Heat-induced changes in surface electrical potentials of steam and leaf. (A) VP propagated into leaf (n = 17). (B) Only electrical reactions of small amplitude (<15 mV) propagated into leaf (n = 4). VP induced by heating tip of another leaf (arrow), and ES and EL, changes in electrical potential measured by electrodes on stem and lamina, respectively.
