Seedling Growth and Survival Data from Subtropical Forest Hyphal Exclusion Experiments

Experimental data from two hyphal exclusion experiments on ten common tree species in a subtropical forest. The dataset includes survival status, height, total biomass, component biomass, and percentage root colonization by mycorrhizas for seedlings transplanted with different mesh treatments. It was collected in the Heishiding Nature Reserve, Guangdong Province, China, and published by the Environmental Information Data Centre.

Use Cases

• Compare survival status and total biomass between ectomycorrhizal and arbuscular mycorrhizal tree species under different mesh treatments.
• Analyze the relationship between percentage root colonisation by mycorrhizas and seedling height or component biomass.
• Model the effect of mesh treatment and experimental block on growth metrics like height and biomass for ten identified botanical species.

Strengths

• Data covers ten distinct tree species, including five ectomycorrhizal and five arbuscular mycorrhizal types.
• Includes multiple measured growth and survival metrics per seedling: survival status, height, biomass, and root colonisation percentage.
• Experiment was conducted in a defined nature reserve (Heishiding Nature Reserve) with documented geographic coordinates.

Limitations

• Sample size (number of seedlings/rows) is not provided, limiting assessment of statistical power.
• Data is from a specific, single geographic location, which may limit generalizability to other forest ecosystems.
