Other claims from this paper (8)
- Observation Developing wheat ears (grains and glumes) are sites of nitrate reduction.
- Intervention effect In a field experiment without N supply, NR activity in glumes and grains did not differ from that of the flag leaf blade.
- Intervention effect Application of N significantly enhanced NR activity of the flag leaf blade but not that of glumes and grains.
- Intervention effect In detached culms, flag leaf blade and glumes both responded to nitrate in the medium.
- Intervention effect Soil N application did not enhance NR activity in grains, and nor did additional nitrate supply to detached culms.
- Intervention effect At high N (180 kg/ha), total NR of the leaf blades was significantly higher than that of the developing ears.
- Intervention effect At low N (0 and 90 kg/ha), total NR activity of the developing ears equalled that of the leaf blades on the main shoot.
- Mechanism Under field conditions, NR appeared to operate at sub-optimal levels in the wheat tissues tested.
