The influence of drought stress modelling by polyethene glycol (PEG) on water status, total soluble protein, proline and carbohydrates content in the roots and leaves tissues of three drought resistance wheat genotypes – Triticum aestivum L. (Podolianka, Favorytka) and Triticum dicoccum Schrank. (Holikovska) have been studied. Tested varieties of bread wheat and emmer wheat presented the resilience-anisohydric strategy for water balance regulation retaining a high level of relative water content, great variability in organic solutes with osmoprotective properties (total soluble protein, total carbohydrates and free proline) accumulation and retaining the level of low molecular weight proteins in response to drought with noticeable distinctions amid the varieties. However, drought stress increased the efficiency of accumulation of osmoprotectants either protein or carbohydrate nature in all three tested varieties of wheat seedlings.
