Investigation of the antomical, biometry and chemical characteristics of juvenile and mature poplar (Populus alba) wood
Samples were prepared from the native poplar species (Populus alba) grown in Mehnan, a region in Bojnourd at the ages 5 and 25 and the anatomical, biometrical and chemical characteristics of the samples sections in three directions (cross section, radial and tangential) of the tree were measured.
