The new corm forms at the shoot base just above the old corm. As the new corm grows, short stolons appear that end with the newly growing small cormels. As the plants grow and flower, they use up the old corm, which shrivels away. The new corm that replaces the old corm grows in size, especially after flowering ends.
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 representative CORM that has been extensively characterized both from a biochemical and pharmacological view point is the ruthenium(II) complex RuCl(CO) 3, known as CORM-3. Therapeutic data pertaining to metallic CORMs were reappraised to explore if observed effects are due to CO or if metal reactivity mediates physiological effects via thiol ...
The thin tunic leaves are dry papery, dead sheaths, formed from the leaves produced the year before. They act as a covering that protects the corm from insects and water loss. Internally a corm is mostly made of starch-containing parenchyma cells above a more-or-less circular basal node that grows roots. Corms are sometimes confused with true ...
Corm, modified stems covered by dry scale-like leaves called a tunic, differing from true bulbs by having distinct nodes and internodes; Taproot, the largest, most central, and most dominant root of some plants
Stolons growing from nodes from a corm of Crocosmia. 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.
Corm: A short enlarged underground storage stem, e.g. taro, crocus, gladiolus. Decumbent stem in Cucurbita maxima. Decumbent: A stem that lies flat on the ground and turns upwards at the ends. Fruticose: Stems that grow shrublike with woody like habit. Herbaceous: Non woody stems which die at the end of the growing season.
corm. adj. cormose, cormous. A fleshy, swollen stem base, usually underground and functioning in the storage of food reserves, with buds naked or covered by very thin scales; a type of rootstock. cormel A small corm (or cormlet), forming at the base of a growing larger corm. [30] corneous Horny in texture; stiff and hard, but somewhat tough ...
