their ends. [8]

  4. Ornamental bulbous plant - Wikipedia

    en.wikipedia.org/wiki/Ornamental_bulbous_plant

    Such tubers tend to form at the sides of the parent plant and are most often located near the soil surface. A below ground stem tuber is normally a short-lived storage and regenerative organ developing from a shoot that branches off a mature plant. The new tubers are attached to a parent tuber or form at the end of an underground rhizome.

  5. Underground stem - Wikipedia

    en.wikipedia.org/wiki/Underground_stem

    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.

  6. Corydalis pumila - Wikipedia

    en.wikipedia.org/wiki/Corydalis_pumila

    The old tuber, meanwhile, withers quickly, remaining for a short time in the form of coverings enveloping the daughter tuber. At the time of flowering, the roots growing from the old tuber also die off, and in September–October a new root system develops from the new tuber. Very rarely, two daughter tubers develop in place of one tuber.

  7. Vegetative reproduction - Wikipedia

    en.wikipedia.org/wiki/Vegetative_reproduction

    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 ...

  9. Corm - Wikipedia

    en.wikipedia.org/wiki/Corm

    Those growing from the bottom of the corm are normal fibrous roots formed as the shoots grow, and are produced from the basal area at the bottom of the corm. The second type are thicker layered roots called contractile roots that form as the new corms are growing. They pull the corm deeper into the soil.
