Table 1_Growth-stage dependent changes of leaf chlorophyll content as a proxy for photosyn

Weekly measurements of leaf nitrogen, chlorophyll, and carotenoid contents, plus photosynthetic capacity parameters, for a summer maize cropland in North China from the tillering stage to maturity. The dataset, authored by Wenjing Wang and last updated in March 2026, likely contains tabular data exploring the growth-stage dependent relationships between leaf biochemistry and photosynthetic capacity in a C4 crop. It is a small dataset, approximately 676 KB in size.

Use Cases

• Modeling the relationship between leaf chlorophyll content and maximum carboxylation rate (Vcmax25) based on the reported R² values.
• Analyzing growth-stage dependency in photosynthetic proxies by comparing pre- and post-flowering correlations.
• Developing regression models to estimate Vcmax25 using combined leaf N, Chl, and Car content as described in the multiple linear regression analysis.
• Investigating the comparative explanatory power of leaf chlorophyll versus leaf nitrogen for photosynthetic capacity in C4 crops.

Strengths

• Includes specific correlation metrics (e.g., R² = 0.81 between Vcmax25 and Chlarea pre-flowering) that validate the data's utility.
• Covers multiple key physiological variables (leaf N, Chl, Car, Vpmax, Vcmax, Jmax) measured weekly across the plant's growth cycle.
• Provides clear geographical and temporal context: data is from a summer maize cropland in North China, measured from tillering to maturity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (676.3 KB), indicating a limited scope likely focused on a specific study site and season.
