RESUMO
Differences among plant parts in the natural abundance of 15N are of interest from the point of view of developing a sampling strategy for using 15N measurements to estimate the contribution of symbiotically fixed N to N2 fixing plants, and because they reflect isotopic fractionation associated with degradation, transport, and resynthesis of N-bearing molecules. This paper reports such differences in nodulating and nonnodulating isolines of soybeans (Glycine max [L] (Merrill, variety Harosoy)) grown under several different conditions.
