Witryna7 kwi 2024 · Thigmotropism is when plants grow in response to touch or contact with objects. For example, vines have small tendrils that curl around walls or trellises. Plants like this don’t usually have strong stems. So, thigmotropism helps them stay upright and keep growing. Plants in the legume, or bean family, often display thigmotropism. Witrynatropism, response or orientation of a plant or certain lower animals to a stimulus that acts with greater intensity from one direction than another.

Darwin himself performed experiments which compared these two responses. He found that in a veritcal bean root, a contact stimulus could divert the root away from the vertical, i.e. thigmotropism overrides gravitropism.
