Stable isotopes of nitrogen (N) in plants are increasingly used to evaluate ecosystem N cycling patterns. A basic assumption in this research is that plant dN reflects the dN of the N source. Recent evidence suggests that plants may fractionate on uptake, transport, or transformation of N. If the dominant source of plant N is via roots, a difference in dN by tissue type would suggest fractionation on transport and assimilation of N. In order to evaluate differences between species and plant… CONTINUE READING
