Using stable isotope natural abundances (delta 15N and delta 13C) to integrate the stress responses of wild barley (Hordeum spontaneum C. Koch.) genotypes.

Abstract excerpt

To integrate the complex physiological responses of plants to stress, natural abundances (delta) of the stable isotope pairs 15N/14N and 13C/12C were measured in 30 genotypes of wild barley (Hordeum spontaneum C. Koch.). These accessions, originating from ecologically diverse sites, were grown in a controlled environment and subjected to mild, short-term drought or N-starvation. Increases in total dry weight were...
