| Hence an agent which acts on the organ from outside, induces phototropic change earlier than variation in geotropism. |
| It was shown that gaseous ethylene inhibits both growth and geotropism in plants, and ethylene is endogenously produced by fruits. |
| This is the best way to maximize grow space, minimize power consumption, and utilize geotropism to spread growth auxins throughout the plant. |
| Transversal geotropism is a direction of growth that is vertical to the shoot axis. |
| Sight, phototropism, geotropism, anemotropism, and hydrotropism play a significant role in insect orientation for both oviposition and feeding. |
| No phenomenon of tropic movement appears so inexplicable as that of geotropism. |
