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 δ¹⁵N. 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.
