Abstract
In a laboratory experiment, a strong linear relationship (R-2 = 0.92) was f ound between the velocity of a defined liquid streaming through a stem of S alix alba L. and the electrochemical potential (streaming potential) measur ed between two inserted electrodes. Field measurements confirmed that diurn al patterns of sap velocity inferred from streaming potentials deliver reas onable estimates comparable to traditional methods.
