Spinach Growth and Chromium Content Under Melatonin Priming Treatments

Melatonin seed priming at 50 micromolar concentration increased leaf count by 40% and reduced leaf chromium content by 42.9% in spinach plants under stress. The dataset includes measurements of seedling growth, leaf area, chlorophyll index, and chromium content from controlled and polyhouse experiments. M. Sowhnthariya published this data on figshare in 2026.

Use Cases

• Modeling the relationship between melatonin concentration and chromium uptake reduction based on atomic absorption spectroscopy results.
• Analyzing plant growth performance under heavy metal stress using metrics like leaf number and leaf area.
• Investigating spectral stress signatures based on the described 512–515 cm⁻¹ band variations.
• Comparing treatment efficacy between controlled seedling conditions and polyhouse field-grown plants.

Strengths

• Includes specific, quantified results such as a 42.9% reduction in leaf chromium content and a 78% improvement in chlorophyll index.
• Data covers both controlled seedling experiments and polyhouse field conditions, allowing for comparison.
• File formats include raw data (XLSX) alongside documentation (DOCX) and supporting images (JPG).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
• The dataset's 538.5 KB size indicates a limited experimental scope, not a large-scale survey.
