How does disco music affect plants?
I wouldn’t think that music would have a major affect, if any on plant growth. However, a Californian science fair project concluded that silence was best for plants compared with the spoken word and classical music. Whether you can take this example as categoric proof is up to you. I think the most major affect music could have on a plant would be if there was very heavy bass, causing a serious vibration. We know that auxins (plant hormones) allow plants to respond quickly to external stimulation from light and other sources, and it is probable that a plant could have a slight response to say being placed next to a big speaker.
