The factors of quality which affect the sawing yield were researched for poplar plantations, from the aspect of the application of national standards for roundwood. The research was performed on two temporary sample plots, in poplar plantations Populus x euramericana I-214, aged 25 year, in the period 2002-2003. The sample plots were selected depending on the clone species, planting pattern, and plantation flood risk, and branch pruning. The analyzed quality factors are: knots, minimal dimensions, sweep, false heart, ovality and tapering. This study shows, inter alia, that there is not a unique model for all poplar plantations when the value percentage of assortments is determined. although they are homogeneous plantations by structural elements.
