  • Effects of flooding on peach, apple, quince and several pear species

    Creator:
    Andersen, Peter C.
    Abstract:
    A series of experiments was designed to investigate differential flood-tolerance and the phenomenon of flood-induced stomatal closure of several fruit tree species. The first two experiments were conducted with potted plants submerged outdoors 5-10 cm above the soil line. Plant morphology, growth, leaf conductance (cL), and soil oxygen diffusion rate...

  • Physiology of flowering in Coffea arabica L. : role of growth regulators and water relations

    Creator:
    Schuch, Ursula K.
    Abstract:
    Coffee trees growing in the Kona district of Hawaii were treated with different concentrations of either BA, GA3, or Promalin, and pruned at the time of flowering. No significant differences in the flowering and fruit ripening pattern were found. High concentrations (100 mg/1) of growth regulators decreased fruit fresh weight....

  • Effects of irrigation and nitrogen on cauliflower development, yield and quality

    Creator:
    Bratsch, Anthony D.
    Abstract:
    Field experiments were conducted with cauliflower (Brassica oleracea var. botrytis cv. Snowball Y ) to determine crop development, yield, quality and maturity response to various seasonal water levels, and to specific water stress timing in relation to curd initiation. The effects of nitrogen rate, timing, and source and the application...

  • Soil organic matter management and root health

    Creator:
    Darby, Heather
    Abstract:
    Annual applications of fresh or composted dairy manure were assessed for their effects on root rots of sweet corn and snap bean and damping-off of cucumber in a field soil. Soil biological and physical properties were measured as possible indicators of root rot suppressive potential. Regardless of amendment type or...

  • A closed root environment for plant production

    Creator:
    Blackburn, Bryan (Bryan Keith), 1955-
    Abstract:
    Thesis research focused on: 1) Water and fertilizer gradients within the plant root zone, and effects of chemical and physical gradients on Trichoderma harzianum populations. 2) Regulation of root growth physically with permeable fabric containers and chemically with copper compounds. 3) Effects of copper coatings for fabric containers on Glomus...

  • Serial manure amendments : effects on soil properties and root rot of sweet corn

    Creator:
    Cox, Bonnie S. Hoffman
    Abstract:
    The effect of serial (multiple-year) organic matter (OM) amendment on soil properties has been described in some cropping systems, although less is known about the effect of serially amended field soils on soil-borne plant diseases. The objectives of this study were to describe the effects of the third and fourth...
