What it is Filled

A structural axis of a vascular plant, whether main or lateral, that bears leaves, buds and flowers and conducts water, nutrients and sugars, either herbaceous or woody; modified stems include rhizomes such as galangal, tubers, stolons, corms and caudices.

Why it exists Filled

Let an agent explain plant stems by structure, function, types and modifications, and support gardening, propagation and plant identification.

Distinguishing features Filled

  • Bears leaves and buds
  • Has nodes and internodes
  • Conducts water and sugars
  • Can store food

What robots and AI may and may not do Filled

Must not

  • Cut or damage stems of protected or wild plants without authority.
  • Identify stems or tubers as edible without certainty.
  • Move plant material across borders against plant health rules.

Only with a human decision

  • Harvesting rhizomes or tubers from wild populations.

May

  • Identify and describe plant stems and their modified forms.
  • Report stem damage, disease or pests to growers.

Moral aspects Filled

  • Misidentifying edible stems and tubers can poison people.
  • Wild plants and their habitats can be harmed by careless harvesting.

Who is affected

  • Foragers and eaters
  • Growers
  • Wild plant populations

Owners Filled

Steward

The owner of the land or crop; nature authorities for protected species.

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.plant-stem
  • Wikidata: Q134267 (https://www.wikidata.org/wiki/Q134267)

Direct properties required Filled

  • Stem length: metres - Measure along the stem axis between specified endpoints because dimensions vary widely with species and growth stage.
  • Stem diameter: millimetres - Measure across the stem at a recorded position and record multiple widths when the cross section is irregular.
  • Fresh mass: grams - Weigh a defined stem sample before drying and record its sampling boundaries and hydration condition.

Recognition required Filled

  • Nodes and buds
  • Rhizomes and tubers as underground stems
  • Roots lack nodes and leaves
  • Green or woody axes with nodes, internodes, buds and leaves.

Capabilities and actions required Filled

  • identify stem types and modifications
  • explain xylem and phloem transport
  • propagate plants from stem cuttings
  • recognise stem problems in plants

Hazards and failure modes required Filled

  • Stem rots and diseases
  • Spreading invasive plants from stem fragments
  • Sap irritation from some species

Standards and interfaces required Filled

  • Plant health rules for moving plant material

Context of use required Filled

  • Support, transport and storage in plants.
  • herbaceous stems
  • woody stems
  • rhizomes and stolons
  • tubers and corms
  • tillers and caudices

Sources Filled

  1. Wikidata item Q134267: plant stem - identity and sense of the item
  2. Wikipedia: Plant stem - general description of the item

Open questions

  • Should stem modifications be separate entries?
  • How should botanical glossaries be linked?
  • How should invasive species be linked?
