| Abstract: | The effect of separate chilling (5 °C for 2 and 4 days) on the shoots and roots of two maize hybrid seedlings on the electric potential, the composition of fatty acids and the ATPase activity in the microsomes of non-chilled leaves and roots (20 °C) was investigated. It has been found that the low temperatures induced on the non-chilled organs gave similar changes to organs exposed to a reduced temperature. The changes consisted of a parallel depolarization of leaf and root membranes and similarly a decrease in the ATPase activity as well as changes in the unsaturation of the membranes' fatty acids. The reduction of the acid content 18:2 was particularly significant, which in the leaf microsomes correlated with a drop in the ATPase activity. The similarity between the reactions of the chilled and non-chilled parts of the plant gives evidence of a 'communication' between the organs which may facilitate a coordinated reaction of the entire organism to stress. The background for these phenomena could be the action potential of the chilled parts of seedlings which, in the non-chilled parts, might produce changes in the structure of biomembranes and in the activity of enzymes.
