Leaf rolling phenotype

Basic Technical

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.
