Heat Tolerance Measurements for 36 Oncidium Orchid Cultivars

36 Oncidium orchid cultivars were screened for heat tolerance, identifying 8 highly tolerant varieties. The study determined 40.00°C as the optimal discriminative temperature and identified relative electrolyte conductivity, proline content, and peroxidase activity as core physiological biomarkers. This dataset was authored by Xiaoyan Luo and published on figshare in May 2026.

Use Cases

• Rank cultivars for heat tolerance based on physiological biomarker measurements
• Model the relationship between membrane stability and osmotic adjustment in heat adaptation
• Validate screening protocols using the identified 40.00°C discriminative temperature
• Investigate proline accumulation patterns as indicators of passive damage versus active protection

Strengths

• Includes data from 36 distinct Oncidium cultivars, enabling comparative analysis
• Identifies three core biomarkers with a coefficient of variation exceeding 50.00%
• Principal component analysis explains 80.95% of variance in heat adaptation

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 very small (15.7 KB), indicating limited scope
