Other claims from this paper (16)
- Intervention effect Ammonium at 25% or more of total nitrogen decreased bell pepper leaf dry mass.
- Intervention effect Supplementary calcium ameliorated the decline in bell pepper leaf dry mass.
- Intervention effect Increasing ammonium decreased root hydraulic conductance in bell pepper.
- Intervention effect Increasing ammonium decreased root water content in bell pepper.
- Intervention effect Supplementary calcium mitigated ammonium-induced reductions in root hydraulic conductance.
- Mechanism Ammonium increased bell pepper cell membrane damage through lipid peroxidation.
- Mechanism Ammonium-induced membrane damage increased electrolyte leakage.
- Intervention effect Supplementary calcium did not reduce lipid peroxidation.
- Intervention effect Supplementary calcium increased electrolyte leakage.
- Observation Ammonium-treated bell pepper accumulated a low concentration in roots and high concentration in leaves of an unreadable formula entity.
- Mechanism The high leaf concentration in ammonium-treated bell pepper was attributed to high nitrate reductase activity.
- Intervention effect Ammonium nutrition depressed uptake of potassium, calcium and magnesium.
- Intervention effect Ammonium nutrition increased phosphorus uptake.
- Intervention effect Ammonium increased antioxidant enzyme activity in bell pepper.
- Mechanism Supplementary calcium partially restored bell pepper leaf growth by improving root hydraulic conductance and water relations.
- Recommendation The authors suggest supplementary calcium to increase tolerance to ammonium fertilization.
