Abstract :

Tree growth has a great ecological and economic importance and stem analysis is one of the reliable and widely used methods which is used to study the growth of different attributes of the trees. In the present study, we evaluated diameter, basal area, and height and volume growth of two fast growing species (namely Populus deltoides and Taxodium distichum). After falling down the trees, 5 centimeter thick disks at 2 meter intervals were collected and transported to the laboratory. The thickness of the annual rings was measured in two perpendicular directions up to1millimeter precision. The results showed that the highest value of the current growth of diameter of Populus deltoides and Taxodium distichum occurred in 4 and 6 year ages, respectively, equal to 1.5 and 5.4 cm and the highest value of the current basal area growth of Populus deltoides and Taxodium distichum occurred in 9 and 10 year ages, respectively, equal to 0.1 and 0.14 square meters. Furthermore, the highest value of the current growth of height of Populus deltoides and Taxodium distichum occurred in 6 and 9 year ages, respectively, with value of 1.3 m 3.1 m and the highest value of the current growth in the volume of Populus deltoides and Taxodium distichum occurred in 8 and 12 year ages, with a value of 0.094 and 0.1 cubic meters, respectively. Finally, there would be concluded that both of these species in such sites can meet the environmental needs such as green spaces as well as economic goals such as commercial wood product.
