Translocation and utilization of nitrogen by pulses

Enhancing crop legume N2 fixation through selection and breeding

“…Not all legumes export fixed N2 as ureides (Table 3). With the cool season food legumes, around 80% of fixed N2 is exported from the nodules as the amides, asparagine and glutamine, the remainder as amino acids (Herridge et al, 1988b). It would be extremely useful though to extend the principal of the ureide assay of N2 fixation activity to the amide exporters.…”
