Salt stress increases the respiratory cost of nitrogen fixation

The effects of NaCl stress (0, 3,000, 6,000 ppm) on the nitrogen ixation, respiration, and respiratory cost of nitrogen fixation of detached alfalfa nodules were investigated. Acetylene reduction activity and respiration of the nodules decreased to 96 and 84% of the control at 3,000 ppm NaCl, and to...
