| 英文摘要 | The emission of N2O from soybean plants treated with the herbicides dichlorophenoxyacetic acid (2,4-D) and bromoxynil was studied. The N2O flux from 2,4-D- and bromoxynil-treated soybean was 14.1 ng N2O-N g(-1) fresh weight h(-1) and 19.7 ng N2O-N g(-1) fresh weight h(-1), respectively, i.e. approximately twice that of the controls. The NO2--N concentration in 2,4-D- and in bromoxynil-treated soybean was about 8 mug N g(-1) fresh weight, i.e. fivefold the concentration found in control plants. The NO3- content in herbicide-treated soybean did not differ significantly from that of the control plants. Consequently, the accumulation of NO2--N during the assimilation of NO3--N was thought to cause the observed N2O release. Probably, N2O is a by-product produced during either the reaction of NO2--N with plant metabolites or NO2--N decomposition. Final conclusions must await further experiments. |
