Other claims from this paper (13)
- Intervention effect Aluminum reduced soybean nodule mass and number.
- Mechanism Reduced nodule number was attributed mainly to hydrogen ion toxicity.
- Observation Aluminum had a stronger effect on nodule growth than hydrogen ions.
- Intervention effect Aluminum applied only to lower roots significantly reduced nodulation and nodule growth in upper vermiculite.
- Mechanism The indirect nodulation reduction was attributed mainly to aluminum rather than hydrogen.
- Intervention effect Subsurface aluminum significantly limited root growth where applied.
- Mechanism Abnormal lower root growth may explain indirect nodulation effects.
- Intervention effect High aluminum soil in lower compartment did not reduce upper nodule number or mass.
- Intervention effect In a single compartment, high aluminum soil was more harmful than aluminum solutions to nodulation and growth.
- Intervention effect Subsurface root growth was less affected by high soil aluminum than by aluminum nutrient solution.
- Intervention effect Nodule activity declined only after direct aluminum exposure.
- Association Asparagine/glutamine ratio rose in every aluminum treatment that reduced nodulation.
- Intervention effect Total xylem sap amino acid concentration increased in some aluminum treatments.
