Other claims from this paper (6)
- Observation Linear zinc uptake by excised barley roots over 20–120 minutes did not persist over 20–28 hours.
- Observation Zinc uptake by intact barley roots had three concentration-dependent phases up to 1.38 m M zinc across tested uptake periods.
- Association Kinetic constants increased in higher uptake phases.
- Association Transition points declined as uptake time increased.
- Intervention effect Copper slightly stimulated zinc uptake rates.
- Mechanism The authors concluded that zinc and copper use separate uptake mechanisms.
