Pretreatment with 0.2 rather than 3.0 mol m−3 nitrate produced about twofold higher maximum influx at day end.

Other claims from this paper (7)
- Observation Tomato nitrate influx kinetics showed multiphasic patterns.
- Method / resource Three non-additive Michaelis-Menten kinetics best fit the nitrate influx data, with transitions near 0.8 and 4 mol m−3.
- Intervention effect Maximum influx rate declined during the night through 24 hours of darkness in plants grown at 3.0 mol m−3 nitrate.
- Association Nitrate influx rates at any solution nitrate concentration were negatively correlated with plant nitrate concentration.
- Association Maximum influx rate in every phase was negatively correlated with plant nitrate concentration.
- Observation The authors inferred a plant nitrate set point near 66 mol m−3 at which influx is null.
- Method / resource A modified Michaelis-Menten model was proposed to predict nitrate influx from solution and plant nitrate concentrations.
