Detailed researches, made on eleven study surfaces take place on distinct geographical regions. The present work set forth by experimental research, underlines the influence of "stress" abiotical factors, chemical factors (industrial pollution) and climatic factors (frost, dryness, wind). These factors are able to do "grow weak" trees, but the morphological and anatomical strucure alters. The quality of wood has been influenced by anatomical-structural characteristics of wood (depending on the secondary biological action (wood-boring insects, fungi and mistletoe)) which has been instaled in "grow weak trees".
