Quantification of Cyanamide in Young Seedlings of<i>Vicia</i>Species,<i>Lens culinaris</i>, and<i>Robinia pseudo-acacia</i>by Gas Chromatography-Mass Spectrometry

Abstract

We quantified the cyanamide content of young leaves of nine Vicia species, Lens culinaris, and Robinia pseudo-acacia using a modified analytical procedure that made it possible to measure the cyanamide content of a single leaf. Recent molecular phylogenetic analysis suggests that cyanamide is present in V. benghalensis, which is placed in a monophyletic group with cyanamide-biosynthesizing plants, V. villosa and V. cracca; this suggestion was verified.
