"The sound of rain spurs rice seeds to sprout up to 40 percent faster than they would otherwise, according to a study published today in Scientific Reports."
"What this study is saying is that the seeds can sense sound in ways that can help them survive, said study co-author Nicholas Makris, a professor of mechanical engineering at the Massachusetts Institute of Technology."
"In plants, cellular structures called statoliths are responsible for external sensing. These structures are envelopes of starch that shift and settle at the bottom of plant cells."
New research indicates that the sound of rain accelerates the germination of rice seeds by up to 40%. This study provides the first direct evidence that plants can sense environmental sounds and respond accordingly. The ability of plants to detect sound is linked to cellular structures called statoliths, which help them sense their position and stability. The findings suggest that other plant species may exhibit similar responses to sound, enhancing their survival mechanisms.
