Plants use underground stems to multiply by asexual reproduction and to survive from one year to the next, usually through dormancy. [11] Some plants produce stems modified to store energy and preserve a location of potential growth to survive a cold or dry period which normally is a period of inactive growth, and when that period is over the ...
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.
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 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 ...
A bulb of Muscari has reproduced vegetatively underground to make two bulbs, each of which produces a flower stem. Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or ...
Thorn: A modified stem with a sharpened point. Tuber: A swollen, underground storage stem adapted for storage and reproduction, e.g. potato. Woody: Hard textured stems with secondary xylem. Sapwood: A woody stem, the layer of secondary phloem that surrounds the heartwood; usually active in fluid transport
“This plant spreads by both rhizome, or underground stems, and seeds,” says Daria McKelvey, supervisor for the Center for Home Gardening Information and Outreach at Missouri Botanical Garden ...
In botany, stolons are plant stems which grow at the soil surface or just below ground that form adventitious roots at the nodes, and new plants from the buds. [1] [2] Stolons are often called runners. Rhizomes, in contrast, are root-like stems that may either grow horizontally at the soil surface or in other orientations underground. [1]
