The effect of variation of some physical and chemical factors on the rate of growth of Botyrococcus braunii (Chlorophyta, Chlorococcales)

Creator:: Julian, Larry L.
Abstract:: The culture of the green alga Botryococcus braunii Kutz. obtained for use in this study was contaminated with bacteria and fungi. Algal colonies from this culture sonicated, rinsed and treated with penicillin (500 μg/ml), gentamicin sulfate (50 μg/ml) and amphotericin B (5 μg/ml) were found to be axenic when incubated...

Primary productivity and community structure of an estuarine impoundment

Creator:: Lyford, John Higgins
Abstract:: An impounded estuary was employed to study primary productivity, community respiration, and community structure as they related to seasonal and temporal succession, salinity, and water temperature. Plankton metabolism was studied by means of the light-and dark-bottle technique. Benthic community metabolism was determined by using the "diurnal oxygen curve" method. Four...

Growth of Aphanizomenon flos-aquae in defined media

Creator:: O'Flaherty, Larrance Michael Arthur, 1941-
Abstract:: A strain of Aphanizomenon flos-aquae Born. et Flah. has been introduced into culture and maintained since August of 1964 in completely defined media. It exhibits the planktonic, colonial flake form found in nature, and both heterocysts and akinetes are present. The color and size of the flake and general appearance...

Developing techniques for evaluating the susceptibility of root-disease resistant Port-Orford-Cedar to foliar and stem canker diseases.

Creator:: Martin, Danielle K. H.
Abstract:: Since around 1923 Port-Orford-cedar (Chamaecyparis lawsoniana (A. Murray) Parl.) has been affected by Phytophthora root disease caused by the virulent introduced pathogen Phytophthora lateralis. A systematic resistance testing and breeding program located at the USDA Forest Service Dorena Genetic Resource Center in Cottage Grove, Oregon was initiated in 1997 with...

Evaluation of the colonization and biofilm production by Burkholderia pyroccinia FP62 on geranium leaves

Creator:: Wallace, Patricia K.
Abstract:: The leaf surface is a stark environment for bacterial colonists with limited availability of nutrients, water and protected niches. Despite these limitations, a plethora of bacteria appear to have adapted ways to survive and flourish on leaf surfaces. One mechanism of survival is the formation of biofilms. Biofilms are a...

Characterization of strains of Scenedesmus resistant to the herbicide DCMU, (3-(3,4-dichlorophenyl)-1,1-dimethylurea)

Creator:: Smith, Muriel K.
Abstract:: Three DCMU resistant mutants of the green alga Scenedesmus obliquus D₃ are characterized. The mutants exhibit a ten fold greater resistance to DCMU than the wild type strain; this is comparable to the level of DCMU resistance detected in other DCMU resistant algae. In whole cell reactions, as well as...

Physiologic specialization of stripe rust (Puccinia striiformis West.) in the Pacific Northwest

Creator:: Beaver, Richard Gary, 1939-
Abstract:: The physiologic specialization of nine isolates of stripe rust (Puccinia striiformis West.) collected in the Pacific Northwest was determined. The separation of races was based on the differential susceptibility of the following wheat varieties: Cappelle Desprez, Chinese 166, Dippes Triumph, Druchamp, Etoile de Choisy, Flamingo, Gaines, Golden, Ibis, Leda, Michigan...

Relationship of Pratylenchus penetrans (Cobb, 1917) population density and yield of peppermint, Mentha piperita L.

Creator:: Pinkerton, John Nelson
Abstract:: A root-lesion nematode, Pratvlenchus penetrans, was determined to be a major component of peppermint stand decline in Western Oregon. Regression analysis showed that P. penetrans root densities in August were negatively correlated (P=0.01) with yield, while soil densities in August and root and soil densities in April were poorly correlated...
