Observing Orobanche Uniflora Parasitism Of Four Sedum Species In Relation To Soil Composition, Devin J. Forest-Hines, Sophie Wille, Noah Flick, Maxxie Barr
Student Research Symposium
Sedums are commonly selected for green roof applications due to their horizontal growth, heat and drought tolerance, water-storage capacity, and heat absorption. A potential threat to sedum health is the presence of parasitic Orobanche. Orobanche are a genus of parasitic plants that extract nutrients, water and carbohydrates from its host via root attachments. This study seeks to investigate Orobanche parasitism on the four most abundant sedum species on a Portland State University green roof in relation to soil composition. Four sedum species were propagated in clear plastic compact-disc (CD) cases containing either mineral substrate, Miracle Gro, or a seedling mix, …
