Data Sheet 1_Promotion of maize seedling growth by Enterobacter asburiae PW2 under salt st

Mengyuan Wen's research data sheet, published on figshare in May 2026, details a pot experiment on the maize variety 'Ningdan 33'. The study investigates the salt-tolerant plant growth-promoting rhizobacterium Enterobacter asburiae PW2, isolated from salinized soil in Yinchuan, Ningxia. The 224.4 KB PDF reports significant increases in plant growth metrics and antioxidant enzyme activities under salt stress conditions.

Use Cases

• Analyzing the effects of bacterial inoculation on plant height and root length under salt stress.
• Studying changes in antioxidant enzyme activities (POD, SOD, CAT) and malondialdehyde (MDA) content in plant tissues.
• Investigating the relationship between bacterial traits (nitrogen fixation, IAA synthesis) and improvements in plant fresh/dry weight.
• Modeling osmotic regulation in plants based on reported changes in soluble sugar, protein, and proline content.

Strengths

• Reports specific, statistically significant percentage changes in key biochemical markers (e.g., POD activity increased by 92.75%).
• Describes a controlled pot experiment with a defined maize variety ('Ningdan 33') and a characterized bacterial strain (Enterobacter asburiae PW2).
• Details multiple measured plant growth-promoting traits of the bacterium, including nitrogen fixation and ACC deaminase activity.

Limitations

• Dataset is a single 224.4 KB PDF document; the underlying raw numerical or tabular data is not directly accessible.
• Column-level documentation is absent; field semantics and raw measurements must be extracted manually from the report.
• Row count is unknown, which may limit suitability assessment for quantitative modeling.
