Other claims from this paper (11)
- Intervention effect Al reduced nitrate uptake in both cultivars, particularly the sensitive one.
- Intervention effect Al decreased Vmax by 98% in the sensitive cultivar.
- Intervention effect Al increased Km by 267% in the sensitive cultivar.
- Intervention effect Al increased Km by 42% in the tolerant cultivar.
- Intervention effect Al reduced root and shoot NR activity, especially in the sensitive cultivar.
- Intervention effect Al applied in nutrient solution and reaction mixture inhibited root and shoot NR differently.
- Intervention effect Al reduced shoot NR Vmax.
- Intervention effect Al did not affect shoot NR Km.
- Mechanism Authors interpret Al inhibition of NR as noncompetitive and irreversible by extra nitrate.
- Mechanism Al had a direct effect on NR and nitrate reduction.
- Association NR tolerance to Al correlated with plant tolerance to Al.
