Evaluation of Anatomical and Physical Properties of Juvenile/Mature Wood of Populus alba and Populus × euramericana

In this study Populus alba native clone and Populus euramericana 476 clone trees from Gorgan University educative forest were used. Some applied anatomical and physical properties of these species were determined. Results showed that the juvenility age for both species is approximately 10 years .In...
