title: Effects of region, genotype, harvest year and their interactions on δ13C, δ15N and δD in wheat kernels.
abstract: The objective of this study was to investigate the influences of region, genotype, harvest year and their interactions on stable carbon, nitrogen and hydrogen isotopic ratio (δ(13)C, δ(15)N and δD) fingerprints in wheat kernels. A total of 270 wheat kernel samples including ten genotypes were collected from three different regions of China during 2011-2013 harvest. Analysis of variance was employed to investigate the effects of region, genotype, harvest year and their interactions on the δ(13)C, δ(15)N and δD. The results showed that the δ(13)C and δ(15)N values in wheat kernels were significantly influenced by the region, genotype, harvest year and their interactions (region × genotype, genotype × year, region × year and region × genotype × year), δD was significantly affected by region, genotype, harvest year and region × year. Region accounted for the largest proportion of the total variation and explained 47.57%, 58.02% and 27.96% for δ(13)C, δ(15)N and δD, respectively.
