Other claims from this paper (9)
- Intervention effect Cobalt significantly decreased chlorophyll in all tested cultivars.
- Intervention effect Cobalt significantly decreased foliar iron in all tested cultivars.
- Intervention effect Cobalt significantly increased foliar and root cobalt in all tested cultivars.
- Intervention effect Cobalt effects on root iron varied among cultivars.
- Observation Iron-inefficient cultivars were most susceptible to chlorosis with cobalt and apparently truly iron deficient.
- Association Chlorophyll formation was generally limited below 50 ug Fe g–1 dry weight foliar iron regardless of cobalt treatment.
- Association Efficient cultivars apparently did not excrete reductant or protons at cobalt levels where iron uptake limited chlorophyll formation.
- Observation Iron-efficient cultivars appeared to remain efficient at low cobalt levels despite absent outward indicators.
- Observation The iron-stress response mechanism was not observed in iron-inefficient cultivars at any cobalt level.
