Abstract:
Poplar trees are the fastest growing trees in the northern hemisphere and it woods is suitable for a variety uses and they are the most important resource of wood production. For this reason they are best plant for wood culture. Geographical and climate diversities have important effect in height and diameter growth. This study was established at Esfahan, Fozveh Experiment Station (EFES) in 1370 in order to evaluate the height, diameter and wood production of 14 clones Poplar containing 5 P. euramericana, 4 P. deltoides, 3 P. alba and 2 P. simonii and P. ciliata. The highest value of survival (100 %) tends to P. alba var. nivea P. d. 72/51 and P. e. 45/51 while the least value of survival (0%) tend to P. d. 69/55. The highest height tends to P. e. I 214 (18.1m), P. d. 72/51 (18m) and P. e. triplo (18m) and the least height tend to P. simonii (9.6m) and P. ciliata (11.7m). The highest diameter tend to P. d. 72/51 (25.6cm), P. e. I 214 (25.2 cm) and P. e. vernirubensis (24.9 cm) and least diameter tend to P. simonii (14.6 cm), P. alba var. nivea and P. ciliata with 16cm. The highest total wood production tend to P. d. 72/51 with 265 m3/ha, P.e. I 214 with 255.4 m3/ha and P. e. vrnirubensis with 250.2 m3/ha and least wood production tend to P. simonii (43.3 m3/ha), P. ciliata (70 m3/ha) and P. alba var. nivea with 74.2 m3/ha.
