This is a question & answer written by the 4th class in Agriculture, of the IIS Ponti of Somma Lombardo for Evidence Network Academy.
In order to grow strong and luxuriant, in fact, trees need the “stress” caused by the movement of the air, in the absence of which several research have shown that they remain lower and more fragile. Also some researchers of the Biosphere 2 In Arizona (USA), a complex of huge greenhouses inaugurated in 1991 with the aim of creating a miniature version of the biodiversity on our planet.
In one of the recreated biomes, the “desert of the fog”, which was to house cactus and shrub plants, the largest trees were particularly weak, despite growing at a good rhythm.
Stress wood. The researchers did not find scarcity of light received or overabundance of carbon dioxide present in the environment. Despite this, they verified that the so -called “stress wood” had not formed in plants which is formed precisely thanks to the mechanical action of the winds, which increases the production of cellulose and lignin and strengthens the trunks.
