Architecture, size, and reproduction in plants : a pollination study of Mertensia ciliata (James) G. Don

Creator:: Geber, Monica
Abstract:: I experimentally test the hypothesis that the potential for selfing increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible, profusely-flowering perennial. This follows from the premises that 1) pollen dispersal by pollinators between flowers is limited, and 2) individual pollinators, in this study bumblebees, will visit more flowers per...

An economic evaluation of yield grade standards for Canadian carcass beef

Creator:: Dawson, Oliver Glenn
Abstract:: The basic objective of this thesis was to estimate the economic effects of yield grade standards for carcass beef on the various market sectors of the Canadian beef industry. The adoption of the standards was expected to enhance consumer demand, improve efficiency within the processing and marketing services sectors, and...

Subterranean clover yield and nutrient content as influenced by soil molybdenum status

Creator:: Bhella, Harbans Singh
Abstract:: During the Spring of 1969, 47 surface soil samples (0 to 15 cm) as well as foliage samples of subterranean clover were collected from 32 selected western Oregon pastures, in an effort to determine their molybdenum status and to evaluate the use of anion exchange resin method as a means...

Molybdenum status of selected Oregon soils and subterranean clover response to molybdate

Creator:: Ross, Erric Virgil
Abstract:: Studies were undertaken on the Steiwer, Hazelair, Hedden, Dixonville, Knappa, Haines, Ladd, Wingville and Powder soil series plus three additional unnamed soils from western Oregon, in an effort to determine their molybdenum status and to evaluate the use of the anion exchange resin method as a means of assaying available...

Response of field corn to irrigation, plant population, and nitrogen on soils of the Willamette catena

Creator:: Andersen, Jimmie Lee
Abstract:: The purpose of this study was to make a preliminary investigation of the productivity of some of the soils within the Willamette catena under different systems of soil management. The study was carried out at four experimental sites near Corvallis, Oregon, during the 1962 growing season. The soil at each...

Response of Cuscuta campestris and Cuscuta indecora to glyphosate applied after attachment to alfalfa (Medicago sativa)

Creator:: Fessehaie, Rezene
Abstract:: The response to glyphosate [N-(phosphonomethyl) glycine] of two dodder species Cuscuta campestris Yuncker (field dodder) and Cuscuta indecora Chiosy (largeseed dodder) parasitizing alfalfa (Medicago sativa L.) was compared. In the absence of glyphosate, alfalfa was killed or severely injured by parasitism from uncontrolled dodder. Results of field experiments in which...

William Ernest Castle, American geneticist : a case-study in the impact of the Mendelian research program

Creator:: Taylor, H. Terry
Abstract:: In their modern context questions of heredity have come to be closely aligned with theories of evolution because all such theories require the presence of heritable variation. Thus the need for an understanding of a source of variation and a mechanism for its inheritance became very apparent with the general...
