Abstract: Touch initiates rapid contact coiling in plant tendrils. Besides touch rapid contact coiling could also be initiated by immersing the tendril in liquid containing electrolytes. Liquids with poor electrolyte or non electrolytes did not initiate rapid contact coiling. This observation is strongly suggestive of involvement of electrical charge in the initiation of rapid contact coiling in plant tendrils. Disturbance of electrical charge by touch (like modern touch screen) is likely used to send a signal to the interior of the cell affecting its turgidity. It is proposed that tendril of bottle gourd uses neutralization of electric charge for signaling.
