Other claims from this paper (7)
- Intervention effect Foliage and storage root dry weights of sweetpotato declined linearly with increasing Mn concentration in whole plants.
- Observation Foliage dry weight showed a more moderate decrease than storage root growth.
- Observation Mn concentration was higher in sweetpotato foliage than in fibrous roots.
- Intervention effect Sweetpotato roots showed browning at the higher Mn concentrations (10 or 100 mg/liter) in solution.
- Intervention effect Characteristic Mn toxicity symptoms were observed in plants receiving 2.5, 10 or 100 mg/liter Mn in solution.
- Observation A Mn concentration of approximately 1000 ug/g in whole sweetpotato plants is a critical concentration with respect to Mn toxicity.
- Observation A Mn concentration of approximately 100 ug/g in fibrous roots is a critical concentration with respect to Mn toxicity in sweetpotato.
