The relationship between N2O emission from wheat leaves (pmol N2O-N m−2⋅s−1) and (A) the change in assimilatory quotient (ΔAQ) when the nitrogen source was shifted from 15NH to 15NO
, or (B) N2O production in the rhizosphere (pmol N2O-N g−1⋅s−1). Shown are the regression lines and the R2 statistic. The rates of N2O emission were normalized by using the log10 transformation.
