Plants Have an “Ear” for Music. Matthew Sedacca, Nautilus, writes about Dan Carlson, Sr., who, after his experience in the Korean demilitarized zone in the 1960s, dedicated himself to “increase plant growth and help reduce, or even eliminate, world hunger.” Carlson studied at the University of Minnesota, trying to learn everything he could about how plants grow. What he discovered was interesting:
Years later, Carlson believed he found part of his answer. He maintained that “green music”—sounds akin to, or recorded from, those found in nature, like birds singing or crickets stridulating—possesses frequencies that boost plant growth and yield rates. He claimed that when exposed to synthesized birdsong, a plant’s stomata—the mouth-like pores on the underside of leaves that absorb water and nutrients and expel oxygen—widen. Before he died in 2012, he listed growing a Purple Passion (Gynura aurantiaca)—a houseplant that usually grows up to a foot—1,300 feet high to the sound of green music as one of his lifetime achievements. It earned him a Guinness World Record.
Yes, it sounds kind of nutty, and some people in the past relied on pseudoscience, but today “plant bioacoustics is a growing field of interest in science.” In fact, in “a recent study published in Scientific Reports, a team of researchers from Yeungnam University in Gyeongsan, South Korea, found, just as Carlson did over 30 years ago, that “green music” can cause plants to undergo biological transformations.”
