Conteúdo: | Citrus trees behaved like other plant speciess in the continuous dynamic exchange of nitrogen molecules in various nitrogenous compounds. A relatively large amount of the nitrogen in citrus leaves was water soluble and the soluble portion remained relatively constant for leaves opd different ages. Protein in excised citrus leaves wass hydrolyzed rapidly, as in true for other plant species. There wass tendeney for nitrogen in old leaves to be translocated to new growth, especially under conditions of nitrogen deficiency, but there were some exceptions. Amides and ammonnia nitrogen portions of the soluble nitrogen were higher and the free amino acids were lower in leaves about to abscise than in leves not ready to abscise.
