Nitrate and ammonium assimilation in plant roots and leaves at various levels of nitrogen nutrition



Nitrate and ammonium assimilation in plant roots and leaves at various levels of nitrogen nutrition



Fiziologiya Rastenii 33(4): 722-730



NO3- and NH4+ assimilation in roots and leaves were studied in lupins, maize and Xanthium pensylvanicum fed with various levels of N. At low rates of applied NO3- assimilation occurred mainly in the roots of all spp., but with high rates of NO3- assimilation occurred in both roots and leaves. The rate of N assimilation in plants fed on NH4+ was higher than that of plants fed on NO3-. In lupins NO3- reduction and NH4+ assimilation occurred actively in roots and leaves.
