Amino acids in tissues from healthy and crown gall infected Kalanchoe pinnata

Creator:: Harris, Raymond Gene
Abstract:: Crown gall infected and healthy Kalanchoe pinnata (Lam.) Persoon plants were analyzed for soluble amino acids. Specifically the amino acids in young leaf, mature leaf, stem, root, and gall tissues were quantitatively measured. The plants were inoculated with the bacterium, Agrobacterium tumefaciens (Smith and Townsend) Conn., on one side of...

Interactions between paired cultures as a basis for differentiating compatibility genotypes of Fomes cajanderi Karst. from glaze-damaged Douglas-fir

Creator:: Adams, David Howard
Abstract:: A study was undertaken to determine the reliability of the formation of a line of demarcation between paired cultures of Fomes cajanderi Karst. as an indicator of dissimilar compatibility genotypes. The results were applied to an assay of the number and location of compatibility genotypes in each of four glaze-damaged,...

Yield responses of invasive grasses to carbon doses

Creator:: Brunson, Jessi L.
Abstract:: The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L. (cheatgrass) and Taeniatherum caput-medusae (L.) Nevski (medusahead). Restoration of invasive-dominated areas is difficult, but can be enhanced by adding a carbon...

Conservation biology of Perideridia erythrorhiza (Apiaceae) : experimental reintroduction and life history

Creator:: Roberts, Kimberly A.
Abstract:: An experimental reintroduction was performed to determine the best method to create new populations of the tuberous species Perideridia erythrorhiza, a rare vascular plant endemic to southern Oregon. Only a handful of sites are currently present, and many of these are subject to other land uses such as urban development...

Science Takes Flight: Detection of Black Leg on Turnip Gray Mold on Hemp

Creator:: Bates, Taylor A.
Abstract:: Disease detection through traditional techniques such as scouting fields on foot, molecular assays, or morphological identification of plant pathogens is time consuming and costly. Disease diagnosis in the field can be extremely subjective, and largely depends on the experience and knowledge of pathogen identification and disease quantification. This thesis provides...

Identification and distribution of the mating-type locus and development of cleistothecia of Podosphaera macularis

Creator:: Wolfenbarger, Sierra N.
Abstract:: Podosphaera macularis, causal agent of hop powdery mildew, is known to produce cleistothecia (syn. chasmothecia) in eastern North America and Europe, but ascocarps are not reported from the Pacific Northwestern region of North America. Reasons for the apparent absence of cleistothecia in the Pacific Northwest are unknown. We established that...

The Influence of Nitrogen Fertility on Hop Quality, Pest Management, and the Stability of Biological Control

Creator:: Iskra, Anne E.
Abstract:: A multi-year field study was conducted in Oregon and Washington to evaluate the influence of nitrogen fertilization rate and timing on cone quality, nitrate accumulation in cones, severity of powdery mildew (caused by Podosphaera macularis), arthropod pests, and the stability of conservation biological control of the twospotted spider mite (Tetranychus...
