Cold Tolerance in 16 Red Prickly Ash Germplasms with Physiological Indices

Sixteen red prickly ash germplasms were subjected to low-temperature treatments at 0, -10, -20, and -30 °C. The dataset, authored by Yuping Wang and last updated in 2026, contains physiological measurements including relative conductivity, soluble sugar, soluble protein, free proline, and antioxidant enzyme activities. It identifies germplasms with strong and weak cold tolerance based on comprehensive membership function scores and principal component analysis.

Use Cases

• Classifying plant germplasm cold tolerance based on physiological indices like relative conductivity and semi-lethal temperature.
• Modeling the relationship between temperature stress and biochemical markers such as soluble sugar, soluble protein, and free proline.
• Screening for resilient plant varieties using principal component analysis scores derived from multiple physiological measurements.

Strengths

• Includes data for 16 distinct germplasm lines, enabling comparative analysis.
• Measures physiological responses across four specific temperature points (0, -10, -20, -30 °C).
• Reports specific semi-lethal temperature results for named germplasms like WCDHP, CCSJ, and HGHJ.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is contained within a 251.6 KB PDF file, which is a very small and potentially limited scope.
