From: NH4+-N alleviates iron deficiency in rice seedlings under calcareous conditions
Relationship between root porosity and xylem sap flow rate of rice growing in solutions supplied with NH4+-N (AN (a)) or NO3−-N (NN (b)) as the N source and buffered at high pH (7.5) during low EDTA-Fe supplied for 18 days (‘Experiment 2’). Filled triangles and filled circles represent T43 and T04, respectively. Lines represent linear regressions. “*” or “ns”: significant at p < 0.05 or p > 0.5.
