Examples of plants that are propagated this way include hops, asparagus, ginger, irises, lily of the valley, cannas, and sympodial orchids. Stored rhizomes are subject to bacterial and fungal infections , making them unsuitable for replanting and greatly diminishing stocks.
These stolon-like rhizomes are long and thin, with long internodes and indeterminate growth with lateral buds at the node, which mostly remain dormant. [ citation needed ] In potatoes , the stolons [ 15 ] start to grow within 10 days of plants emerging above ground, with tubers usually beginning to form on the end of the stolons. [ 16 ]
Stem tubers manifest as thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); examples include the potato and yam. The term root tuber describes modified lateral roots , as in sweet potatoes , cassava , and dahlias .
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 rhizome is a horizontal stem that often grows underground, usually sending out roots and shoots from its nodes. Some plants have rhizomes that grow above ground or that lie at the soil surface, including some Iris species. Usually, rhizomes have short internodes; they send out roots from the bottom of the nodes and new upward-growing shoots ...
A rhizome is a modified underground stem serving as an organ of vegetative reproduction; the growing tips of the rhizome can separate as new plants, e.g., polypody, iris, couch grass and nettles. Prostrate aerial stems, called runners or stolons , are important vegetative reproduction organs in some species, such as the strawberry , numerous ...
Rhizome: A horizontal underground stem that functions mainly in reproduction but also in storage, e.g. most ferns, iris. Runner: A type of stolon, horizontally growing on top of the ground and rooting at the nodes, aids in reproduction. e.g. garden strawberry, Chlorophytum comosum.
Jointed; separating freely, leaving a clean scar; e.g. the frond s of certain ferns where they join the rhizome. ascending 1. (of a stem) Spreading horizontally, then directed upward; an ascending stem is more or less prostrate near its base, then erect. 2. (of an ovule) Attached somewhat above the base. ascidiate
