Other claims from this paper (10)
- Intervention effect Low applied phosphorus lowered wheat growth rates relative to high phosphorus.
- Intervention effect Phosphorus deficiency increased insoluble phosphatase activity in mature wheat leaves.
- Intervention effect Phosphorus deficiency increased soluble phosphatase activity in mature wheat leaves.
- Association Soluble phosphatase activity rose 2.5–3.0 fold as wheat leaf phosphate concentration fell from 0.4% to 0.1% dry weight.
- Intervention effect Severe nitrogen deficiency did not change wheat phosphatase activity.
- Observation Soluble phosphatase activity was higher in young than mature wheat leaves.
- Intervention effect Severe water deficit increased soluble phosphatase activity 3–4 fold in wheat leaves.
- Observation Increased soluble phosphatase activity under water deficit was not accompanied by low phosphate concentration in wheat leaves.
- Intervention effect After rewatering, soluble phosphatase activity rapidly decreased in mature leaves of water-deficient wheat.
- Observation High soluble phosphatase activity persisted for up to 12 d after phosphorus resupply in mature leaves of phosphorus-deficient wheat.
