Understanding Variability of Leaf Trichome Density in Oregon White Oaks

Oregon white oaks (Quercus garryana) are an essential part of our local ecosystems due to the environment and food they provide to wildlife. Trichomes are hair-like appendages on the surface of leaves of plants and may function for herbivory defense and water retention.
Variation in trichomes has not been studied in Oregon white oak. To understand trichome variability in Oregon white oak, we collected leaves from 47 trees in Corvallis, OR in 2020 and measured trichome density in relation to habitat characteristics and tree anatomical traits. The average trichome density was 1542.728 trichomes/mm2. Trichomes were more dense on the abaxial (lower) side of the leaf compared to the adaxial (upper) side. Total trichome density was not impacted by habitat, tree sizes, or leaf mass to surface area ratio. The density of trichomes between individual trees was highly varied but was fairly consistent among leaves of the same tree. More research is needed to fully understand if trichomes are an adaptive trait for oaks and their specific functional significance.
