Labeling and traceability

See it

Good labeling connects a physical vessel to a batch, plant identity, stage, date, and lineage. If a label is ambiguous, the biological work can become unusable even when the plant itself looks healthy.

Understand it

Use durable identifiers that remain legible in the culture environment.
A batch identifier should connect to a richer digital record.
Lineage helps distinguish parent material from derived subcultures.
Important boundary

Never reuse an identifier in a way that can make two cultures appear to be the same record.

Try it

Explain the concept in your own words, then identify what plant, explant, stage, units, source, or observation context would need to be preserved before applying it.
