Alternative Water Sources In Western Conifers Via Foliar Uptake And Hydraulic Redistribution, Ariel Sol Weisgrau

Cal Poly Humboldt theses and projects

Water is often the most limiting resource in a plant’s environment. Plants that can maximize their ability to acquire water improve their chances of success. Outside of the traditional soil-plant-atmosphere continuum, plants can alternatively acquire water via foliar uptake of water and hydraulic redistribution (HR) of deep water. This study used greenhouse-based experiments to investigate water use and physiology in four conifer species native to the western U.S.: Picea sitchensis (Bong.) Carriére (PISI), Pseudotsuga menziesii (Mirb.) Franco (PSME), Sequoia sempervirens (D. Don) Endl. (SESE), and Thuja plicata Donn ex. D. Don (THPL). First, this work investigated the capacity for foliar …
