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 identify Sesamum indicum, assess its development and condition, and justify cultivation, propagation or harvest decisions from recorded evidence.
It can be Inspect and sample leaves, flowers, capsules and seeds to support or revise an identification.; Trace planting material to an accession or parent lot and establish a documented propagation trial.; Monitor development at specified plant positions and across a defined population sample.; Investigate stress or damage and select a locally supported cultivation response.; Compare capsule maturity, opening and seed retention to choose a harvest approach and timing.; Harvest seeds into a linked lot while preserving parentage, maturity and handling evidence..
Distinguishing features
Inspect mature seed surfaces when distinguishing S. indicum from S. radiatum: smooth or slightly veined faces support S. indicum, whereas radial sculpturing supports S. radiatum. [Kew botanical descriptions](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:675971-1/general-information)
Check seed margins for conspicuous wings: S. indicum seeds are unwinged, although an inconspicuous fringe may occur; conspicuously winged specimens require another identification. [Kew botanical descriptions](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:675971-1/general-information)
Compare mature capsules with the documented oblong, four-grooved, short-beaked form; combine this with reproductive evidence rather than identifying from capsule silhouette alone. [Kew botanical descriptions](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:675971-1/general-information)
Check the combination of narrower upper leaves, potentially lobed lower leaves and pale tubular flowers; variable foliage makes a single leaf insufficient. [Kew botanical descriptions](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:675971-1/general-information)
Do not separate species or confirm cultivars by black, brown or white seed colour alone: all occur in S. indicum. [Kew botanical descriptions](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:675971-1/general-information)

- Human nutrition, allergy diagnosis and medicinal efficacy
Characteristics
- Identification confidence
- unresolved; provisional; confirmed against a documented reference Controls whether species-specific decisions are justified.
- Cultivar or accession provenance
- Linked accession, cultivar declaration, supplier and parent seed lot; unknown allowed Connects expected behaviour to evidence about the actual planting material.
- Seed surface and margin
- Surface sculpture, wing or fringe presence, colour and maturity, with magnified images Supports differentiation from related sesame species without treating colour as decisive.
- Developmental stage distribution
- Emergence, vegetative growth, flowering, capsule filling, maturation and senescence; concurrent stages allowed Keeps observations of different organs or sampled plants from being collapsed into one misleading stage.
- Capsule-bearing architecture
- Height in cm; branches per plant; capsule-bearing nodes and capsules per sampled plant Locates reproductive development and supports comparable yield-potential observations.
- Root-zone water condition
- Drying; adequately moist; saturated; standing water; unknown, with observation duration Provides context for establishment failure and water-related stress assessments.
- Damage burden
- Percentage of sampled plants or organs affected, with symptom type and sampling denominator Separates isolated injury from a population-level problem.
- Capsule opening and seed retention
- Percentage of sampled mature capsules open; retained or lost seed mass under a stated method Supports harvest decisions using observed loss risk.
- Seed moisture
- Percent moisture, specifying wet or dry basis, method and sampled capsule positions Makes maturation and harvest assessments comparable without assuming a universal threshold.
- Propagation performance
- Germination and emergence percentages, each with conditions, duration and sample size Distinguishes tested seed performance from successful establishment in the growing environment.

Sesame identity Evidence that the observed plant belongs to the registered species and to any claimed cultivated lineage.
Species identity and cultivar identity require different evidence and support different decisions.
Diagnostic organs
Combined observations of foliage, flowers, capsules and mature seeds.
Species determination
Record the identification, diagnostic observations, reference used and unresolved alternatives.
- What capsule form and mature seed surface or margin evidence supports S. indicum and excludes the locally plausible alternatives? definition
- Which reference, specimen or expert determination supports the identification, and which diagnostic organs were unavailable? provenance
Cultivated lineage
Accession and cultivar claims attached to the identified sesame plants.
Lineage evidence
Keep supplier labels, accession records and observed traits distinct, including uncertainty about mixtures.
- Which parent seed lot or accession establishes the claimed cultivar identity? provenance
- Do differences among plants indicate expected variation, a possible mixture or an unresolved identification problem? boundary
Establishment and site response The transition from sown sesame seed to an established plant and its observed response to growing conditions.
