Other claims from this paper (11)
- Observation The soybean mutants nodulated more quickly than Bragg under conducive conditions.
- Intervention effect At pH 4.0 and 0.05 mM calcium, nodulation was inhibited in all lines.
- Observation At pH 4.0 and 1.0 mM calcium, only Bragg had inhibited nodulation.
- Observation Nodule number and weight were much greater in the mutants than Bragg, especially at pH 4.5–6.0.
- Intervention effect Shoot and root weights in Bragg and nts 1116 generally increased with solution pH.
- Observation Shoot and root weight of nts 382 fell strongly at pH 5.0 and 6.0, alongside high nodule numbers.
- Observation The mutants nodulated more prolifically than Bragg at 32 μM aluminium activity.
- Observation Mutants failed to nodulate only at 70 μM aluminium activity.
- Observation Bragg failed to nodulate at 32 μM aluminium activity.
- Intervention effect Aluminium activity of 0.1–0.4 μM reduced nodule number and weight by 10%.
- Intervention effect Aluminium activity of 5–10 μM was required to reduce shoot weight by 10%.
