Stomatal Traits in 27 Maize Hybrids Released from 1920 to 2022

27 Pioneer maize hybrids released between 1920 and 2022 were evaluated for stomatal traits under controlled conditions. The dataset includes measurements of stomatal density, size, length, width, leaf area, and total stomatal pore area, with correlations to release year and climate proxy variables. It was authored by Memiş Bilgici and uploaded to figshare under a CC-BY-4.0 license.

Use Cases

• Analyze trends in stomatal density and total pore area based on hybrid release year.
• Model relationships between stomatal traits and climate proxy variables like atmospheric CO2 concentration.
• Investigate correlations between stomatal density, size, and leaf area across a century of breeding.
• Compare stomatal characteristics of modern hybrids (2013-2022) versus historical hybrids (1920-2011).

Strengths

• Includes data for 27 distinct maize hybrids spanning over 100 years of breeding history.
• Reports specific quantitative results, such as modern hybrids having a total stomatal pore area of 9.17 × 10^8 µm² leaf⁻¹.
• Provides statistically significant correlations (e.g., r = -0.56 for total pore area vs. release year).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
