What effect does music have on plant growth?

Research:

Many experiments have been done to see what music's effect on growing plants is. Does music help or hinder a plants growth? Many studies have been done and it has become a very interesting subject. This experiment will give us an understanding on whether or not music effects plant growth. In our experiment, we will use rock music and classical music to test the plant growth.

Hypothesis:

We think that the classical music will help the plant growth and that the rock music will hinder its growth since studies have showed that classical music even concentrates the human brain and is good for you.

Material:

1. Three of the same type of plant
2. 2 small stereos or boom boxes with CD players
3. A rock CD
4. A Classical CD

Procedure:

Take the three plants and label them, one with classical, one with rock, and one with no music. Put all them in separate rooms and put the rock music by the rock plant, put the classical CD by the classical plant and leave the other plant in a quite room with no exposure to music. Water them daily and after a week, record your results on how each plant is doing.

Record And Analyze Data:

After one week of experimenting, the following were the results. The one that was in the best condition was the plant that was in the room with classical music. The second best plant was the one in the room with no music and the one that didn't do so good was the one in the room with rock music..

this same experiment was done by another group of scientists.. below is their result,

CAN plants hear? They all respond to light, which affects how they optimise growth and survival. Plants also have a sense of touch, allowing them to stiffen in response to wind, and a "taste" for nutrients. But whether they respond to sound is a mystery.

Now Mi-Jeong Jeong of the National Institute of Agricultural Biotechnology in Suwon, South Korea, and colleagues claim to have identified two genes in rice that respond to sound waves. They also say that the promoter of one of the sound-sensitive genes could be attached to other genes to make them respond to sound too.

The findings follow a host of similar, but unsubstantiated, claims that plants respond to sound. If the researchers are correct, they say their discovery could enable farmers to switch specific crop genes on and off, such as ones for flowering, by blasting sound into the fields. That might be cheaper and more environmentally friendly than proposed techniques, such as activating genes with chemicals.

Farmers could switch crop genes on and off by blasting sound into fields
The researchers discovered the sound-responsive genes by exposing rice plants to noise while monitoring levels of gene activity. At first they played the plants 14 different classical pieces, including Beethoven's Moonlight Sonata, while monitoring for differences in the expression of various genes. They only found differences, however, when they played the plants sounds at specific frequencies.

The genes rbcS and Ald became more active at 125 and 250 hertz and less active at 50 hertz. As both are known to respond to light, the researchers repeated the tests in the dark and found that the two genes still responded to sound. "These results suggest that sound could be an alternative to light as a gene regulator

this is an excellent advancement in the field of botany
do plants show these variations even the production???????
how the sound waves effect the physiology of the plant?

Hi Gokul,
Its an interesting info.......
Are there any examples of these kind ......i mean plants which grow with the help of MUSIC.
Is this being prasticed any where?
