Abstract
Abstract Dehydration of isolated rape hypocotyls ( Brassica napus L. var. oleifera L. cv. Górczański) to a water saturation deficít of about 60% resulted in increased tolerance to subsequent desiccation and to prolonged immersion in water. Dehydration pretreatment followed by restoration of tissue turgidity, caused a decrease in leakage of electrolytes, ultraviolet‐absorbing materials and ninhydrin‐reactive substances from the desiccated or water immersed hypocotyl tissue. A hardening effect of tissue dehydration is supposed to be related to an improved stability of cell membranes.
