Thermal tolerance limit
nounPronunciation: /ˈθɜːml ˈtɒlərəns ˈlɪmɪt/
The maximum or minimum temperature threshold beyond which a plant cannot survive or maintain normal metabolic functions. This limit varies by species and is influenced by acclimatization history and developmental stage.
Plain English
The highest or lowest temperature a plant can tolerate before it dies or stops functioning normally.
Etymology & History
Usage
"The thermal tolerance limit of tropical species was exceeded during the unexpected frost event."
Style guide notes: Specify units (°C or °F) and whether limit refers to maximum or minimum when reporting thermal tolerances.

Frequently Asked Questions
Can thermal tolerance limits change in plants?
Yes, through cold or heat acclimation, plants can shift their thermal tolerance limits over time.
Why do tropical and temperate plants have different thermal limits?
Evolutionary adaptation to their native climate ranges produces species-specific thermal tolerance thresholds.
Why Test Candidates on This?
Thermal tolerance limits are critical assessment criteria in climate change resilience studies.
