EFFECTS OF THE NITROGEN SOURCE AND CONCENTRATION ON N FRACTIONS IN OLIVE SEEDLINGS

J.L. García, R. Sarmiento, A. Troncoso, C. Mazuelos
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.
