  • The time-concentration interaction of Al toxicity in wheat root meristems

    Creator:
    Rhue, Roy Dean
    Abstract:
    The time-concentration interaction of Al toxicity in the root meristems of Brevor wheat was studied using the L.D. 50 as a criteria for Al damage. The L.D. 50 represented a precise, well defined degree of biological damage which was easily reproduced under conditions where factors like temperature, pH, nutrient concentration,...

  • The relationship of electrical impedance to vegetative maturity and dormancy in red-osier dogwood

    Creator:
    Parmelee, Kathleen Ann
    Abstract:
    Techniques to measure vegetative maturity and dormancy of deciduous nursery stock were investigated in red-osier dogwood. Previous methods which were based on: survival or tip dieback, change in level of ethylene production, xylem water potential, and alteration of square wave traces traces, provided no better indication of dormancy than did...

  • Measurement of nitrogenase activity of intact legume symbionts in situ using the acetylene reduction assay

    Creator:
    Fishbeck, Kathleen Ann
    Abstract:
    The process of biological nitrogen fixation involves the enzymic reduction of atmospheric nitrogen (N₂) to ammonia (NH₃). The enzyme which catalyzes this reduction, nitrogenase, does not exhibit a high degree of substrate specificity. It also catalyzes the reduction of acetylene (C₂2H₂) to ethylene (C₂H₄). The reduction of C₂H₂ to C₂H₄...

  • Transactional analysis applied to a community development issue

    Creator:
    Manolescu, Kathleen M.
    Abstract:
    Barth's theory of transactional analysis is applied to the community of Tiller, Oregon and its reaction to a development proposal. Community behavior patterns vis-a-vis the development proposal are examined from a processual point of view to determine how these patterns are generated. The community's history and contemporary situation are described....

  • The effect of soil acidity and lime placement on root growth and yield of winter wheat and alfalfa

    Creator:
    Kauffman, Marvin Dean
    Abstract:
    The application of lime to an acid Nekia soil significantly increased the yield of winter wheat and alfalfa in a field experiment. Crop yields maximized when the lime was partially mixed into the surface four inches of the soil. Thorough mixing of the lime into the surface six inches of...

  • Genotype x environment interactions in sheep

    Creator:
    Corum, Kathleen Steele
    Abstract:
    The 865 ewe production records taken from three lamb crops, were analyzed to study breed effects, heterosis, environmental effects and interactions between them, and breed and heterosis x environment interaction effects on ewe production traits. In each of two environments, approximately 144 ewes were mated in a three breed reciprocal...

  • Physical hydrography and nutrient nitrogen budget of Auke Bay, Alaska

    Creator:
    Kirk, Deborah Kathleen
    Abstract:
    Physical sources of nutrient nitrogen for the Auke Bay, Alaska estuarine ecosystem were investigated. These sources included vertical dispersion, advection, and fresh water sources. Hydrographic circulation patterns for the bay, and a nutrient budget for the surface mixed layer were developed. Measurements of temperature, salinity, currents, wind velocity, rainfall and...

  • Factors affecting a bioassay for Agrobacterium tumefaciens in natural soil

    Creator:
    Jaeger, Joy Rae
    Abstract:
    Tomato seedlings were used to assay the population of A. tumefaciens in artificially contaminated soil. Aqueous soil suspensions were applied directly to the wounded stem. The bioassay was used because not all pathologically important physiological strains of A. tumefaciens would grow on any of the selective media available. This method...

  • Photoinduction of kaurene synthetase, an enzyme of the gibberellin biosynthetic pathway, during de-etiolation of pea seedlings

    Creator:
    Gomez-Navarrete, Gladys
    Abstract:
    Previous investigations have shown that the enzymes catalyzing the biosynthesis of the gibberellin-type of hormones from mevalonic acid in plants are compartmentalized in plastids. Moreover, the activity of one of the key enzymes in the biosynthetic sequence, kaurene synthetase, exhibits markedly enhanced activity when a dark-grown pea seedling undergoes de-etiolation...

  • Aluminum toxicity in the primary meristem of wheat roots

    Creator:
    Henning, Stanley John
    Abstract:
    The progression and consequences of aluminum toxicity were studied microscopically in the root tips of four wheat varieties representing different classes of Al tolerance. The root tips studied were collected from seedlings grown in nutrient solution cultures containing either sublethal or lethal Al treatments which were unique for each variety....
