Windy days are when trees weight train. Researchers at Biosphere 2 in Arizona found that trees grown inside the dome would not fully mature and eventually collapse under their own weight. The reason for this failure, researchers discovered, was due to the fact there is no wind inside the dome. An article in the webmag Awesci by Anupum Pant explains:
In the biosphere 2, they had trees growing faster than they would grow in the wild. Also, they found that these trees wouldn’t completely mature. Before they could, they used to collapse. Later it was found that this was caused by the lack of wind in the biosphere. And it turns out, wind plays a major role in a trees life. The presence of wind makes a tree stronger, it is thus able to mature and not fall down due to its own weight.
When plants and trees grow in the wild, the wind constantly keeps them moving. This causes a stress in the wooden load bearing structure of the tree. So, to compensate, the tree manages to grow something called the reaction wood (or stress wood). This stress wood usually has a different structure (in terms of cellulose or lignin content and more) and is able to position the tree where it’d get the best light, or other optimum resources. This is the reason why trees are able to contort towards best light and still survive loads in even awkward shapes. A contorted building like that would easily fall. The tree is able to grow in a more solid manner – thanks to the reaction wood.
