Other claims from this paper (8)
- Intervention effect Calcium deficiency caused necrosis of apical buds.
- Intervention effect Calcium deficiency retarded the development of each leaf.
- Intervention effect Phosphorus deficiency markedly reduced photosynthetic activity per unit leaf area.
- Intervention effect Phosphorus deficiency decreased respiratory activity of each organ.
- Intervention effect Calcium deficiency had no such effect on photosynthesis per unit leaf area.
- Intervention effect Calcium deficiency considerably decreased photosynthesis per unit dry weight.
- Mechanism The decrease in growth caused by phosphorus deficiency is explained by dry matter production.
- Observation Phosphate and calcium ion effects on plant growth depend on the whole amount available to the plant rather than on concentration.
