An antique spurge plant, Euphorbia antiquorum, sending out white rhizomes. In botany and dendrology, a rhizome (/ ˈ r aɪ z oʊ m / RY-zohm) [note 1] is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. [3] Rhizomes develop from axillary buds and ...
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.
Zingiberaceae (/ ˌ z ɪ n dʒ ɪ b ɪ ˈ r eɪ s i. iː /) or the ginger family is a family of flowering plants made up of about 50 genera with a total of about 1600 known species [4] of aromatic perennial herbs with creeping horizontal or tuberous rhizomes distributed throughout tropical Africa, Asia, and the Americas.
Rhizobacteria are root-associated bacteria that can have a detrimental (parasitic varieties), neutral or beneficial effect on plant growth. The name comes from the Greek rhiza, meaning root. The term usually refers to bacteria that form symbiotic relationships with many plants . Rhizobacteria are often referred to as plant growth-promoting ...
As an example of an intermediate, the tuber of Cyclamen arises from the stem of the seedling, which forms the junction of the roots and stem of the mature plant. In some species (e.g. Cyclamen coum ) roots come from the bottom of the tuber, suggesting that it is a stem tuber; in others (e.g. Cyclamen hederifolium ) roots come largely from the ...
Typically after the formation of the new plant the stolon dies away [6] in a year or two, while rhizomes persist normally for many years or for the life of the plant, adding more length each year to the ends with active growth. The horizontal growth of stolons results from the interplay of different hormones produced at the growing point and ...
In certain algae, there is an extensive rhizoidal system that allows the alga to anchor itself to a sandy substrate from which it can absorb nutrients. [3] Microscopic free-floating species, however, do not have rhizoids at all.
The rhizome of some species, including Atractylodes lancea, and A. macrocephala (Chinese: 白朮), are used in traditional Chinese medicine, and in Japanese medicine, [6] as a diuretic, an anti-inflammatory, an anti-coagulant, together with other uses.
