alleryTreatment of a rosette plant with gibberellin causes sudden shoot elongation followed by flowering. This response is called:
ADormancy
BAbscission
CSenescence
DBolting
Answer & Solution
Correct answer: D. Bolting
1. Rosette plants have very short internodes and a clustered growth form.
2. Gibberellin treatment makes the internodes elongate suddenly, raising the shoot.
3. This sudden shoot elongation followed by flowering is called bolting.
4. Abscission is organ shedding and dormancy is rest, so they are ruled out.
