The correct spelling is “thigmotropism”, and it refers to the directional response of a plant organ to touch or physical contact with a solid object. This directional response is generally caused by the induction of some pattern of differential growth.

This phenomenon is clearly illustrated by the climbing tendrils of some plants, such as the sweet pea. The tendrils actually “feel” the solid object, which results in the coiling response.
