The paper brings an analysis of root system development (both skeletal and fine roots) of 19-year old Norway spruce (Picea abies /L./ Karst.) of two provenances (from altitudes 320 m a.s.l. and 1100 m a.s.l.) growing on two provenance plots (540 m a.s.l., lowland, modal cambisol; 820 m a.s.l., slope, ranker podzol) by comparing 36 parameters and traits. Research results show that root system emergence is not affected by provenance but rather unambiguously by site, namely by soil type and terrain slope. The two provenances produced identical to uniform root systems: At the altitude of 540 m a.s.l. an anchoring root system of circular floor projection with a rooting depth of 80 cm; at the altitude of 820 m a.s.l. an elliptical superficial root system with a rooting depth of 45 cm. Provenances on the respective plots did not exhibit any differences either in the fine roots biomass, vitality, and specific length or in the type of functional mycorrhiza.
