Other claims from this paper (10)
- Observation Field vines on low phosphorus soil had magnesium deficiency symptoms and low leaf phosphorus and magnesium.
- Intervention effect Phosphorus fertilizer increased leaf phosphorus and magnesium concentrations above critical levels.
- Intervention effect Foliar magnesium raised leaf magnesium above critical levels.
- Intervention effect Foliar magnesium did not significantly change leaf phosphorus.
- Intervention effect Nutrient applications increased photosynthesis above 1.0 nmol CO 2 cm 2 s 1 from approximately 0.7 in controls.
- Observation Magnesium in large roots without phosphorus was approximately twice that with phosphorus.
- Observation Xylem sap magnesium concentration with phosphorus was twice that without phosphorus.
- Intervention effect Supplying phosphorus to deficient vines raised magnesium concentration to that of phosphorus supplied vines within 2 days.
- Mechanism Magnesium translocation from roots to shoots depends on phosphorus supply to roots.
- Association Magnesium translocation may be more sensitive to phosphorus supply than uptake.
