Raphanus sativus
Enable an AI agent to recognise Raphanus sativus, assess its developmental and usable state, and decide which cultivation, harvest, propagation or handling actions are appropriate.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise Raphanus sativus, assess its developmental and usable state, and decide which cultivation, harvest, propagation or handling actions are appropriate.
It can be Identify and document a plant using provenance and stage-appropriate botanical evidence.; Monitor storage-organ growth and inspect a representative harvested sample for internal defects.; Adjust cultivation conditions when plant observations and growing-context evidence support a specific intervention.; Harvest the intended organ when cultivar-specific maturity and condition evidence support doing so.; Retain selected plants for flowering and seed production while tracking possible pollen sources.; Separate damaged or deteriorating harvested organs and route them for further assessment or disposal according to the intended use..
Distinguishing features
Against turnip and other swollen Brassicaceae crops, compare mature fruit structure alongside leaves and flowers; storage-organ colour or roundness alone does not establish Raphanus identity.
Against wild radish and other Raphanus taxa, examine mature pod shape, constrictions and break-up behaviour using a regional identification key; record uncertainty when only vegetative material is available.
Against an assumption that every radish has a round red root, check cultivar provenance and the complete plant: elongated, differently coloured and pod-oriented forms must remain eligible for this entry.
Against horseradish or other pungent roots, require botanical or traceable provenance evidence; pungency and a pale elongated root are insufficient identification tests.

- Processed radish products and prepared foods
Characteristics
- Identification confidence
- unverified | provisional | supported | conflicting Prevents a label, pungent taste or root appearance from being treated as conclusive species identification.
- Cultivar or horticultural group
- recorded name and naming source, or unknown Expected storage-organ form, harvest timing and usable organs vary substantially among cultivated radishes.
- Intended harvest organ
- storage organ | leaves | immature pods | mature seeds | whole young plant | other | undecided Flowering and pod formation can represent either an unwanted transition or progress toward the intended harvest.
- Storage-organ dimensions
- length and maximum diameter in mm, with observation date and measurement method Supports growth assessment and harvest decisions without assuming one normal size for all radishes.
- Storage-organ form and colour
- observed shape, skin colour and flesh colour; flesh unobserved unless exposed Helps assess cultivar consistency and distinguish normal variation from injury or deterioration.
- Developmental stage
- germinating | seedling | vegetative | stem elongating | flowering | pod developing | seed maturing | senescent Determines which identity evidence is available and which harvest or propagation actions remain appropriate.
- Internal storage-organ condition
- unexamined | firm and intact | pithy | hollow | fibrous | discoloured | decaying; multiple observations allowed External size and appearance do not establish internal quality.
- Plant damage
- affected organ, symptom, extent, progression and suspected cause with confidence Separates observable damage from an unconfirmed pest, pathogen or environmental diagnosis.
- Growing exposure
- links to dated temperature, light, water and root-zone observations Provides context for poor swelling, cracking, stress and reproductive transition.
- Reproductive neighbours
- nearby potentially compatible flowering plants, identity confidence, distance and flowering overlap Supports assessment of seed parentage and whether saved seed is likely to preserve the intended cultivar.

Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 10 layers · 10 findings · 20 questions.
Radish identity Establishes whether the observed plant belongs to this registry entry and which cultivated form is being assessed.
A root label or familiar radish shape is insufficient, while legitimate cultivated forms can look very different.
Species evidence
Uses provenance and available botanical characters to support or challenge identification.
Identification basis
Records the evidence for Raphanus sativus and the alternatives that remain plausible.
- Which seed records, supplier labels or botanical observations support identification as Raphanus sativus? provenance
- Which alternative taxa remain plausible, and would mature flowers or pods resolve the distinction? boundary
Cultivated form
Connects the plant to an evidenced cultivar identity and intended harvest type.
Cultivar and purpose
Separates documented cultivar identity from a horticultural type inferred from appearance.
- Is the cultivar or horticultural group documented, inferred from morphology or unknown? provenance
- Is this plant being grown for its swollen storage organ, leaves, immature pods, seeds or another stated purpose? definition
Storage organ and foliage Records vegetative growth and organ quality relative to the cultivated form.
