- Seeds can sense rain vibrations, accelerating germination as an adaptation for survival.
- Experiments with rice seeds show simulated rainstorms increased germination rates by up to 37%, linked to statolith displacement.
- Acoustic vibrations from raindrops are amplified in water, creating pressures comparable to a jet engine for nearby seeds.
- The study suggests this response may be common in plants, with rice chosen for its underwater growth and gravitropism similarities.
