  • Variation and heritability of vegetative, reproductive and fruit chemistrytraits in black raspberry (Rubus occidentalis L.)

    Creator:
    Dossett, Michael
    Abstract:
    In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants. Present cultivars are ill adapted...

  • Genome sizing and fire blight resistance screening in Cotoneaster

    Creator:
    Rothleutner, Joseph J.
    Abstract:
    Cotoneaster is an ornamental shrub valued for showy flowers, berries and architecture as well as the ability tolerate adverse conditions under which other taxa fail. Cotoneaster is a highly diverse genus of over 400 species, of which few are available in the US nursery trade. Some species commercially available have...

  • Herbicidal effect of glyphosate as influenced by spray drop size

    Creator:
    Chyau, Anna Tai-yung
    Abstract:
    An aqueous solution of technical glyphosate [N-(phosphonomethyl) glycine] was applied in homogeneous sprays of 120, 180 and 300 μm droplets to seedlings of a bush type green bean (Phaseolus vulgaris L. 'OSU 1604') at a carrier rate of 20 1/ha. At each droplet size all combinations of 3 dosage levels...

  • Bees of the Pacific Northwest : key to genera (Hymenoptera : Anthophila)

    Creator:
    Best, Lincoln R., Dunlap, Joshua B., Jackson, August S., and Rivers, James W.
    Abstract:
    This key to the bee genera of the Pacific Northwest provides dichotomous couplets which aid the user in identifying 60 genera of bees which occur or may occur in the region. The key architecture is based strongly on the key to the genera of North and Central America published in...

  • Breeding tomato for increased fruit phenolics

    Creator:
    Boches, Peter S.
    Abstract:
    The purpose of this research was to develop tools and germplasm for the production of tomatoes (Solanum lycopersicum L.) with high fruit phenolics without the use of genetic engineering. A candidate gene analysis was undertaken to identify genes regulating anthocyanin biosynthesis in tomato fruit (Aft, Abg, atv, and Purple Smudge)....

  • Evaluation of genetic diversity in wild populations of black raspberry (Rubus occidentalis L.)

    Creator:
    Dossett, Michael
    Abstract:
    In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred, in part, by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants.

  • Cryopreservation of in vitro-grown apical meristems

    Creator:
    Chang, Yongjian
    Abstract:
    Alternating temperature (22°C / -1°C) pretreatments were effective for increasing cold hardiness and recovery of cryopreserved meristems. Combining low temperature pretreatment with abscisic acid (ABA) or sucrose treatments reduced the time required for optimal cold hardiness of meristems. Desiccation tolerance was directly correlated with increased cold hardiness and recovery of...

  • Phenology, Host-Plant Resistance, and Biological Control of Stephanitis pyrioides in Oregon

    Creator:
    Flores, Salvador M.
    Abstract:
    The azalea lace bug (Stephanitis pyrioides Scott) is a recently detected invasive pest to the Pacific Northwest and has become a major concern in Oregon. It feeds on azaleas as well as rhododendrons causing stippling on the top side of leaves. The damage is aesthetically displeasing and affects plant vigor...

  • Boron nutrition and fruit set of 'Italian' prune

    Creator:
    Hanson, Eric J.
    Abstract:
    Foliar B sprays have increased fruit set in 'Italian' prune (Prunus domestica L.) by 2 fold in some trials and had no effect in others. This work was conducted to identify reasons for this inconsistent response. Since B levels in flowers are associated with the amount of fruit set, factors...
