摘要: 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 (delta C-13, delta N-15 and delta D) 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 delta C-13, delta N-15 and delta D. The results showed that the delta C-13 and delta N-15 values in wheat kernels were significantly influenced by the region, genotype, harvest year and their interactions (region x genotype, genotype x year, region x year and region x genotype x year), delta D was significantly affected by region, genotype, harvest year and region x year. Region accounted for the largest proportion of the total variation and explained 47.57%, 58.02% and 27.96% for delta C-13, delta N-15 and delta D, respectively. (C) 2014 Elsevier Ltd.
