rhizome


rhizome

(rī`zōm) or

rootstock,

fleshy, creeping underground stem by means of which certain plants propagate themselves. Buds that form at the joints produce new shoots. Thus if a rhizome is cut by a cultivating tool it does not die, as would a root, but becomes several plants instead of one, which explains why such weeds as Canada thistle and crabgrass are so hard to eradicate. Ginger, the common iris, trillium, and Solomon's-seal all have rhizomes. True arrowroot is starch from the rhizome of a West Indian plant. See perennialperennial,
any plant that under natural conditions lives for several to many growing seasons, as contrasted to an annual or a biennial. Botanically, the term perennial applies to both woody and herbaceous plants (see stem) and thus includes numerous members of the kingdom.

rhizome

a concept developed by Gilles DELEUZE and Félix GUATTARI in Rhizome: an Introduction (1976). At its simplest, the rhizome indicates a means of thinking other than in conventional, ‘arborescent’ ways. Those latter forms are seen to have dominated Western thought, imposing on ‘vertically inclined’ structures which introduce hierarchies and specific, static ‘placings’. In contrast, rhizomic approaches attempt to proceed in other directions, that is, outwards and horizontally avoiding regulation.

Rhizome

 

the underground stem of perennial herbs differing from a root by the presence of small scaly or filmy leaves (that leave scars after dropping off), by the lack of a root cap at the end of the growing part, and, anatomically, by the presence of parenchyma.

Buds form in the nodes or sinuses of the leaves of the rhizome that annually produce new underground shoots and secondary roots. These utilize the nutrients stored in the rhizome. New shoots also form after the death of the aboveground part of the plant as a result of unfavorable conditions (for example, drought) or of crushing or eating by animals. In some plants (orchard grass, timothy), the rhizomes are short and the shoots that form on them above ground grow in a thick bunch. In others (reeds or couch grass), the rhizomes are long, grow rapidly, and branch. After the old parts of the rhizome die off, the underground shoots that have formed on it individuate (that is, vegetative reproduction occurs). The rhizomes in some plants are greatly thickened, tubes forming on them (usually at the ends) that contain primarily carbohydrates. Some rhizomes contain medicinal substances (as in the medicinal valerian), dyes (as in elecampane), or tannins (as in willow grass). Plants with long rhizomes are used to fix sandy soils.

rhizome

a horizontal underground stem (with leaves and buds) that serves as a storage organ and a means of VEGETATIVE PROPAGATION. Rhizomes are found in flowering plants such as Iris.
