Abstract:
The herbicide metsulfuron-methyl reduced nitrate assimilation and nitrate concentrations in soybean (Glycine max L.). The results were interpreted in comparison with time series of two-dimensional tracer images in leaves obtained in vivo from the positron-emitting tracer imaging system (PETIS) after application of 13N-nitrate to cut stems.
