Title

P. Aparicio-Tejo; Manuel Sánchez-Díaz PLANT PHYSIOLOGY 1982. doi:10.1104/pp.69.2.479
Other claims from this paper (9)
- Intervention effect Water stress decreased nitrogen fixation in Medicago sativa.
- Intervention effect Nitrate strongly inhibited nitrogen fixation.
- Intervention effect Leaf NRA recovered with rewatering, especially in nitrate-watered plants.
- Intervention effect Nodular NRA increased with progressing water stress in both nitrate-watered and water-only plants.
- Observation Beyond -15.10(5) pascal, nodular NRA decreased in nitrate-watered plants.
- Observation That late decline in nodular NRA was not observed in plants given only water.
- Intervention effect Rewatering increased nodular NRA in nitrate-watered plants.
- Intervention effect Rewatering decreased nodular NRA in plants not given nitrate.
- Intervention effect Nitrogen fixation increased on rewatering only without nitrate.
