Mostrar más [+] Menos [-]The effect of the source (KNO3, (NH4)2SO4 and NH4NO3) and concentration (5, 10, 20 and 30 mM N) of inorganic nitrogen on total N incorporation and distribution into different fractions (ammoniacal, amino, amide and protein) has been determined in olive seedlings. Increasing concentrations of the nitrogen source resulted in higher total N content in tissues, except for KNO3 at 10 mM N. In addition, ammonium applications clearly increased the N-amino and N-ammoniacal fractions. Incorporation of N into N-amide was not affected significantly by any treatment, and only KNO3 and NH4NO3 additions showed significant increasing concentrations of N-protein fractions.
