From: NH4+-N alleviates iron deficiency in rice seedlings under calcareous conditions

Phenotypes of the first fully expend leaf (a,b), leaf chlorophyll content in shoots (c) and biomass of rice (d,e) growing in solutions supplied with NH4+-N (AN) or NO3−-N (NN) as the N source and buffered at high pH (7.5) during Fe-deficient for 3, 6 and 12 days (‘Experiment 1’). 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.
