Rooting
By the end of this lesson
- Distinguish in-vitro and ex-vitro rooting
- Assess root quality beyond count
- Record the rooting route actually used

Rooting prepares suitable shoots or plantlets for root development where the propagation system requires it. Some protocols root in vitro; others use ex-vitro rooting or combine rooting with acclimatization.
Understand it
Distinguish in-vitro and ex-vitro rooting
Rooting strategy is plant- and protocol-dependent.
Rooting strategy is protocol-dependent; some systems root in vitro and others ex vitro.
Assess root quality beyond count
Root number alone is not the only quality indicator.
Rooting quality concerns more than quantity, including whether the plantlet is suitable for subsequent growth.
Record the rooting route actually used
Record whether rooting occurred in vitro or ex vitro.
Record the route that actually occurred rather than forcing all systems into the same stage history.
Worked example
A protocol roots shoots after removal from culture rather than in a separate in-vitro stage. Record that route and later plantlet performance; do not invent a vessel-rooting event for the history.
Explain your decision before opening the worked reasoning below.
Show the worked reasoning
Some systems combine steps or root ex vitro, so a separate vessel-rooting stage is not universal.
A useful comparison preserves both the rooting treatment and the subsequent quality of the plantlet.
Do not assume every micropropagation system requires a separate in-vitro rooting stage.
Try it
How should the example's rooting be documented?
Use the worked example above to explain your answer in your own words before taking the quiz.

Apply it
Use the worked example to write a short decision record: what did you observe, which rule did you apply, and what would you check before acting?
