Cannabis/hemp ecotype variation in germination rate and seedling response as salinity and external water potential decline; supports genotype- and treatment-dependent interpretation.
Visual lesson 08
Water potential, salinity & osmotic stress
Trace how reduced external water potential and dissolved salts can slow or suppress water uptake and emergence, while recognizing genotype, seed lot, salt composition, and experimental conditions as important sources of variation.
