In mycology, a stolon is defined as an occasionally septate hypha, which connects sporangiophores together. Root-like structures called rhizoids may appear on the stolon as well, anchoring the hyphae to the substrate. The stolon is commonly found in bread molds, and are seen as horizontally expanding across the mold.
Among the flukes belonging to class Digenea, there are two suckers, namely an oral sucker and a ventral sucker (often called acetabulum). [7] The oral sucker is at the tip of the anterior body and directly surrounds the mouth. The ventral sucker is located halfway to the middle of the body on the ventral side.
In botany, a root sprout or sucker is a severable plant that grows not from a seed but from the meristem of a root at the base of or a certain distance from the original tree or shrub. Root sprouts may emerge a substantial distance from the base of the originating plant, are a form of vegetative dispersal , and may form a patch that constitutes ...
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.
Stolon: A horizontal stem that produces rooted plantlets at its nodes and ends, forming near the surface of the ground. 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.
Underground stems are modified plant parts that derive from stem tissue but exist under the soil surface. [1] They function as storage tissues for food and nutrients, facilitate the propagation of new clones, and aid in perennation (survival from one growing season to the next). [2]
The stolon elongates during long days with the presence of high auxins levels that prevent root growth off of the stolon. Before new tuber formation begins, the stolon must be a certain age. The enzyme lipoxygenase makes a hormone, jasmonic acid, which is involved in the control of potato tuber development. [citation needed]
Cultivars grown in the Pacific regions produce good quality corms, as a result of selecting for corm quality and yield. However, the genetic bases of these cultivars is very narrow. Asian cultivars have agriculturally undesirable traits (such as suckers and stolon), but appear to be more genetically diverse.
