Metabolomic Profiles of Flue-Cured Tobacco Leaves Across Maturity Stages in Guizhou, China

Guizhou Province, China, is the geographic scope of this dataset. It contains metabolomic and physiological measurements from flue-cured tobacco leaves at different maturity stages, collected from two distinct ecological regions. The data includes sensory style scores, enzyme activities, and environmental variables, compiled by Chenyu Cai and last updated in May 2026.

Use Cases

• Modeling the relationship between leaf maturity and sensory style characteristics based on sensory evaluation scores.
• Analyzing region-specific metabolic patterns in response to environmental variables based on radiation, temperature, precipitation, and soil data.
• Investigating transcriptional-metabolite coupling in flavonoid and sugar metabolism pathways based on RT-qPCR validation data.
• Comparing physiological changes like SPAD values and enzyme activities across different harvest times.

Strengths

• Includes data from two distinct ecological regions (Dafang and Weining Counties) representing honey-sweet and fresh-sweet flavor profiles.
• Measures multiple data types: 72 differential metabolites identified in one region and 51 in another, alongside enzyme activities, sensory scores, and environmental variables.
• Covers five distinct maturity stages (16, 18, 20, 22, and 24 days after topping) for phenotypic and physiological traits.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The metabolomic analysis was performed only on cured leaves from the earliest (T1) and latest (T5) maturity stages, not all five stages.
