A longer growing season results in thicker growth rings and, as a result, higher overall wood production...

However, studies suggest that longer growing seasons contribute to weakening the wood, making trees structurally weaker..

At first sight, faster growth could be interpreted as higher biomass production, which would lead to a higher carbon storage capacity and, therefore, a greater contribution of our forests to the fight against climate change..

A study by the Technical University of Munich in Germany analyzed the growth rate of trees and the characteristics of their wood over the last century..

The study confirmed that trees with a longer growing season produce more wood cells and a thicker growth ring..
