DOI: 10.3791/52337-v
What you'll learn
  • ✓ Sample wooden specimens using appropriate dendroecological techniques
  • ✓ Prepare macro- and microscopic slides for wood anatomy analysis
  • ✓ Generate high-resolution digital images of tree-ring anatomical features
  • ✓ Interpret growth structures and dendroecological datasets from wood samples
Protocol

Here we present a protocol outlining how to sample wooden specimens for the overall assessment of their growth structures. Macro- and microscopic preparation and visualization techniques necessary to generate well-replicated and highly resolved wood anatomical and dendroecological dataset, are described are described.

Difficulty
intermediate
Total time
~4–8 hours per specimen (sampling to imaging; varies by wood density and desired resolution)

Steps

1
Collect wood specimens using dendroecological sampling methods

Select and extract wooden samples from trees or stored specimens using standardized techniques to ensure representative growth-structure data.

▶ 01:33
2
Prepare samples for macro and microscopic examination

Cut, sand, and condition wood samples to expose annual rings and anatomical features suitable for both visual inspection and microscopic analysis.

▶ 02:49
3
Prepare microslides of wood tissue sections

Mount thin sections of wood on glass slides following standard histological protocols to enable microscopic observation of cellular anatomy.

▶ 04:30
4
Capture high-resolution digital images of anatomical structures

Image prepared specimens and slides using macro and microscopic photography to create documented datasets of tree-ring features and wood anatomy.

▶ 05:53
5
Analyze and interpret tree-ring growth patterns

Examine representative results by measuring ring widths, identifying anatomical markers, and extracting dendroecological information from prepared and imaged samples.
