Soybean Root Morphology and Hydraulic Responses Under Sequential Salt Stress

Root trait data from hydroponic experiments on three near-isogenic soybean lines with contrasting salt tolerance alleles. The dataset includes TIF and DOCX files measuring root dry weight, volume, lateral root number, surface area, and hydraulic resistance under varying salt concentrations. Authored by Qiuzhi Rui and last updated on 2026-05-08.

Use Cases

• Modeling the relationship between root morphological traits and salt tolerance based on measurements of lateral root number and surface area.
• Analyzing trade-offs between root growth and stress resistance based on interactions observed for root dry weight and volume.
• Comparing hydraulic transport properties between genotypes based on measurements of xylem sap exudation and hydraulic resistance.

Strengths

• Dataset is focused on a specific physiological mechanism, comparing three genetically defined near-isogenic lines.
• Includes measurements of multiple root traits such as dry weight, volume, lateral root number, and surface area under sequential salt conditions.
• Released under a permissive CC-BY-4.0 license, allowing for broad reuse.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset is small at 1.0 MB, suggesting a limited observational scale.
• Description metadata is limited; actual data quality requires manual inspection after download.
