Anthesis
nounPronunciation: /ænˈθiːsɪs/
The period when flowers open and reproductive organs become functional, typically coinciding with pollen maturation and stigma receptivity. This critical developmental stage is highly sensitive to abiotic stress and determines reproductive success.
Plain English
The flowering stage when flowers open and become capable of reproduction, a period vulnerable to environmental stress.
Etymology & History
Usage
"Heat stress during anthesis reduced pollen viability and grain set in rice cultivars, significantly lowering yields."
Style guide notes: Use lowercase unless beginning a sentence; common in agronomic and breeding literature.

Frequently Asked Questions
Why is anthesis critical for crop stress research?
Stress during anthesis directly impairs pollen viability, fertilization, and seed set, determining final crop productivity.
Which stresses most damage plants at anthesis?
Heat, drought, and cold stress during anthesis are most damaging because reproductive tissues are metabolically active.
Why Test Candidates on This?
Essential for crop performance studies and climate change impact assessments on agriculture.
