Heat Tolerance of 36 Oncidium Orchid Cultivars with Physiological Biomarkers

Xiaoyan Luo's research dataset evaluates the heat tolerance of 36 Oncidium orchid cultivars through field and controlled environment screening. It identifies 8 highly heat-tolerant cultivars, a discriminative temperature threshold of 40.00°C, and core physiological biomarkers including relative electrolyte conductivity and proline content. The dataset was last updated on May 22, 2026.

Use Cases

• Screening orchid cultivars for heat tolerance based on identified physiological biomarkers like relative electrolyte conductivity and proline content.
• Validating breeding strategies by analyzing the relationship between membrane stability, osmotic adjustment, and heat adaptation.
• Benchmarking new Oncidium varieties against the 8 identified heat-tolerant cultivars from this study.

Strengths

• Includes data from 36 distinct Oncidium cultivars, enabling comparative analysis.
• Identifies a specific discriminative temperature threshold of 40.00°C for heat tolerance screening.
• Confirms three core physiological biomarkers with a coefficient of variation greater than 50.00%.

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 very small at 13.0 KB, indicating limited scope, likely a summary document rather than raw experimental data.
