Aims For many terrestrial plants,nitrate is the most important form of available soil nitrogen for ***,many plant species,which grow on acidic,ammonium-dominated soils,exhibit a con-stantly low level of nitrate reductase activity(NRA).Little is known about NRA in high-mountain vascular plants in similar *** tested the hypothesis that high-mountain vascular plants in acidic and ammonium-dominated habitats have low levels of *** Twenty-six plant species of the families Asteraceae,Ericaceae,Poaceae,Polygonaceae,Salicaceae,Pinaceae,Ranunculaceae,Woodsiaceae,Cyperaceae,Juncaceae,Rosaceae and Urticaceae representing different growth forms were investigated in seven native and anthropogenic habitats of subalpine and alpine belts of the Karkonosze(Hercynian middle-mountains,Central Europe),with respect to leaf NRA and mineral nitrogen forms in *** was measured by an in vivo assay for the first time directly in the field using portable water *** Findings An NRA study of vascular plants from high mountains is presented for the first time,and most of the studied subalpine and alpine species were subjected to field measurements for the first time *** among species,families,growth forms and habitats for NRA were *** differences reflected mainly the taxonomical position and in part ecological *** analysis confirmed that variance component showed that enzyme activities were mostly explained by plant species and ***,the subalpine and alpine species from their native habitats are characterized by very low and low ability for nitrate *** also compared NRA with Ellenberg’s N val-ues for the studied *** a regression equation,N values of some species were calculated for the first time and corrected for the others.
