Extended Abstract
Introduction and Objective: Due to the high growth rate of the poplar genus, various researchers around the world have shown a special interest in studying various aspects related to this genus over the past few decades. This genus is of great importance not only in the wood and paper industry, but also in the expansion of green spaces in arid and semi-arid areas, especially in areas where the level of the underground water table is high. Pede is a distinctive wood species that is well-suited to arid and semi-arid regions, where it can be used as a sand stabilizer and a means of enhancing afforestation.
Material and Methods: This study was conducted to evaluate the effect of length, diameter, and location of cuttings on the initial growth of P. euphratica seedlings in completely randomized blocks with five replications. The effects of three levels of cuttings length, diameter, and position on the characteristics of height, collar diameter, produced shoot length, number and length of lateral branches, number and dry weight of leaves, dry weight of root and stem, and dry biomass of seedlings were studied.
Results: The results showed that the highest height and dry weight of stem of seedlings were related to the cuttings with lengths of 15 and 25 cm, and the highest dry weight of root was related to the seedlings obtained from cuttings with length of 25 cm. The largest collar diameter and stem dry weight of seedlings were related to the treatment of cuttings with diameters greater than 1.0 cm, and cuttings with diameters of 1.5-2.5 mm had the highest dry weight of leaves. Also, seedlings produced from cuttings taken from the initial section of the branch (10 to 50 cm) had the highest number of leaves.
Conclusion: Generally, the best cuttings were those with a diameter of 1.5-2.5 cm and a height of 25 cm. However, the position of cutting had no significant effect on the biomass of root, stem, dry weight of leaves, number; and length of lateral branches in relation to the length; and diameter of the cuttings. Considering the resistance of Euphrates poplar to drought, salinity; and high environmental temperature, it can be considered as a suitable option for planting in dry and semi-dry regions and even sand dunes.
