Stress-induced quiescence
noun phrasePronunciation: /ˈstrɛs ɪnˈdʒuːst ˈkwaɪɪsəns/
A reversible reduction or suspension of growth, development, and metabolic activity in response to abiotic stress conditions, allowing resources to be redirected toward stress tolerance. Quiescent organs can resume normal function when stress conditions ameliorate without permanent developmental changes.
Plain English
A temporary pause in plant growth and development that allows the plant to survive harsh environmental conditions.
Etymology & History
Usage
"Stress-induced quiescence in underground buds enables trees to survive prolonged drought by conserving limited water resources."
Style guide notes: Use 'stress-induced quiescence' to emphasize the environmental trigger distinguishing it from developmental dormancy.

Frequently Asked Questions
Is stress-induced quiescence the same as dormancy?
No; quiescence is reversible and triggered directly by stress, while dormancy is genetically programmed seasonal inactivity.
How do plants resume growth after quiescence ends?
Once stress conditions improve and stress signaling decreases, growth hormones like auxin reactivate meristematic cell division.
Why Test Candidates on This?
Important for understanding plant survival strategies and resource allocation prioritization in advanced plant ecology and physiology courses.
