Definition of stolon in US English:



  • 1Botany
    A creeping horizontal plant stem or runner that takes root at points along its length to form new plants.

    • ‘Any horizontal stolon growing from the ramet was removed.’
    • ‘Others spread aggressively by stolons (stems that creep along the soil surface, taking root and forming new plants at intervals).’
    • ‘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.’
    • ‘Perennial weeds set fewer seeds, but sustain and propagate themselves other ways, with creeping stolons, rhizomes, bulbs or other plant parts.’
    • ‘Clonal progeny may be produced by stolons, runners, rhizomes, tubers, buds on bulbs, corms and roots, layering of stems, and agamospermous seed.’

    1. 1.1 An arching stem of a plant that roots at the tip to form a new plant, as in the bramble.
      • ‘Within this species the number of viable seeds per rosette, the importance of clonal reproduction by stolons and stolon length are highly variable.’
      • ‘Older studies noted that runners, stolons or prostrate stems of many plants became more erect when shaded.’
      • ‘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.’
      • ‘In late spring, the parent plants send out chicks often on long colourful stems called stolons that form dense carpets.’
  • 2Zoology
    The branched stemlike structure of some colonial hydroid coelenterates, attaching the colony to the substrate.

    • ‘Well-studied examples occur in the hydractiniid hydroids, which encrust hard substrata with stolons that serve as tube-like connections between feeding polyps.’
    • ‘When two or more larvae recruit to the same substratum, stolons of different colonies may eventually come into contact.’
    • ‘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.’
    • ‘In Hydractinia, these features involve changes in the regulation of axial patterning along stolons and polyps.’


Early 17th century: from Latin stolo, stolon- ‘shoot, scion’.
