Variation of ¹³C and ¹⁵N enrichments in different plant components of labeled winter wheat (Triticum aestivum L.).

ABSTRACT: Information on the homogeneity and distribution of ¹³carbon (¹³C) and nitrogen (¹⁵N) labeling in winter wheat (Triticum aestivum L.) is limited. We conducted a dual labeling experiment to evaluate the variability of ¹³C and ¹⁵N enrichment in aboveground parts of labeled winter wheat plants. Labeling with ¹³C and ¹⁵N was performed on non-nitrogen fertilized (-N) and nitrogen fertilized (+N, 250 kg N ha^-1) plants at the elongation and grain filling stages. Aboveground parts of wheat were destructively sampled at 28 days after labeling. As winter wheat growth progressed, δ ¹³C values of wheat ears increased significantly, whereas those of leaves and stems decreased significantly. A
