Leaf rolling phenotype
The physical curling or rolling of leaf margins inward as a mechanical response to water deficit, reducing exposed leaf surface area and transpiration rate. This visible morphological adaptation appears as an early stress symptom in many grass and crop species.
Osmotic potential adjustment
