Maize Seedling Growth Data Under Salt Stress with PGPR Inoculation

Experimental data from a pot study investigating the growth-promoting effects of the rhizobacteria strain Enterobacter asburiae PW2 on the maize variety 'Ningdan 33' under salt stress. The dataset, authored by Mengyuan Wen and last updated in May 2026, likely contains measurements of plant height, root length, biomass, and biochemical markers such as antioxidant enzyme activities and osmolyte contents. Results show significant increases in plant growth metrics and antioxidant enzyme activities, with decreases in oxidative damage markers.

Use Cases

• Modeling the relationship between PGPR inoculation and maize seedling growth metrics under salt stress.
• Analyzing the effect of bacterial strain PW2 on antioxidant enzyme activity (POD, SOD, CAT) and oxidative damage (MDA) in plant tissues.
• Investigating correlations between bacterial traits (nitrogen fixation, IAA synthesis) and improvements in plant osmotic regulation (soluble sugar, protein, proline).

Strengths

• Includes specific, statistically significant results (e.g., POD activity increased by 92.75% with p=4.0×10^-7).
• Describes multiple measured plant growth and stress response variables, such as fresh/dry weights and biochemical contents.
• The bacterial strain is characterized with specific salt and pH tolerance ranges (2.0%-10.0% NaCl, pH 8.0-11.0).

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 (21.9 KB), indicating a limited scope, likely a single experiment's results.
