Root hydraulic conductance (a), root water uptake rates during daytime (b) and leaf water potential (c) of rice growing in solutions supplied with NH4+-N (AN) or NO3−-N (NN) as the N source and buffered at high pH (7.5) during low EDTA-Fe(II) supplied for 18 days (‘Experiment 2’). Error bars represent SE (n = 3). The bar graph line within each cultivar the same letter are not significantly different at 5% according to Duncan’s multiple range tests.
