Other claims from this paper (8)
- Intervention effect Ureide treatment almost completely inhibited acetylene reduction activity within 4 to 7 days.
- Intervention effect Ureide treatment increased shoot ureide concentration.
- Intervention effect Ureide concentration did not increase in nodules following treatment.
- Association Inhibition of acetylene reduction depended on applied ureide concentration.
- Intervention effect Urea inhibited acetylene reduction activity.
- Intervention effect Asparagine caused the greatest inhibition of nodule activity.
- Mechanism Authors infer ureides act through a derivative rather than directly on nodules, with asparagine a candidate.
- Intervention effect Ureide treatment continually decreased nodule oxygen permeability over five days.
