White Spruce Bud Set, Frost Tolerance, and Carbohydrate Data from Climate-Contrasted Sites

Supplementary file 1 contains data on bud set phenology, autumn frost tolerance, and non-structural carbohydrate concentrations for six white spruce seed sources. The data was collected in 2021 from two test sites in Quebec, Canada, with contrasting climates, as part of a study authored by Chafik Analy. The dataset was last updated on April 28, 2026.

Use Cases

• Modeling bud set timing based on seed source and site latitude.
• Assessing autumn frost damage risk based on measured needle tissue damage thresholds.
• Analyzing seasonal non-structural carbohydrate dynamics (fructose, glucose, sucrose, pinitol) in relation to temperature.
• Evaluating seed source performance for assisted migration planning under climate change.

Strengths

• Data is derived from a controlled study evaluating six geographically distinct seed sources.
• Measurements include multiple variables: phenological stages, frost tolerance, and four specific carbohydrate types.
• Data collection occurred at two climatically contrasted test sites, allowing for comparative analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (3.6 MB), potentially limiting the scope of analysis.
