Abstract
Nitrate reductase activity (NRA) in different compartments (leaves, inflorescence stalks, flowers and tuberous roots) of Asphodelus aestivus Brot (Liliaceae) and actual mineral nitrogen (NO(3)(-)-N and NH(4)(+)-N) in soil surrounding the roots were investigated over one year Although the highest NRA was found in the leaves, the other plant compartments, such as flowers and tuberous roots, also have nitrate assimilation capacity High nitrate assimilation capacity under suitable conditions is considered to be a good strategy for development and dominance of this species in Mediterranean environments There was a seasonal variation in nitrate assimilation in leaves and actual NO(3)(-)-N content of soils Depending on actual nitrate content of soils, nitrate assimilation increased in winter.
