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.
Ion toxicity
The harmful accumulation of specific ions, particularly sodium and chloride, within plant tissues that exceeds physiolog...
Ion toxicity accumulation
The excessive buildup of specific ions, particularly sodium and chloride, in plant tissues beyond critical threshold con...
ion toxicity threshold
The critical concentration of specific ions (such as sodium or chloride) at which cellular damage occurs and plant growt...
Salinity-induced ion toxicity
