| Abstract: | The preliminary results with detached leaves and seedlings of corn, soybean and sorghumfrom pot and field experiments indicate that inorganic nitrogen supply can significantly enhance the N2O emission and NO3- concentration in plants in the case of phosphorus deficiency and of less light, but phosphorus Supply and sunlight condition can markedly reduce the N2O emission and NO3- concentration in the plants.It's concluded seemed thatthe N2O emission is a kind of physiological protection to avoid NO3- accumulation in plantswhen nitrogen metabolism in plants is in disorder and mineral nitrogen is in over supply. |
