The effects of music on plants
-------------------------------------------------
What, if any are the effects of music on plant's?

seem's like a strange subject, i know but interesting non the less,a good few studies have shown positive effects on plants that music was played too,i remember a few yrs back that i saw an article in anewspaper about Prince Charles playing classical music in his "royal" greenhouse.

But does it really effect plant growth?

or is it just another old wife's tale/urban legend? have a read of this then you decide.....

In 1973, a woman named Dorothy Retallack published a small book called The Sound of Music and Plants. Her book detailed experimentsthat she had been conducting at the Colorado Woman’s College in Denver using the school’s three Biotronic Control Chambers. Mrs. Retallack placed plants in each chamber and speakers through which she played sounds and particular styles of music. She watched the plants and recorded their progress daily. She was astounded at what she discovered.
Her first experiment was to simply play a constanttone. In the first of the three chambers, she played a steady tone continuously for eight hours. In the second, she played the tone for three hours intermittently, and in the third chamber, she played no tone at all. The plants in the first chamber, with the constant tone, died within fourteen days. The plants in the second chamber grew abundantly and were extremely healthy, even more so than theplants in the third chamber. This was a very interesting outcome, very similar to the results that were obtained from experiments performed by the Muzak Corporation in the early 1940s to determine the effect of "background music" on factory workers. When music was played continuously, the workers were more fatigued and less productive, when played for several hours only, several times a day, theworkers were more productive, and more alert and attentive than when no music was played.

Dorothy Retallack and Professor Broman working with the plants used in music experiments. For her next experiment, Mrs. Retallack used two chambers (and fresh plants). She placed radios in each chamber. Inone chamber, the radio was tuned to a local rock station, and in the other the radio played a station that featured soothing "middle-of-the-road" music. Only three hours of music was played in each chamber. On the fifth day, she began noticing drastic changes. In the chamber with the soothing music, the plants were growing healthily and their stems were starting to bend towards the radio! In therock chamber, half the plants had small leaves and had grown gangly, while the others were stunted. After two weeks, the plants in the soothing-music chamber were uniform in size, lush and green, and were leaning between 15 and 20 degrees toward the radio. The plants in the rock chamber had grown extremely tall and were drooping, the blooms had faded and the stems were bending away from the radio. Onthe sixteenth day, all but a few plants in the rock chamber were in the last stages of dying. In the other chamber, the plants were alive, beautiful, and growing abundantly.

"Chaos, pure chaos": plants subjected to Led Zeppelin and Jimi Hendrix didn't survive Mrs. Retallack’s next experimentwas to create a tape of rock music by Jimi Hendrix, Vanilla Fudge, and Led Zeppelin. Again, the plants turned away from the music. Thinking maybe it was the percussion in the rock music that was causing the plants to lean away from the speakers, she performed an experiment playing a song that was performed on steel drums. The plants in this experiment leaned just slightly away from the speaker;...
