Definition of stolon in English:

stolon

noun 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. 1.1 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.

Derivatives

  • stolonate

  • adjectiveˈstəʊlɒneɪt

      • B. erecta is a stoloniferous species, consisting of a rosette of petiolated dissected leaves.
      • The species is sometimes stoloniferous, with a rosette of basal leaves and a variable number of fertile stems bearing dichasium-type inflorescences.
      • Other studies have noted changes in resource allocation with reference to the availability of supports as well as rates of development, leaves, stoloniferous axes and other climbing aids.
