Sažetak
Growth characteristics of three black poplar clones, PE 19/66, S6-7, and M-1, were investigated in the field experiment established at plant distance of 5m x 5m in the protected area of central Danube basin, on the fluvisol of sandy-clayey form, after ten years of culture
development. The characteristics of diameter, height and volume growth of medium trees show significant differences among the investigated black poplar clones. The research clearly highlights the significance of the clone (species) of black poplar at establishing the plantation for different purposes: clones PE 19/66 and S6-7, (Populus deltoides Bartr.) under the research conditions of the habitat and planting distance reach the culmination of average volume increment 11 years since the beginning of planting, reaching a wood volume of 220-290 m3·ha-1 for the purposes of combined production of technical and pulp timber. Clone M-1, a hybrid of domestic and American black poplar (Populus x euramericana (Dode) Guinier), demonstrates different growth properties, while the culmination of average volume increment at age 15 since the planting is estimated to have a considerably better assortment structure.
