Other claims from this paper (5)
- Observation Metals varied in how quickly cowpea root elongation was reduced.
- Intervention effect A range of metals ruptured the rhizodermis and outer cortex in cowpea root elongation and transition zones within 2 – 24 h.
- Association All metals causing root tissue rupture were highly rhizotoxic, while some highly rhizotoxic metals did not cause rupture.
- Mechanism The authors infer that metal rhizotoxicity involves disruption of multiple biochemical mechanisms in cowpea.
- Observation No tested metal served as a full analogue of another for cowpea root toxicity.
