[Effects of illumination, carbon source and reducing power on N2O emission from maize and soybean seedlings].
The closed chamber measurement of N2O emission from soybean and maize seedlings showed that there were two peaks (10:30 and 14:30) of N2O flux at the daytime. There was a correlation between N2O emission and illumination. The variation of illumination had a significant influence on N2O flux from soybean and maize seedlings. There was a positive correlation between N2O emission and illumination when the illumination was below 11,345 Lx (for soybean, R2 = 0.7332) or 2,000 Lx (for maize, R2 = 0.8711), and a negative correlation when the illumination was over 11,345 Lx (for soybean, R2 = 0.7755) or 20,000 Lx (for maize, R2 = 0.8972). Addition of carbon source (glucose) and NADH (reducing power) decreased N2O flux.
