I saw this in another forum and thought of sharing it and getting ur thoughts about it......u may think it's a hoax but it was on a tv show (mythbusters episode 23)

so what do u guys think the reason for it to grow better?

Hey guys, have you heard that if you talk to plants they grow better ? Well an experiment was carried out. 2 greenhouses played a recorded play back of sweet talk. another 2 trash talking and cursing. 1 classical music, and the other death metal. 1 was left in silence as the control experiment.
When the results were taken all the plants except the control (the one in pure silence) had grown better. But the one that grew the biggest and produced the highest yield was the one that played death metal! I mean compared to the others it was BIG.

The plants were pea plants, kept for 1 week.

a local forum


plausible
Seven small greenhouses were set up on the M5 Industries roof. Four were set up with stereos playing endlessly looping recordings (as having the Mythbusters actually talk to the plants could contaminate the samples with their expelled carbon dioxide): Two of negative speech, two of positive speech (Kari and Scottie each made one positive and one negative soundtrack), a fifth with classical music and a sixth with intense death metal music. A seventh greenhouse, used as a control sample, had no stereo. The greenhouses with the recordings of speech grew better than the control, regardless of whether such talk was kind or angry. The plants in the greenhouse with the recording of classical music grew better, while the plants in the greenhouse with the recording of intense death metal grew best of all.

feel free to post ur thoughts:) I'll put a comment from the original source later :)

Have heard of this some time back....

But don't know whether this is true of false.

In my point of view:

Plants need light. We all know that. And why do leaves emit green color?
Coz they absorb the other colors.

How do the plants identify different colors? By the frequency of that color.

And the sound does have a frequency too.

So maybe there are different frequencies of sounds which plants can absorb so that it could grow faster.

This is the only intelligent and scientific idea I can think of :D

so u mean plants r sensitive to different colours cos of the frequency is it?
Identifying colours kiwwe?
I thought absorbing colors is something to do with chlorophylls

Ya machang.. It is clorophil. And yes plants are sensitive to different colors... hence different frequencies (wave lengths)

Light can be understood as a combination of energy waves traveling outward from a light source, or as small packets moving from that source at the speed of light (each wave peak would correspond to a single packet). Light always travels at the speed of light, altering only for the material through which it's moving (it goes slower in water, for instance), so a segment of a light beam with wave peaks more separated (a longer wavelength) would have fewer peaks absorbed by a surface (a lower frequency) in any given amount of time, and would hit that surface with less energy. This means short wavelength = high frequency = more energy (http://www.cartage.org.lb/en/themes/Sciences/Physics/Acoustics/General/Wavelength2/freq-wavelength.jpg), long wavelength = low frequency = less energy. The only reason that this is important is that sunlight contains (http://www.nas.nasa.gov/About/Education/SpaceSettlement/75SummerStudy/figure2.3.gif) a fairly wide range (http://telstar.ote.cmu.edu/environ/m3/s2/02sun.shtml) of energy frequencies, but only a few are absorbed (http://generalhorticulture.tamu.edu/lectsupl/Physiol/P24f1.gif) and used by chlorophyll, the energy-capturing molecule of photosynthesis. You can tell a few of the frequencies that are not absorbed by chlorophyll (and a few other light-absorbing molecules) by looking at a plant. That green you see is part of the reflected frequencies of light. For the most part, absorption (http://media.arcus.org/albums/Nikula-Ohlsen_M/normal_Nikula-Ohlsen_TREC_cloroads.jpg) of light is used in an energy conversion that "spits" electrons through a system from the "excited" chlorophyll molecules.

Although land plants absorb a variety of light frequencies, all frequencies are not equally powerful or useful: while plants can absorb both red frequencies and purple frequencies, the purple have shorter wavelengths (http://faculty.colostate-pueblo.edu/linda.wilkes/111/3c.1.jpg) and carry more energy. This is one of the reasons why "plant lights" are distinctly purple.

i've heard that cos of the high frequency the particles in wind moves faster so it helps respiration rate to increase n etc.

cud this be true?

I think its true........

i can remember one lesson in our year 7 or 8 english text book about this :)

In my op,the plants need to be close to human touch,in a sense it is taken well care of.Sound might to do something acoording to the frequency.
