Other claims from this paper (9)
- Intervention effect After acetylene assay exposure, Frankia symbiosis nodules evolved large amounts of hydrogen in air.
- Intervention effect Acetylene treatment increased Alnus incana root hydrogen evolution for several days.
- Observation Alnus incana uptake hydrogenase recovered fully in 4 to 8 days.
- Intervention effect Hydrogenase activity in treated Alnus incana nodules was 10% of untreated nodules.
- Intervention effect Three actinorhizal species including Alnus rubra had complete hydrogenase inactivation after assay.
- Observation Hydrogen evolution in Ar/O2 equaled the reduction rate in the complete inactivation group.
- Intervention effect Ceanothus americanus symbiosis showed no change after acetylene assay.
- Intervention effect Batista glomerata symbiosis showed no change after acetylene assay.
- Observation A third group of actinorhizal symbioses had an intermediate assay response.
