Other claims from this paper (7)
- Intervention effect At equivalent concentrations, cobalt induced more chlorosis and necrosis than manganese.
- Observation Chlorotic plants with cobalt or manganese toxicity contained at least as much iron as normal plants.
- Intervention effect At 5 p.p.m. manganese, lower leaves were injured regardless of cobalt supply.
- Intervention effect Cobalt up to 0·01 p.p.m. gradually decreased top-leaf chlorosis at 5 p.p.m. manganese.
- Intervention effect Cobalt up to 0·01 p.p.m. increased dry weight at 5 p.p.m. manganese.
- Intervention effect Cobalt at 0·1 p.p.m. caused severe chlorosis, necrosis, and stunted growth.
- Intervention effect Raising manganese to 5·0 p.p.m. substantially antidoted cobalt toxicity.
