Other claims from this paper (12)
- Observation Acetylene reduction by soybean nodules began without a lag and stayed linear for about 80 minutes.
- Intervention effect Evacuation caused no apparent injury to soybean nodules.
- Association Acetylene reduction rates rose with pO 2 up to 1 atm.
- Observation Respiration did not seriously deplete available oxygen when nodules occupied under 20% of bottle volume.
- Observation About 0.2 atm acetylene gave the fastest acetylene reduction.
- Observation Nodules 3–5 mm in diameter were most active.
- Observation Intact soybean plants, nodulated roots and detached nodules fixed nitrogen at relative rates near 100/46/23.
- Association Soybean acetylene reduction showed a diurnal cycle dependent on light intensity.
- Association Soybean acetylene reduction showed a diurnal cycle dependent on air temperature.
- Observation The observed acetylene-to-nitrogen reduction ratio was approximately 2.0 versus a theoretical 3.0.
- Observation Soybean varieties differed dramatically in the onset and termination dates of acetylene reduction.
- Intervention effect Plants inoculated with a mixture of effective Rhizobium japonicum strains had the most vigorous acetylene reduction.