Sesame is sensitive to waterlogged conditions, making drainage context relevant to establishment and stress assessment. [NParks species account](https://www.nparks.gov.sg/florafaunaweb/flora/7/2/7200)
Seed to seedling
Evidence linking seed performance, sowing conditions and actual emergence.
Establishment outcome
Record germination separately from emergence and subsequent seedling survival.
- What proportions of tested seeds germinated and sown seeds emerged, under which conditions and observation periods? measurement
- What evidence supports retaining the stand, resowing or investigating seed quality and seedbed conditions? action
Root-zone response
Plant observations interpreted alongside moisture, drainage and temperature records.
Water stress assessment
Record exposure and plant response without equating wilting or yellowing with a confirmed cause.
- What root-zone moisture or standing-water observations coincide with wilting, yellowing or growth arrest? measurement
- Which additional observation would justify irrigation, drainage correction or continued monitoring for these plants? action
Flowering and seed development Spatial and temporal observations of sesame flowers, developing capsules and seed formation.
Harvest and propagation decisions need the distribution of reproductive states across the plant and sampled population.
Reproductive progression
Flower and capsule development located by date, branch and node.
Stage distribution
Represent flowering, filling and maturing structures separately wherever they coexist.
- Which sampled nodes or branches bear flowers, filling capsules and mature capsules on the observation date? measurement
- What observable criteria distinguish a filling capsule from a mature capsule for this accession? definition
Seed parentage
The reproductive history needed to interpret seed intended for propagation.
Pollination provenance
Record open pollination, controlled selfing or crossing and the evidence supporting any parentage claim.
- Were seed-bearing flowers openly pollinated, isolated or deliberately crossed, and what records support that history? provenance
- Is the evidence sufficient for the intended parentage claim, or must pollen parentage remain unknown? boundary
Sesame health and integrity Damage to sesame plants and the evidence needed to judge its cause and reproductive consequences.
Leaf injury, root or stem dysfunction, and capsule damage affect different capabilities and require separate observations.
Symptom localization
Symptoms located on roots, stems, leaves, flowers or capsules and mapped across sampled plants.
Damage pattern
Record incidence, severity and progression while preserving the distinction between symptoms and diagnoses.
- Which organs are affected, how many sampled plants show symptoms, and how has the pattern changed? measurement
- What inspection or diagnostic result supports a pest, pathogen, nutritional or physical explanation? provenance
Reproductive capacity
Consequences of damage for plant survival, capsule integrity and recoverable seed.
Damage response
Connect the affected sesame organs to a justified next action and a subsequent response check.
- How much lodging, stem breakage or capsule injury is present, and what reproductive structures remain intact? measurement
- What locally supported evidence justifies treatment, removal, separate harvest or monitoring, and how will its outcome be checked? action
Capsule retention and harvest The relationship between seed maturation, capsule opening and recoverable seed.
Measured shattering resistance varies among sesame genotypes, so harvest decisions need accession-specific observations. [Experimental assessment of sesame shattering](https://doi.org/10.1186/s44399-025-00008-8)
Maturity and opening
Separate seed maturity from capsule opening and actual seed loss.
Retention assessment
Record capsule opening and retained seed under a stated sampling and handling method.
- What fraction of sampled mature capsules has opened, and what seed loss is observed before and during handling? measurement
- What evidence supports the claimed shattering behaviour of this accession under the present conditions? provenance
Harvest decision and handoff
A justified harvest decision and traceable transfer from parent plants to detached seed.
Harvest readiness
Combine maturity distribution, measured moisture, observed retention and the intended harvest method without imposing an unverified universal threshold.
- Does the observed maturity and retention profile justify harvesting now with the proposed method, and which local criterion supports that decision? action
- Which parent plants or sampled population produced the harvested lot, and which quality or storage decisions pass to its separate model? boundary
What the second pass must settle
- Which regional identification key and voucher material adequately distinguish S. indicum from all locally plausible Sesamum species, especially when mature seeds are unavailable?
- Which accession-specific observations reliably distinguish physiological seed maturity from readiness for the intended harvest method?
- Which moisture and capsule-retention thresholds have been validated for the local cultivar, climate and equipment?
- Which locally important diseases and pests require dedicated observations, diagnostic methods or intervention thresholds?
- What isolation and parentage evidence is sufficient for the intended seed-saving or breeding use under local pollination conditions?
