Other claims from this paper (8)
- Intervention effect At 4 mmol·L-1 Ca2+, wheat leaf nitrate reductase activity increased significantly.
- Intervention effect At 8 mmol·L-1 Ca2+, wheat leaf nitrate reductase activity decreased significantly.
- Intervention effect At 2 mmol·L-1 Ca2+, wheat glutamine synthetase activity increased markedly.
- Intervention effect At 8 mmol·L-1 Ca2+, wheat glutamine synthetase activity decreased.
- Intervention effect All applied Ca2+ concentrations increased NADH-GDH activity in wheat leaves.
- Observation Wheat leaves had high nitrogen content at 4 mmol·L-1 Ca2+.
- Mechanism The authors concluded that glutamine synthetase activity was important for wheat nitrogen assimilation.
- Recommendation The authors judged 4 mmol·L-1 Ca2+ most effective for wheat nitrogen assimilation.
