There's no reason to dismiss Ichy's findings out of hand because of the off chance that there might be another cause for his spike in blood pressure...
Funny, that's pretty much the same reason you give when you dismiss photographs from space.
At least Ichy's experiments are repeatable and verifiable.
You mean the experiments that show plants have a hardening cell develop in the presence of moonlight, which is the same cell that grows naturally and dies in the presence of sunlight to allow the stem of the plant to bend towards the dominate light source for more efficient photosynthesis as well as growing as a reaction to physical stress (such as constant shaking) to keep the plant's stem rigid enough to survive the environment? I fail to see how the development of the cells pose any problem. Even if you want to use it as a reaction to stress, Humans and other animals suffer no ill effects to wind yet the plant will produce these cells in the presence of strong wind.
All he's done is show that a specific species of plant, when exposed to natural moonlight, causes slightly elevated growth of a specific cell type used in stem rigidity. Leaping to "moonlight is harmful" is a leap of faith and not actual science.
It's the same thing as saying dog bites = Harmful moon rays.
Collenchyma grows specifically in response to stress with excess. They were harmed.
No, collenchyma grows naturally AND specifically to physical movement, not harm. It's function is to provide a rigidity to the plant to ensure that it gathers the most sunlight.
I would also like to point out that plants don't get harmed when they're shaken. Why? Well let's look at how a plant works shall we? A series of tubes that move nutrients from the roots, through the stem, and into the leaves. These tubes are extremely flexible and resilient. In no way is a plant harmed when it's shaken. It would be like harming a wet noodle by shaking it.
Now, if the collenchyma became broken, THEN I'd say it was harmed.
Unless you can tell me what kind of harm they actually had. And remember, mechanical stress is not harm. If it was, every wind gust would be harmful to plants.
