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....

Distortions to travel cost derived demand curves : water quality and durable goods

Creator:: Garifo, Susan E.
Abstract:: The travel cost method of deriving demand and value of recreation does not include fixed costs of recreational durable goods purchases or allow for supply restrictions on the number of suitable sites available. The omission of these two real-world situations results in derivation of demand curves which are more inelastic...

Disposal of sandy pipeline dredge spoils by end dumping

Creator:: Pyles, Marvin Russell
Abstract:: Channel maintenance operations in the rivers and harbors of the United States annually require the disposal of over 320 million cubic meters of dredge spoils. As the availability of suitable land sites diminishes, open water disposal presents an attractive yet controversial alternative method. For open water disposal to be acceptable,...

Vernalization requirement studies with Pacific Northwest wheats

Creator:: Baloch, Dost M.
Abstract:: Vernalization plays a fundamental role in the adaptation of winter cereals to their growing environment by controlling their growth habit, thereby allowing them to escape cold injury. Because of the climatic conditions of the region, dry summers and wet winters, growers sometimes cannot plant all of their winter wheat in...

Evaluation and use of a soil mineralizable nitrogen test to determine the fertilizer nitrogen needs of winter wheat grown in western Oregon

Creator:: Baloch, Dost M.
Abstract:: The assessment of optimum nitrogen (N) fertilizer need for winter wheat (Triticum aestivum L.) is important for economic and environmental sustainability. A comprehensive understanding of fertilizer N requirement depends on estimation of the quantity of N needed by the crop versus that supplied by soil. The objectives of this study...

Changes in the lipid composition of rainbow trout (Salmo gairdnerii) fed cyclopropenoid fatty acids

Creator:: Roehm, Jeffrey Noyes
Abstract:: Rainbow trout were fed semi-purified diets containing cyclopropenoid fatty acids, and the biological effects of these acids were investigated. These fatty acids occur naturally in cottonseed oil and have been implicated in a large number of physiological disorders. Included in this study was an investigation of the pattern of deposition...

Dietary protein and aflatoxin B₁ metabolism in rainbow trout (Salmo gairdneri)

Creator:: Stott, William T.
Abstract:: Dietary protein intake has been observed to influence the induction of cancer in animals exposed to carcinogens, presumably by affecting the activities of enzyme systems which metabolize them. One such carcinogen is aflatoxin B₁ (AFB₁) a mold metabolite and frequent contaminant of foodstuffs. Variations in the levels of dietary proteins...
