title: N(2) fixation and h(2) evolution by six species of tropical leguminous trees.
abstract: The C(2)H(4)/(15)N(2) and H(2)/(15)N(2) ratios for six species of tropical leguminous trees are reported. C(2)H(4)/(15)N(2) ratios ranged from 2.4 to 4.7; values for the H(2)/(15)N(2) ratios were between 0.6 and 1.4. Relative efficiency values, based on C(2)H(2) reduction, (15)N incorporation, and H(2) evolution during (15)N incorporation varied between 0.68 and 0.84 for the six species. Overall, approximately 30% of the electron flow through nitrogenase was used for H(2) evolution.
