- Intervention effect Severe Mn deficiency depressed top dry weight, photosynthesis and chlorophyll concentration.
- Intervention effect Severe Mn deficiency did not affect transpiration.
- Intervention effect Mild Mn toxicity did not reduce photosynthesis, chlorophyll concentration or transpiration.
- Observation Critical Mn deficiency for top dry weight was 0.23 mmol kg −1.
- Observation Critical Mn deficiency for apparent photosynthesis was 0.30 mmol kg −1.
- Observation The minimum Mn requirement for chlorophyll was 0.14 mmol kg −1, about half that for top production.
- Observation The critical Mn toxicity level for top dry weight was 7 mmol kg −1.
- Observation Photosynthesis was depressed at a Mn concentration of 19 mmol kg −1.
- Observation Chlorophyll concentration was depressed at a Mn concentration of 19 mmol kg −1.
- Observation Transpiration was depressed at a Mn concentration of 24 mmol kg −1.
- Recommendation Maximum wheat growth and yield are expected at blade 1 Mn concentrations of 0.23 to 7 mmol kg −1.
