<b>Species-specific antioxidant coordination drives photosynthetic recovery from recurrent

Data collected before, during, and after simulated heatwave events on two-year-old seedlings of Schima superba and Phoebe bournei. The dataset includes measurements of gas exchange, chlorophyll fluorescence, antioxidant systems, and microclimatic variables, collected in Fujian Province, China. Statistical analyses were performed using R software (version 4.3.1).

Use Cases

• Modeling the relationship between recovery intervals and stress memory based on repeated heatwave experiments.
• Comparing photosynthetic efficiency (Pn, Fv/Fm) and water use efficiency (WUE) between Schima superba and Phoebe bournei under heat stress.
• Analyzing correlations between antioxidant enzyme activity (SOD, POD, CAT) and oxidative damage (MDA) during heat stress and recovery.
• Investigating the impact of microclimatic variables (air temperature, VPD, SWC) on physiological parameters across different heatwave frequencies.

Strengths

• Includes multiple physiological measurement types (gas exchange, chlorophyll fluorescence, antioxidant systems) for integrated analysis.
• Data collected across a controlled experimental timeline (before, during, and after heatwaves) with varying recovery intervals (7, 15, 23 days).
• Uses specific, uniform plant material (two-year-old seedlings selected for uniform growth and health).
• Statistical analysis methods (PLS-PM, SEM, Pearson correlation, Mantel tests) are explicitly stated.

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 is small (119.2 KB), indicating a limited experimental scope.
