Firing and Resetting Characteristics of Carnivorous Utricularia reflexa Traps: Physiological or only Physical Regulation of Trap Triggering?

Original language description

Using an electronic position sensor, trap thickness as a measure of water flow was monitored in large Utricularia reflexa traps. Ether, known to inhibit membrane ion channels in animals, gradually and significantly decreased the trap resetting rates, while the mechanical trap stimulation to fire was not influenced. NaN3 (0.5 mM) added to partly reset traps did not influence the magnitude of the next firing but very markedly reduced the resetting rates to ca. 30 % of the controls. Reset traps refrigerated at 2 oC could normally fire but their resetting rates were only around 6-9 % of the controls at room temperature. Wet traps kept in humid air were able to normally fire and reset. Generally, when all these treatments allow the traps to reset the subsequent firing of reset traps is not inhibited. Our data indirectly support the purely physical (mechanical) concept on the regulation of Utricularia trap triggering.
