- Figure 1.
Diagram of study plot showing tree, trench, and Biobarrier placement. The 12 treated trees are opposite the 6 areas of trench containing the barrier fabric, and the remaining 12 trees provided controls. Spacing details are provided in the text.
- Figure 2.
Trench lined with Biobarrier showing roots (arrow) that grew to the barrier fabric but not into the trench. Roots are visible on the tree side of the barrier, and the target tree stands approximately 1.5 m (5 ft) away from the barrier.
- Figure 3.
Root from sweetgum treated with Biobarrier. Root section was stained with trypan blue and viewed with a brightfield light microscope. Note dark-staining hyphae and vesicles (arrows) of endomycorrhizal fungal symbiont (400X).
- Figure 4.
Pin oak roots from trees treated with Biobarrier. Roots were washed and examined under a stereo microscope. (a) Swollen short roots of ectomycorrhizae (above) compared with nonmycorrhizal roots (below) from same tree (15X). (b) Highly branched, swollen short roots typical of ecto-mycorrhizal infection taken from a tree treated with the barrier fabric (27.5X).