Useful radish assessment must distinguish expected shape and growth from poor swelling, damage and hidden internal defects.
Storage-organ development
Assesses the swollen root-hypocotyl region without assuming every cultivar produces the same harvestable form.
Swelling and form
Tracks storage-organ size, shape and consistency with the intended crop.
- What are the storage organ's length, maximum diameter, shape and exposed skin colour at this observation? measurement
- Does this cultivated form normally require substantial storage-organ swelling for its intended harvest? boundary
Vegetative quality
Assesses foliage and internal storage-organ condition as distinct observations.
Leaf and internal condition
Preserves the difference between visible plant vigour and quality established through internal inspection.
- What leaf growth, colour, wilting or tissue loss is present, and how has it changed? measurement
- Has a harvested organ been cut to check for pithiness, hollowness, fibrous texture or internal discolouration, and which plant does that observation represent? provenance
Development and growing response Interprets developmental transitions and growth problems using dated growing conditions.
Calendar age alone cannot establish radish maturity, and the significance of flowering depends on the intended harvest.
Developmental transition
Tracks emergence, vegetative development and the transition to flowering.
Stage and bolting
Records reproductive transition separately from whether that transition is desirable.
- What are the sowing or emergence date and the current observable developmental stage? measurement
- Given the intended harvest organ, should stem elongation or flowering trigger harvest assessment, continued growth or retention for seed? action
Growth-response context
Links observed growth to relevant exposures without assigning a cause from symptoms alone.
Restricted or irregular growth
Investigates poor swelling, misshapen organs and cracking through the plant's growth history.
- What evidence is available about crowding, root-zone obstruction, water variation and temperature during storage-organ development? provenance
- Which cultivation change is supported by that evidence, and what subsequent plant response would indicate improvement? action
Damage and harvest readiness Evaluates organ-specific damage and readiness for the intended use.
A radish may reach its target size while containing tunnels, cracks or internal deterioration, and different harvest organs need different criteria.
Damage assessment
Records symptoms and their distribution before inferring causes or selecting interventions.
Organ-specific symptoms
Locates damage in foliage, storage organs or reproductive structures and preserves diagnostic uncertainty.
- Are there leaf holes, root tunnels, abnormal swellings, cracks or soft lesions, and what proportion of the relevant organ is affected? measurement
- What direct observation or diagnostic evidence supports the suspected cause rather than another explanation? provenance
Organ-specific harvest
Determines readiness using the intended organ, cultivar expectations and observed condition.
Harvest decision
Makes the evidence for harvesting, waiting or rejecting an organ explicit.
- Which size, tenderness, internal-quality or pod-development criteria define readiness for this cultivar and intended use? definition
- Should the target organ be harvested now, reassessed later or excluded from the intended use, and which observation supports that decision? action
Flowering, pods and seed Tracks reproductive development, pod use and the provenance of saved seed.
Radish pods can be harvest targets or seed-bearing structures, while seed parentage cannot be inferred solely from the appearance of the parent plant.
Pod destination
Distinguishes immature pod harvest from retention through seed maturation.
Pod use and stage
Records pod development against the selected purpose.
- Are these pods intended for immature harvest, botanical identification or mature seed collection? definition
- What pod texture, colour, seed filling and drying observations establish their current stage? measurement
Seed parentage and performance
Records what is known about seed origin and subsequent germination.
Saved-seed confidence
Keeps maternal identity, pollen-source uncertainty and observed germination separate.
- Which parent plant produced the seed, was its cultivar identity or hybrid status documented, and which potentially compatible plants flowered nearby? provenance
- What germination result has been measured for the collected seed, using what sample size and test conditions? measurement
What the second pass must settle
- Which taxonomic authority should govern the Raphanus sativus boundary and its relationship to names treated elsewhere as synonyms or infraspecific taxa?
- Which regional identification characters reliably distinguish cultivated, escaped and wild Raphanus material when mature fruits are unavailable?
- Which cultivar-specific criteria should define harvest readiness and unacceptable pithiness, fibre development or pod toughness?
- Which temperature, day-length and growth-history responses are supported for the cultivar groups represented in the registry?
- What reproductive compatibility and seed-production evidence is needed to make a justified claim that saved seed will preserve a particular cultivar?
