None of them replicated it :[. They were more interested in helping me submit my findings correctly to an article than reviewing them to be honest.
So none of them agreed that your conclusion was valid?
I found a
old article which says in its Abstract - A second group of Datura stramonium plants was placed in total darkness to determine the effect of such treatment on the quantity of wall thickening in the collenchyma tissue. Measurements indicated that when plants were placed in the dark for extended periods a great reduction of wall thickening resulted. It is suggested that reduction of wall material was due to its utilization as substrate for respiratory processes which occur in the plant under such extreme conditions.
So, if plant would have been in total darkness then the Collenchyma would have been decreased. But it didn't. Then I found
Introductory Botany which in page 95 says that Collenchyma provides support. And that Support is crucial function on plants, in part because it allows plants to grow upward, thus enabling them to compete with other plants for available sunlight in a plant-crowded area.
As Ichi didn't put his plants in total darkness but exposed them to the moonlight then I can deduce that the excess collenchyma in Ichi's experiment was only the result of the plant seeking the light and trying to grow in the direction of feeble moonlight that was the only light provided to them.
