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....

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...

Determination of the quality of radiation-pasteurized halibut (Hippoglossus stenolepis) during storage

Creator:: Serrano, Lolita Bate
Abstract:: The quality of radiation-pasteurized halibut stored at 34°F was evaluated subjectively and objectively over a period of 18 weeks. Results of flavor evaluation and chemical analyses showed that the storage life of halibut irradiated at 0.50, 0.75 and 1.00 megarad was extended more than threefold. Although irradiated samples were consistently...
