Abstract Given a uniform N source, the δ15N of barley shoots provided a genotypic range within treatments and a separation between control and salt-stress treatments as great as did δ13C*. Plant δ15N has been represented in the literature as a bioassay of external source δ15N and used to infer soil N sources, thus precluding consideration of the plant as a major cause in determining its own 815N. We believe this to be the first report of plant δ15N as a genetic trait. No mechanistic model is needed for use of δ15N as a trait in controlled studies; however, a qualitative model is suggested for further testing.
