Stolon

Stolons ( runners, singular stolon ) are attachments of plants or animals that exist after its separation as an independent beings. They are used for reproduction and are a sort of auto vegetative propagation.

Stolons in plants

Some plant species develop either above or below ground crawling, prolonged side shoots emanating from the stem base, the rosette of leaves or the root collar. They serve the vegetative ( asexual ) reproduction and spread of the plant and are a form of Blastochorie. To roots and upright growing shoots can develop on the so-called Nodien the foothills: If the connecting rungs die then, arise as independent - albeit genetically identical to the parent plant - plants.

Stolons occur in the strawberry for example.

Tubers of

From stolons also thickening can develop ( the sprout tubers ), which serve as storage capacity with memory substrate for energy-containing sugars. Example is the potato.

Stolons in animals

Some types of Vielborstern multiply by Schizogamie. Here, the reproductive serving reproductives grow as body attachments to an ordinary animal. These are called analogous to the foothills of the plants also as stolons.
