What you'll learn

✓ Prepare intact tree phloem tissue for microscopic observation
✓ Construct a phloem sandwich apparatus for organism study
✓ Introduce and observe arthropods and microbes in phloem

Protocol

We provide a technique to preserve intact tree phloem and prepare it for observation. We create an apparatus called a phloem sandwich that allows for the introduction and observation of arthropods, microbes, and other organisms that inhabit phloem tissues.

Difficulty

intermediate

Total time

~2–3 hours per sample (including tree selection, phloem extraction, and apparatus assembly)

Steps

Select appropriate tree specimen for phloem extraction

Identify and select a suitable tree based on species and tissue quality requirements. Assess phloem accessibility and health status.

▶ 00:29

Remove phloem tissue from selected tree

Carefully extract intact phloem tissue from the tree using appropriate dissection techniques to preserve tissue structure and viability.

▶ 01:58

Assemble phloem sandwich observation apparatus

Construct the phloem sandwich device by layering and securing the extracted phloem tissue between supporting materials to maintain integrity during observation.

▶ 03:05

Observe representative results and validate technique

Examine prepared phloem sandwich under microscopy to visualize arthropod and microbial communities within the tissue.
