Sounds like there is much to decipher still. Imagine when we determine these frequencies and may be able to apply some type of control or
influence(the good kind of course)
For now, the focus is on learning which plants use which frequencies and what those frequencies are saying … are they anti-predatory? Are they
warning signals to other plants? Gagliano hopes to build the knowledge base of plant frequencies to the point where we could use sound to keep plants
healthy instead of insecticide or pesticide.
Plants seem to exhibit communication and memory, as demonstrated in the doc. Chemicals, vibrations and frequencies are involved. I just think this is
fascinating and will be a big part of our re-evolution soon.
More on plant memory
, as I digress.
Do plants have a memory?
Plants definitely have several different forms of memory, just like people do. They have short term memory, immune memory and even transgenerational
memory! I know this is a hard concept to grasp for some people, but if memory entails forming the memory (encoding information), retaining the memory
(storing information), and recalling the memory (retrieving information), then plants definitely remember. For example a Venus Fly Trap needs to have
two of the hairs on its leaves touched by a bug in order to shut, so it remembers that the first one has been touched. But this only lasts about 20
seconds, and then it forgets. Wheat seedlings remember that they’ve gone through winter before they start to flower and make seeds. And some
stressed plants give rise to progeny that are more resistant to the same stress, a type of transgenerational memory that’s also been recently shown
also in animals. While the short term memory in the venus fly trap is electricity-based, much like neural activity, the longer term memories are
based in epigenetics — changes in gene activity that don’t require alterations in the DNA code, as mutations do, which are still passed down from
parent to offspring.
Maybe memory of a chemical exchange with humans is passed down with specific plants too, genetically opening up a line of communication that is
strengthened by a benefit perhaps.
So what type of sounds do plants make and why?
Scientists at Bristol University used powerful loudspeakers to listen to corn saplings – and heard clicking sounds coming from their roots.
When they suspended their roots in water and played a continuous noise at a similar frequency to the clicks, they found the plants grew towards it.
Plants are known to grow towards light, and research earlier this year from Exeter University found cabbage plants emitted a volatile gas to warn
others of danger such as caterpillars or garden shears.
Wow, imagine being able to activate or increase a plants pest defense systems. I would rather tweak or heighten a plants natural abilities than
redesign or combine them with other species genetically.
But the researchers say this is the first solid evidence they have their own language of noises, inaudible to human ears.
Daniel Robert, a biology professor at Bristol, said: ‘These very noisy little clicks have the potential to constitute a channel of communication
between the roots.

Though often too low or too high for human ears to detect, insects and animals signal each other with vibrations. Even trees and plants fizz with
the sound of tiny air bubbles bursting in their plumbing.
And there is evidence that insects and plants "hear" each other's sounds.
Sounds of changes in air makes me wonder if that could be better felt than heard, by humans.
and the roots emit clicks of a similar tune. Chili seedlings quicken their growth when a nasty sweet fennel plant is nearby, sealed off from the
chilies in a box that only transmits sound, not scent, another study from the group revealed. The fennel releases chemicals that slow other plants'
growth, so the researchers think the chili plants grow faster in anticipation of the chemicals — but only because they hear the plant, not because
they smell it. Both the fennel and chilies were also in a sound-isolated box.
This makes me think chemicals may be just as important as the electromagnetic waves for communication.
Agliano imagines that root-to-root alerts could transform a forest into an organic switchboard. "Considering that entire forests are all
interconnected by networks of fungi, maybe plants are using fungi the way we use the Internet and sending acoustic signals through this Web. From
here, who knows," she said.
Man they should listen to what the fungus has to say and talk about a "forest switchboard."
The technology to hear plant bubbles explode is actually quite simple. Acoustic sensors designed to detect cracks in bridges and buildings catch
the ultrasonic pops. A piezoelectric pickup, the same as an electric guitar pickup, goes through an amplifier to an oscilloscope that measures the
waveform of each pop.
What if one could measurably match the oscillation frequency of a plant? Could any influence be applied? More questions than answers I suppose.
We're working on trying to differentiate these two signals: I'm cold versus I'm really thirsty," Wardell said. "We've already managed to produce a
Seems like lots of sounds are involved, and perhaps even specific ones for various needs.
I just think with common dna and genes, and all this exhibition of varied sounds, humans have the capacity to hear or somehow sense characteristics in
plants. I hope further research may reveal more about this connection and we can put it to good use and begin a more harmonious relationship with
I wonder if like some other species, they have a mating or attracting call of some sort? Do they sing or vibrate as a healthy state of being. I know,
we can't project too many humanistic traits on them, but still curious nonetheless.
Plant intelligence? A good read Here
In my research I discovered a unique group of genes necessary for a plant to determine if it’s in the light or in the dark. When we reported our
findings, it appeared these genes were unique to the plant kingdom, which fit well with my desire to avoid any thing touching on human biology.
But much to my surprise and against all of my plans, I later discovered that this same group of genes is also part of the human DNA.
This led to the obvious question as to what these seemingly “plant-specific” genes do in people. Many years later, we now know that these same
genes are important in animals for the timing of cell division, the axonal growth of neurons, and the proper functioning of the immune system.
But plants don't have neurons, so how can they be defined as able to think?
But while plants don’t have neurons, plants both produce and are affected by neuroactive chemicals! For example, the glutamate receptor is a
neuroreceptor in the human brain necessary for memory formation and learning. While plants don’t have neurons, they do have glutamate receptors and
what’s fascinating is that the same drugs that inhibit the human glutamate receptor also affect plants. From studying these proteins in plants,
scientists have learned how glutamate receptors mediate communication from cell to cell. So maybe the question should be posed to a neurobiologist if
there could be a botany of humans, minus the flowers!
Darwin, one of the great plant researchers, proposed what has become known as the “root-brain” hypothesis. Darwin proposed that the tip of the
root, the part that we call the meristem, acts like the brain does in lower animals, receiving sensory input and directing movement.
Well this subject just kind of blew my mind and I wanted to bring it onboard. I don't think I will see plants the same way anymore.
Hope you enjoyed the information here, and I realize it is a bit scattered, but I did not know there was so much going on and following the related
links just expanded the quest for insight.
