Wheat Grain Elemental Concentrations for EDXRF Method Calibration

Elemental concentration measurements for calcium, manganese, iron, copper, and zinc in wheat grain samples from diverse genotypes. The data includes values from both energy-dispersive X-ray fluorescence (EDXRF) and microwave plasma–atomic emission spectrometer (MP-AES) reference methods. It was authored by Emily Klarquist and last updated on 2026-04-22.

Use Cases

• Calibrating and validating non-destructive EDXRF methods based on paired MP-AES reference measurements.
• Comparative assessment of analytical methods for elemental concentration in plant tissues.
• Studying genetic variation in grain nutrient content for biofortification research.
• Developing predictive models for nutrient phenotyping in wheat breeding programs.

Strengths

• Includes paired measurements from two analytical methods (EDXRF and MP-AES) for direct comparison.
• Data is organized by genotype, sample group (calibration/validation), and method, facilitating structured analysis.
• Released under a permissive CC0-1.0 license for unrestricted reuse.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset size is listed as 0.0 B, indicating a very limited scope or potential metadata issue.
