Descriptor gravitropismo
Entry term(s) geotropismo
Scope note: Crecimiento dirigido de un organismo en respuesta a la gravedad. En las plantas, la raíz tiene gravitropismo positivo (crecimiento hacia abajo) y el tallo principal tiene gravitropismo negativo (crecimiento hacia arriba), independientemente de la posición en que estén colocadas. El gravitropismo de las plantas parece estar controlado por la auxina (AUXINAS), una sustancia reguladora del crecimiento de las plantas. (Concise Dictionary of Biology, 1990).

Scope note: The directional growth of organisms in response to gravity. In plants, the main root is positively gravitropic (growing downwards) and a main stem is negatively gravitropic (growing upwards), irrespective of the positions in which they are placed. Plant gravitropism is thought to be controlled by auxin (AUXINS), a plant growth substance. (From Concise Dictionary of Biology, 1990)
