LEVEL 05 · LESSON 01
Initiation
See it
Initiation or establishment is the stage in which selected source material is introduced into culture and an acceptable starting culture is established. The work focuses on identity, contamination management, viability, and early response rather than rapid multiplication.
Understand it
Source plant health and explant identity matter.
The first clean-looking culture is not automatically ready for multiplication.
Record establishment date and observations.
Important boundary
Do not rush a culture forward only because calendar time has passed.
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.
