Plant cultivation that should be characterized by proper yield abilities is often limited in different arable lands for the reason of abiotic and biotic stress factors. Drought stress in plants causes the high content of soluble substances that have a high osmotic potential. The plant adaptation to the high osmotic pressure in drought condition may occur either by natural adaptation to changed environment or genotype population ability under selective breeding. To implement a quick test on drought tolerance, the influence of high osmotic pressure caused by the polyethilengly-col (P.E.G.) solution of different concentrations with molecular weight 8000Da on germinating seeds of Brassica rapa L. was studied.
