Abstract :Nitrate reductase activity insert ignore into journalissuearticles values(NRA); was investigated in diferent parts of some Verbascum L. species insert ignore into journalissuearticles values( Scrophulariaceae); collected from different altıtudes of Uludag Mountain, Bursa Turkey. NR activities were compared with respect to insert ignore into journalissuearticles values(1); different plant organs, insert ignore into journalissuearticles values(2); different Verbascumspecies and insert ignore into journalissuearticles values(3); samples collected from different altıtudes insert ignore into journalissuearticles values(120-1850 m);. The highest levels of NRA were found for all species in the leaves. Significant differences were determined between the samples collected from different altıtudes. Despite the NRA is the highest in V. olympicum Boiss., it is the lowest in V. lagurus Fisch. & Mey. Furthermore the correlation between NRA values in aboveground organs of species and altıtude is significant.
