Comparative analysis of the assortment structure of poplar clones I-214 and Pannonia

Abstract

Poplars occupy about 31.4 million ha in the world, while in Serbia poplars spread over the area of 48.000 ha. The subject of this research are artificially raised poplar plantations, consisting of poplar clone I-214 (Populus×euramericana (Dode) Guinier cl. I-214) and poplar clone Pannonia (Populus×euramericana (Dode) Guinier cl. Pannonia). Field activities of collecting data required for this research were conducted in two phases. The first phase of data collection included measurement of tree diameter. Also, the numbering, marking and recording of poplar rows, as well as each poplar in the row, was conducted. The second phase of data collection was conducted after the felling of trees that were selected for detailed measurement of the elements required for theoretical cross cutting. In accordance with the general principles of cross cutting, as well as the principles of maximum financial effect, the qualitative partition of trunks into several variants was performed. The classification of wood assortments was performed on the basis of SRPS wood standards. The share of technical wood for veneer (F and L class) in the analyzed poplar trees clone I-214 is 47.54% of the total volume of wood assortments. When it comes to the clone Pannonia, logs for cutting (quality class II), have the greatest share in total volume of wood assortments with 44.08. There is no statistically significant difference between the total volume and the value of the assortments of the two analyzed poplar clones, except when it comes to assortments for chemical exploitation where statistical differences exist.
