Other claims from this paper (8)
- Intervention effect Increasing nitrate levels increased root uptake of nitrate in spinach.
- Intervention effect Increasing nitrate levels increased leaf nitrate reductase and glutamine synthetase activities in spinach.
- Association Leaf oxalate accumulation in spinach is positively related with nitrate uptake by roots and with leaf NR and GS activities.
- Intervention effect Sodium vanadate, a plasmalemma H(+)-ATPase inhibitor, significantly decreased leaf oxalate accumulation in spinach.
- Intervention effect NR or GS inhibitors reduced leaf oxalate contents in spinach.
- Intervention effect NR or GS inhibitors decreased nitrate uptake rate in spinach.
- Intervention effect NR or GS inhibitors reduced GS/NR activities in spinach.
- Observation The high-oxalate genotype Heizhenzhu had higher nitrate root uptake and leaf NR and GS activities than Weilv.
