G., and Yoder, J. A.
Abstract:: Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems and contributes roughly half of the Earth's net primary production. For 13 years, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission provided the first consistent, synoptic observations of global ocean ecosystems. Changes in the surface chlorophyll concentration, the primary...

A revision of Juncus subgenus genuini (Juncaceae) in the Pacific states

Creator:: Lint, Harold LeRoy
Abstract:: A study was made of the subgenus Genuini of the genus Juncus in the Pacific States, California, Oregon and Washington. Extensive morphological comparisons, geographical distributions, habitat differences and observations of apparent presence or absence of natural hybrids provided the major data sources. Cytological studies were made, but were inconclusive. Eleven...

Cytokinin oxidase activity from Phaseolus vulgaris L. cv. Great Northern callus tissues

Creator:: Chatfield, J. Mark
Abstract:: Cytokinin oxidase activity in callus tissues of Phaseolus vulgaris L. cv. Great Northern has been examined using an assay based on the oxidation of radioactively labeled N⁶ -(Δ² -isopentenyl) adenine (i⁶Ade) to adenine (Ade). Conditions for the quantitative extraction and assay of the enzyme have been established. The substrate specificity...

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...

A chemosystematic study of the phylogenetic position of Arabidopsis thaliana (L.) heynh. (Brassicaceae) employing numerical methods

Creator:: Kaplan, Hesh J.
Abstract:: The Brassicaceae, Mustard Family, is a well marked natural family, whose tetramerous flowers, tetradynamous stamens, and distinctive bi- carpellary fruits, clearly distinguish it from related families. It is a large family of some 3, 000 recognized species and over 300 genera. Although numerous attempts have been made over the past...

Identification of Endogenous and Exogenous Pararetroviruses in Red Raspberry (Rubus idaeus L.) and Blueberry (Vaccinium corymbosum L.)

Creator:: Diaz Lara, Alfredo
Abstract:: The Pacific Northwest (Oregon and Washington in the United States and British Columbia in Canada) is one of the major producers of red raspberry (Rubus idaeus L.) and blueberry (Vaccinium corymbosum L.) in the world. The expansion of growing area with these crops has resulted in the emergence of new...

Ozone flux in Helianthus annuus (L.)

Creator:: Smith, Elaine D.
Abstract:: Sunflower (Helianthus annuus L., cv. NK894) seedlings, grown hydroponically, were exposed to ozone concentrations of 0.0, 0.1, 0.2, and 0.3 ppm at 60% RH, or 0.0 and 0.3 ppm at 30% and 90% RH, for 6 h/d, for four consecutive days, at ages 15 to 18 days from seeding. Plant...

Population dynamics, extraction, and response to nematicide of three plant parasitic nematodes on peppermint (mentha piperita L.)

Creator:: Merrifield, Kathryn J.
Abstract:: The efficiencies of wet sieving/sucrose centrifugation (WS/SC) recovery of Pratylenchus penetrans (59 %), Paratylenchus sp., (80 %), and Criconemella xenoplax (66 %) were established. Baermann funnels (BF) recovered significantly more P. penetrans (p = 0.01) and significantly less (p = 0.01) C. xenoplax than did WS/SC. While densities of P....
