Abstract: Abstract. Polyethylene glycol (PEG-4000) solution in concentration from 7.5 to 200 g 1-1 r~pidly induced water stress of the desirable level in primary leaves of bean plants. At the same water saturation deficit, however, the water potential as well as the osmotic potential were considerably lower in leaves of PEG - treated plants than those in leaves of plants naturally wilt. ing due to a gradual decrease in substrate moisture.
