Wheat Seedling Metabolomics and Physiology Under Drought Stress with Potassium Treatments

A dataset from a controlled experiment on wheat (Triticum aestivum L.) seedlings under simulated drought stress. The data includes measurements of biomass, photosynthetic performance, antioxidant systems, osmoregulation, and metabolomic profiles for five different treatment groups. The dataset was created by Mingxia Zhang and last updated on 2026-03-18.

Use Cases

• Compare the efficacy of different potassium application methods (chelated vs. mixed) based on biomass and chlorophyll content data.
• Analyze metabolic pathway enrichment (e.g., α-linolenic acid metabolism, plant hormone signal transduction) in response to drought stress treatments.
• Model the relationship between antioxidant enzyme activity, malondialdehyde content, and drought stress alleviation in wheat.
• Investigate the role of specific differential metabolites like (-)-Jasmonoyl-L-isoleucine and (+)-Abscisic acid in drought response.

Strengths

• Includes metabolomic analysis identifying 51 differential metabolites across treatment comparisons.
• Reports specific quantitative results, such as a 15.66% increase in aboveground biomass for one treatment.
• Experimental design includes five distinct treatment groups and a control for comparative analysis.

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 small (269.0 KB), indicating a limited experimental scope.
