MIT Study: Rain Sound Vibes Speed Rice Germination 37%

Summary

Story summary

MIT mechanical engineers Nicholas Makris and Cadine Navarro showed that rain-generated sound vibrations accelerate rice seed germination.
In the six-day experiment, about 8,000 seeds in 3-cm-deep water exposed to simulated rain germinated up to 37 percent faster than silent controls.
A hydrophone confirmed the vibrations matched natural raindrop sounds recorded in Massachusetts wetlands.
The team attributed faster germination to jostling of statoliths, with seeds nearer the surface showing the strongest effect.
