Abstract
The effect of pruning on tree development and the potential structure of wood assortments was investigated in the poplar Populus × canadensis clone “I-214”. The study was carried out in a permanent sample plot within a poplar plantation established in 2006, in the area of the “Vojvodinašume” Public Company, within the “Gornje Potamišje” Forest Management Unit (Republic of Serbia). Pruning was performed on a total of 325 trees at different stem heights and a total of 13,186 branches were pruned. The average number of pruned branches per tree at the stem height of 5 m was 36, while it was 40 at the stem height of 6 m and 46 at the stem height of 7 m. The average diameter of pruned branches was 1.7 cm. The results showed that there are no significant differences in diameters at breast height between pruned and unpruned trees after two different intensities of pruning. Our results showed that pruning do not impact the long-term growth performance in poplar clone “I-214”, while remarkably improving the quality and economic value of wood assortments obtained from pruned trees.
