- One of the most common examples of thigmotropism is seen in tendrils, which wrap around any object with which they come in contact.

- In the absence of this force, the root pattern will depend only on the circumnutating movement, since the negative thigmotropic reaction, dependent on gravitropism, will also be excluded.
- Clematis petioles are positively thigmotropic and its fun to make your own observations of this phenomenon.
- Later experiments proved that the thigmotropic response is possibly the strongest tropic response in plants.
