Ecotypic adaptation of Setaria lutescens (Weigel) F. T. Hubbard to alfalfa culture in California

Creator:: Schoner, Carl Arnold
Abstract:: Setaria lutescens (yellow foxtail) plants, grown from five seed sources were compared in California. Seed sources were: Connecticut, Iowa, Massachusetts, Pennsylvania and California. Morphological and physiological differences between biotypes include: plant size, growth habit, time required to mature and reproductive capa city. Most significant is the prostrate habit of the...

Identification and Occurrence of Sweet Cherry (Prunus avium) Virus and Virus-Like Diseases in Various Regions and Orchards of Oregon

Creator:: Reinhold, Lauri A.
Abstract:: There are over 35 known virus and virus-like diseases of sweet cherry (Prunus avium), some with potential to cause severe economic impact by reducing vegetative growth, vigor, and/or quality of fruit. Oregon is the second-ranked state for sweet cherry production in the United States with 13,000 acres and $70.8 million...

Description of the plant communities and succession of the Oregon coast grasslands

Creator:: Ripley, James Douglas
Abstract:: In an effort to describe the plant communities and succession of the Oregon coastal grasslands, vegetation and environmental data were collected from 75 stands at 24 separate locations ranging from Cape Falcon in Tillamook County to Cape Ferrelo in Curry County. The vegetation data consisted of cover and frequency values...

Qualitative changes in cytoplasmic proteins in plants treated with plant growth regulating chemicals

Creator:: Norris, L. A.
Abstract:: This thesis concerns the alteration of the course of selective protein synthesis and morphogenesis in plants treated with growth regulating chemicals. Treatment of 48-hour-old "Alaska" pea seedlings (Pisum sativum L.) with 2, 4-D, IAA, NAA or picloram caused inhibition of epicotyl and primary root elongation and proliferation of massed lateral...

Pathological and ecological aspects of decline and mortality of Chamaecyparis nootkatensis in southeast Alaska

Creator:: Hennon, Paul Edward
Abstract:: Alaska-cedar (Chamaecvparis nootkatensIs (D. Don) Spach) is a valuable tree that is suffering from a serious decline and mortality of unknown cause throughout southeast Alaska. Epidemiological and pathological studies were initiated to determine if a pathogen is the primary cause of this problem. By examining old aerial photographs and by...

The Primary Disease Gradient of Wheat Stripe Rust (Puccinia striiformis f. sp. tritici) Across Spatial Scales

Creator:: Farber, Daniel
Abstract:: Wheat stripe rust (WSR), also called yellow rust of wheat (Tricitum spp.), causal agent Puccinia striiformis f.sp. tritici (Pst), is a foliar disease of major economic importance on wheat, especially grown in temperate locations. WSR causes major losses of wheat yield, estimated at nearly $ 1 billion per year, and...

Reevaluation of systematic relationships in Triticum L. and Aegilops L. based on comparative morphological and anatomical investigations of dispersal mechanisms

Creator:: Morrison, Laura A.
Abstract:: Comparative morphological and anatomical studies of the dispersal mechanisms characterizing the wheat complex (Triticum L. and Aegilops L.) have documented patterns of adaptive radiation which may have significance for evolutionary relationships. These patterns, which form an array of diverse types of diaspores among the diploid taxa, appear conceptually to have...

Foliar respiration in an old-growth coniferous forest

Creator:: Cooper, Clifton E.
Abstract:: Foliar respiration forms a large component of the carbon balance of any coniferous forest. We examine seasonal, interannual, spatial and interspecific variation of foliar maintenance respiration in a forest in Washington, USA, with measurements made quarterly for >4 years on 400-year old trees of Pseudotsuga menziesii, Tsuga heterophylla and Thuja...

Effects of host resistance on Mycosphaerella graminicola populations

Creator:: Cowger, Christina
Abstract:: Mycosphaerella graminicola (anamorph Septoria tritici) causes Septoria tritici blotch, a globally important disease of winter wheat. Resistance and pathogenicity generally vary quantitatively. The pathogen reproduces both sexually and asexually, and the pathogen population is highly genetically variable. Several unresolved questions about the epidemiology of this pathosystem are addressed by this...
