      MORAVIA (Czech Republic)
    • Abstract:
      The aim of the study was the evaluation of three experimental plots Novosedly, Krnov, Líšná established in Moravia regions (Czech Republic). Progenies of hybrid aspen from controlled pollination (33 progenies of Populus tremula × P. tremuloides and 4 progenies of P. tremula × P. tremula) were measured at the age of 10, resp. 11 years. Basic quantitative characteristics (height, DBH, stem volume, standing volume) were evaluated and progenies were compared. Best results showed the group of progenies P. tremula × P. tremuloides obtained from crossing of maternal genotypes P. tremula selected in previous progeny tests. Standing volume of this group of progenies ranged among 197–295 m³ . ha–1 in Novosedly experiment, among 163–225 m³ . ha–1 in Krnov experiment. Standing volume of the group of progenies P. tremula × P. tremuloides with maternal genotypes selected only as plus trees in forest stands ranged among 193–208 m³ . ha–1 in Novosedly experiment, among 163–202 m³ . ha–1 in Krnov experiment. Reference progenies of P. tremula × P. tremula (crossing of parent plus trees from forest stands) planted in Krnov exhibited the lowest standing volume (92–105 m³ . ha–1. [ABSTRACT FROM AUTHOR]
