A deeper understanding of the biomechanics of the tree shows that it is adept at self-construction.
Building improvement consists in constantly maintaining equal stresses over the entire surface of all structural elements. Adaptive, compensatory growth or hormonally controlled repair strengthens areas that are weak or overburdened. In these places, there are characteristic deformations, which are a constant symptom. We can actually talk about the lifelong mechanical self-improvement of the tree. In tree stats, particular importance is given to considerations of wood interaction and initial growth stresses. In each of the protective mechanisms, the expansion or contraction of the active elements of the aquatic system causes stresses.
wood reaction
In response to mechanical stress, the tree modifies its wood; Reaction wood is produced, which varies in terms of location, properties, cell structure and organ shape. It is formed in organs subject to pregnancy, and with it a forced and prolonged change of the normal direction of growth and a disturbed optimum situation. The purpose of the wood reaction is to return the member or part of it to its optimal position. They can obviously be observed in places with greater overload, for example in the stern, trunk, forks and bases of branches. Previously, reaction wood was known as straightening fabric.
Conifers form pressed wood, also known as compressive wood, on the slope, usually the leeward side of the logs; Always on the underside of sloping trunks or branches (hypoxia). During the maturation of the coils, their walls absorb water (hygroscopicity) and swelling occurs. In the present arrangement, the swelling coils – by blocking each other – cannot be arbitrarily lengthened and the pressure increases. As a result of changes…
