Relative Abundance of Ureides and Nitrate in Plant Tissues of Soybean as a Quantitative Assay of Nitrogen Fixation

The relationship between the relative abundance of ureides ([ureide-N/ureide-N plus nitrate-N] x 100) in the shoot axis (stems plus petioles), nodulated roots and leaflets of "Bragg" soybean (Glycine max [L.] Merrill) and the symbiotic dependence of these plants was examined under glass-house condit...
