  • F-tests in partially balanced and unbalanced mixed linear models

    Creator:
    Utlaut, Theresa L.
    Abstract:
    This dissertation considers two approaches for testing hypotheses in unbalanced mixed linear models. The first approach is to construct a design with some type of structure or "partial" balance, so that some of the optimal properties of a completely balanced design hold. It is shown that for a particular type...

  • Developmental mutants of Phaseolus vulgaris L.

    Creator:
    Shii, Chou Tou
    Abstract:
    Hybrids with abnormal development were obtained when particular genotypes of Phaseolus vulgaris L. were crossed. The phenotypic aberrations of the F₁s included retarded growth, chlorosis of the trifoliate leaves and the formation of adventitious roots on the hypocotyls. The expression of the abnormalities was dependent on the temperature. At high...

  • Pectolytic enzyme production by Fusarium oxysporum f. sp. lycopersici

    Creator:
    Baldwin, Charles Harry
    Abstract:
    This investigation was undertaken to determine 1) the effects of various carbon sources in defined media on pectolytic enzyme production, 2) the effect of the incubation period on pectolytic enzyme activity, and 3) the development of improved methods for the purification and characterization of the polygalacturonases (PG) produced by Fusarium...

  • Endosperm morphogenesis in wheat (Triticum aestivum L.)

    Creator:
    Huber, Andrew Gail, 1944-
    Abstract:
    Wheat endosperm morphogenesis was studied by light microscopy during the entire growth period of anthesis to maturity. Four developmental stages have been described in this thesis: (1) double fertilization, (2) formation of the lower endosperm cells, (3) termination of nuclear divisions, and (4) initiation of protein bodies. The first manuscript...

  • Geneticist L.C. Dunn : politics, activism, and community

    Creator:
    Gormley, Melinda (Melinda Brooke)
    Abstract:
    L. C. Dunn (1893-1974) spent most of his scientific career conducting research in developmental genetics as a member of the Zoology Department at Columbia University in the City of New York. He had an accomplished scientific career researching mutations in mice, which earned him respect from other geneticists and scientists....

  • Genotype-environment interaction in winter wheat F₁ progeny

    Creator:
    Peterson, C. J.
    Abstract:
    Seven winter wheats were evaluated for plant height, the components of yield and yield in a diallel cross at Pendleton, Oregon and Lind, Washington. An additional parent was added to the diallel cross at Pullman, Washington. Two levels of nitrogen and five replications were utilized at each of the locations....

  • Characterization of two endopolygalacturonase isozymes produced by Fusarium oxysporum f. sp. lycopersici

    Creator:
    Strand, Larry L.
    Abstract:
    Polygalacturonase produced by Fusarium oxysporum f. sp. lycopersici was purified by chromatography on DEAE cellulose, CM cellulose, and hydroxylapatite. Removal of large amounts of carbohydrate by chromatography on hydroxylapatite did not affect heat stability of the enzyme. A large proportion of the remaining carbohydrate appeared to be covalently linked to...

  • Quantitative resistance to Puccinia striiformis f. sp. hordei in barley near-isogenic (BISON) lines

    Creator:
    Richardson, Kelley L.
    Abstract:
    Quantitative resistance (QR) to disease is usually more durable than qualitative resistance, but its genetic basis is not well understood. We used the barley/barley stripe rust pathosystem as a model for the characterization of the QR phenotype and associated genomic regions. As an intermediate step in the preparation of near-isogenic...
