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.
Hydraulic failure
The disruption of water transport through the xylem system when air bubbles (cavitation) form and block water column con...
Hydraulic failure threshold
The critical water stress level at which plant vascular systems lose hydraulic functionality, resulting in xylem cavitat...
