Definition of stolon in English: stolonnoun ˈstəʊlɒnˈstoʊlən 1Botany A creeping horizontal plant stem or runner that takes root at points along its length to form new plants. 〔植〕匍匐茎 Example sentencesExamples - Clonal progeny may be produced by stolons, runners, rhizomes, tubers, buds on bulbs, corms and roots, layering of stems, and agamospermous seed.
- Perennial weeds set fewer seeds, but sustain and propagate themselves other ways, with creeping stolons, rhizomes, bulbs or other plant parts.
- The length of the lateral shoot at each phytomer position along the primary stolon of plants after 45 (solid symbols) and 38 (open symbols) d growth.
- Others spread aggressively by stolons (stems that creep along the soil surface, taking root and forming new plants at intervals).
- Any horizontal stolon growing from the ramet was removed.
Synonyms shoot, offshoot, sprout, tendril, sprig, sucker - 1.1 An arching stem of a plant that roots at the tip to form a new plant, as in the bramble.
生殖根 Example sentencesExamples - In late spring, the parent plants send out chicks often on long colourful stems called stolons that form dense carpets.
- Within this species the number of viable seeds per rosette, the importance of clonal reproduction by stolons and stolon length are highly variable.
- Leaves communicate photoperiodic signals to meristems, stolons and buds in flowering, tuberization and dormancy.
- The experimental plants were partitioned into roots, petioles, leaves and stolons.
- Older studies noted that runners, stolons or prostrate stems of many plants became more erect when shaded.
2Zoology The branched stemlike structure of some colonial hydroid coelenterates, attaching the colony to the substrate. 〔动〕匍匐水螅根 Example sentencesExamples - In Hydractinia, these features involve changes in the regulation of axial patterning along stolons and polyps.
- Well-studied examples occur in the hydractiniid hydroids, which encrust hard substrata with stolons that serve as tube-like connections between feeding polyps.
- The base of the polyp becomes fixed to the substrate and stolons emanate from the aboral pole of the primary polyp.
- Colonies are diploblastic and composed of three morphological structures: polyps, stolons and the stolonal mat.
- When two or more larvae recruit to the same substratum, stolons of different colonies may eventually come into contact.
OriginEarly 17th century: from Latin stolo, stolon- 'shoot, scion'.
