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 ...
This is a process known as vegetative reproduction and is used by farmers and gardeners to propagate certain plants. This also allows for lateral spread of grasses like bamboo and bunch grasses. Examples of plants that are propagated this way include hops, asparagus, ginger, irises, lily of the valley, cannas, and sympodial orchids.
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 ...
Taro corms for sale in a Réunion market. Corm, bulbo-tuber, or bulbotuber is a short, vertical, swollen underground plant stem that serves as a storage organ that some plants use to survive winter or other adverse conditions such as summer drought and heat (perennation).
Tubers help plants perennate (survive winter or dry months), provide energy and nutrients, and are a means of asexual reproduction. [1] Stem tubers manifest as thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); examples include the potato and yam.
Clonal colonies are common in many plant species. Although many plants reproduce sexually through the production of seed, reproduction occurs by underground stolons or rhizomes in some plants. Above ground, these plants most often appear to be distinct individuals, but underground they remain interconnected and are all clones of the same plant.
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]
Several types of ephemeral plants exist. The first, spring ephemeral, refers to plants that emerge quickly in the spring and die back to their underground parts after a short growth and reproduction phase. Desert ephemerals are plants which are adapted to take advantage of the short wet periods in arid climates.
