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.
