Biomass and Hydraulic Resistance Scaling in Poplar Saplings

Han Zhao's dataset on figshare contains measurements from 141 poplar saplings across different ontogenetic stages. It quantifies aboveground biomass, biomass allocation, hydraulic resistance partitioning, leaf gas exchange, and water potential. The data supports empirical scaling rules for large-scale vegetation models.

Use Cases

• Model biomass allocation scaling rules based on the described allometric relationships.
• Analyze hydraulic resistance partitioning between stems and leaves based on the reported measurements.
• Study the relationship between tree size and leaf-level transpiration using the provided gas exchange and water potential data.
• Fit asymptotic versus power-law models to tree ontogeny traits as described in the study.

Strengths

• Includes data from 141 poplar saplings spanning a size gradient.
• Measures multiple traits including biomass, hydraulic resistance, leaf gas exchange, and water potential.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
