Physiology of ripening in pears

Creator:: Wang, Chien Yi
Abstract:: Investigations were conducted to study in detail some biochemical and physiological aspects of ripening in pears. Anjou pears picked at different degrees of maturity were treated with Ethrel (2-chloroethane phosphonic acid), 4000 ppm, and ethylene, 500 ppm, for different lengths of time. Respiration rate was measured twice daily and changes...

The biology and control of reed canarygrass (Phalaris arundinacea L.) on irrigation ditchbanks

Creator:: Comes, R. D. (Richard Durward), 1931-
Abstract:: Reed canarygrass (Phalaris arundinacea L.) is a desirable pasture grass on wet areas in the Northern United States and Southern Canada, but it is a serious and troublesome ditchbank weed in the Pacific Northwest and Rocky Mountain States. The purpose of this study was to learn more about the development,...

Student performance in lower division collegiate general biology programs in selected community colleges and four-year institutions in Oregon

Creator:: Tolman, Richard Robins
Abstract:: It was the intent of this investigation to compare the performance of community college students to four-year institutional students, both of whom were enrolled in a college general biology program (GS 101, 102, 103) during the 1967-68 academic year. During the week of May 27, 1968 measurements were taken of...

Patterns in coastal marsh vegetation of the Juneau area, Alaska

Creator:: Stone, Catherine S.
Abstract:: A vegetation study was made of four coastal marshes near Juneau, Alaska. Results confirmed earlier studies' findings in southeast Alaska that communities or assemblages of species can be identified but from marsh to marsh these assemblages appear to have no consistent relationship to each other or to environmental "factors" such...

An ecological study of Diatomovora amoena, an interstitial acoel flatworm, in an estuarine mudflat on the central coast of Oregon

Creator:: Thum, Alan Bradley
Abstract:: The distribution and abundance of the interstitial acoel turbellarian, Diatomovora amoena Kozloff, 1965 was studied in an estuarine intertidal sand flat in Yaquina Bay, Oregon, from May 1970 through May 1971. Monthly measurements of biological (organics, sulfides, chlorophyll, and carotenoids), pore water (salinity, pH,oxygen, and temperature), and sediment (fine sediment...

Selective inhibition of ion absorption by uranyl

Creator:: Mason, Benjamin J.
Abstract:: The research presented in this thesis evaluated the effects of uranyl (UO₂⁺⁺) upon the absorption of Li, Na, K, Rb, and Cl. Due to the biological importance of Na and K, these two ions were studied in the greatest detail. The results of this research showed that, at UO₂⁺⁺ concentrations...

The effect of selected potassium salts on the availability of soil manganese

Creator:: Westermann, D. T. (Dale Thomas), 1941-
Abstract:: Incubation experiments with an acid poorly drained soil have shown that the application of neutral soluble salts influenced the level of extractable Mn. The application of a salt which lowered the soil pH either increased the extractable Mn or retarded the oxidation and/or fixation of extractable Mn. This effect was...
