EFFECTS OF IRON ON CERTAIN NITROGENOUS FRACTIONS OF ANANAS COMOSUS (L.) MERR

Abstract

The data obtained in this study of the effects of plus - as against minus - iron cultures in association with those of ammonium- or nitrate-nitrogen on the nitrogenous fractions of the tissues of Ananas comosus are presented and discussed in great detail. The results indicate "that the primary products of ammonium assimilation were amide and amino nitrogen compounds and suggest that protein synthesis in plants supplied with ammonium nitrogen was via these compounds. In the plants supplied with nitrate, protein synthesis from inorganic nitrogen compounds was apparently different than with ammonium".
