Citation

Leroy H Wullstein, Variation in N 2 Fixation (C 2 H 2 Reduction) Associated with Rhizosheaths of Indian Ricegrass (Stipa hymenoides): .

Summary

Relatively low but significant rates of N2 fixation (C2H2 reduction) associated with rhizosheaths of Indian ricegrass Stipa hymenoides varied inversely with percent O2 in test atmospheres, and directly with percent water-holding capacity of sand substrate. Nitrogen fixation was not observed for plants tested in late summer or for nonrhizosheath plants inhabiting nonsandy soil. Delayed linear rates of C2H2 reduction preceded by ca. 24-48 h lag periods were observed. Published in American Midland Naturalist, volume 126, issue 1, on pages 76 - 81, in 1991.
