Negative Gravitropism | Demonstration
Ойын-сауық
Negative gravitropism demonstration showing how mustard shoots react to change in pot position.
Gravitropism is growth or movement response to gravity, observed in plants and fungus. Its is also called - geotropism. Just like phototropism, gravitropism can be positive or negative. To put it simply - positive gravitropism makes plants point same direction as gravity is puling - down, while negative gravitropism is directed upwards.
Plants, well, at least mustard, are ridiculously sensitive to light. Before landing on last setup version for this demonstration, I've tried: using direct light from flash, indirect light from flash (both on weakest power setting), indirect light from 3,5 W 2700K light bulb (lowest wattage I could find for wide spectrum light bulb). In all cases plants pointed toward light source. Though, response was a lot weaker, compared to positive phototropism video ( • Positive Phototropism ... ). I ended up using indirect light from 3,1 W red light bulb, since phototropic response to red light is normally masked by gravitropic response (nph.onlinelibrary.wiley.com/d.... For this reason video is desaturated. Light were places in front of plants but pointed away from them and towards the panel to diffuse light. Exposure times were 1 min 15 s with ISO 200 and f/8. Oh, and yeah, all of this was done in a wardrobe, with all gaps covered to avoid external light. It is a big wardrobe.
Plants on the right are control group.
Most likely reason why all motion ceases in the end - plants ran out of energy.

I'm happy, because you did everything to get those six marks in paper 6.
Wow, so much work put into 1min vid! Thanks for the video!
I enjoy the fact that you added a test group as an example
Dude! What if you place the pot vertically like you did here, but connect its base to a very slow rotating horizontal axis, synchronous to the plant's growth rate, then the plants might adopt a helical shape.

Look up the "Volksgarden Rotating hydroponic system".
Thanks for your hard work. You keep us both educated and entertained at the same time 💚
So what you're telling me is that strategically orienting plants at different stages such that at a certain level they have to grow against their previous length vector, increases their net growth? Noice

omg! I love this! I will be sharing this video with my class, it is so perfect for providing a visual for gravitropism
I just have an absolute fascination torwards plants and botany in general. Thanks alot for making these wonderful videos :)
Poor plants. Every time they finally face the light, they are turned around.

The video shows how plants grow away from gravity, there's no light.

Or you could say, everytime they are turned around they rise against it
Wonderful video, top quality.
You deserve more subscribers! This is a west seeing what I learned in biology being applied in the real world
Keep it up! great teaching material!
Wow i love this chanel! Its really relaxing to watch this
Very interesting and amazing video!
Awesome bruh...... New subscriber.... Much love... Keep up the great work
I LOVE vídeos nice work !! Sin!!!!!!
Well done!!!
Wow super explanation for different types of tropisms 👌👌👌in the same way can you make video on positive geotropism and make more and more videos like this 😀😀👏👏👏👌👌😊
Cool! Thanks for video!
Nice job

I want to do this experiment. Can you tell me about kind of that plants? And I want to know whether you controlled the light.
Wow . Thank you
Wow Beautiful
super cool！
Is negative phototropism a thing for light thats too strong for a plant? I recently purchased a baltic blue and the leaves appear to moving away instead of towards a grow light. Thanks for any input
Wonderful
wow amazing..
I don't understand what the fuck is going on but it's stressfully ominous and cool as hell
great videos
Can anyone give me the link of background music please Very desperate
Leaving my comment here before this video gets viral.
this is cool.
Pure model of anti gravitation! Wow.. :-)
Wow 👌
More videos plz❤
nice bass track
Interesting
@GPhase Please do the time lapse of tulip plant (tulip bulb) it will be very interesting and different from other videos.
So cool.. So light and gravity shapes direction of growth 👏🙂
How do you shoot these videos? please reply
with an artificial light source, what about growing inverted?
Can I use this video on my channel?
That's breakdance for plants!
Please do one that shows root decay after something like spinach has been harvested or the top of a plant has been cut.

Added to plans, might happen eventually.
What bulb do you use for " sunlight"?
what if the plant is upside down?
thats so cool i wish i was a plant
What's the position of light?
Do you save It?
Pranking sprouts be like: 0:18 till the end.
Cool
wow 66676 subs... but nice video!
Can you make a combination of gravitropism and phototropism ?

Yes, that is in to do list.
How do they grow without gravitation
woah these look exactly like this weird looking forest they discovered in poland long ago, got me thinking..
it's about gravity or the light?

An example for the remaking of bodies instantaneously is the perfect remaking within a few days of all the trees in the spring, which are far more numerous than all humanity, together with all their leaves, in exactly the same way as those of the previous spring; and the bringing into being, again like those of previous springs, all the blossoms, fruits and leaves of the trees with the speed of lightning; and the sudden awakening of the uncountable numbers of seeds, grains, and roots, which are the source of the spring, and their unfolding and being raised to life; and reflecting the meaning of "resurrection after death," the sudden raising to life at a command of the upright skeleton-like corpses of the trees; and the reanimation of the innumerable members of all species of small animals; and the revivification of all the sorts of flying insects, particularly those which, continually cleaning their faces, eyes, and wings, remind us of our ablutions and cleanliness, and caress our faces -the resurrection and remaking of all the members of this tribe within a few days every spring before our very eyes together with all the other species, despite being greater in number than all mankind since the time of Adam, provides not one example of the remaking of all human bodies at the resurrection, but thousands.
