Supplementary file 1_Spatiotemporal response of photosynthetic characteristics in Epimediu

8.4 MB of data on the spatiotemporal photosynthetic characteristics of Epimedium pubescens, a traditional Chinese medicine plant, across three artificial forest types. The study, authored by Doudou Li and last updated in May 2026, monitored net photosynthetic rate and stomatal conductance at different planting positions from April to December. Results indicate solar radiation was the primary driver of photosynthetic rate, with an independent explanatory rate of 34.3% at the seasonal scale.

Use Cases

• Modeling the impact of solar radiation on photosynthetic rate based on diurnal and seasonal measurements.
• Comparing stomatal conductance regulation by vapor pressure deficit and air humidity across different forest stands.
• Analyzing spatial variation in plant physiology between inter-row and under-canopy planting positions.
• Investigating canopy light transmittance for precision cultivation of shade-tolerant crops.

Strengths

• Data includes measurements across a 9-month growing season from April to December.
• Analysis covers three distinct artificial forest types (Phellodendron amurense, Phoebe zhennan, Camptotheca acuminata).
• Results are supported by statistical models, including variance decomposition and structural equation modeling with reported R² values.

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 stored in a DOCX file, which may require extraction or conversion for analysis.
