Frost hardiness of buds, flowers and fruit of pear (Pyrus communis L.)

Creator:: Strang, John George
Abstract:: Spring frost damage to pears in the Pacific Northwest frequently results in substantial crop losses. This research was undertaken to investigate the effects of frost on pear buds, flowers, and fruit through controlled freezing tests and field studies in order to better understand the frost phenomenon and refine frost protection...

Evaluation of Vitis rootstocks for tolerance to low soil pH

Creator:: Taylor, Patrick Andrew
Abstract:: The purpose of this study was to determine the relative tolerance of grafted Vitis rootstocks to low soil pH. In this capacity, the data may be pooled with results from previous investigations to increase the overall aptitude profile of Vitis rootstocks. A potential application of this information is that the...

Facilitating plant-parasitic nematode management decisions for Washington Vitis vinifera growers : determining the spatial distribution of plant-parasitic nematodes and the host status of Vitis spp. to Meloidogyne hapla

Creator:: Howland, Amanda D.
Abstract:: A major constraint to the production of self-rooted wine grapes (Vitis vinifera) in eastern Washington is plant-parasitic nematodes. Plant-parasitic nematodes can impact grape productivity by limiting water and nutrient uptake, educing physiological changes, and extracting plant nutrients from roots, thereby reducing root biomass, plant vigor, and yield. The most commonly...

Water partitioning and respiration activity of dormant grape buds

Creator:: Gardea, Alfonso A.
Abstract:: Dormancy of 'Pinot Noir' grapevines was characterized. Primary buds required ca 300 cumulative chilling hours (CCH) to initiate the transition from endodormancy to ecodormancy, which occurred in mid November. Additional chilling, up to 1000 CCH, improved budbreak. Changes in bud water content were estimated by gravimetric and spectroscopic methods. Total,...

Relationships between endogenous phenolic compounds of rhododendron tissues and organs and cold hardiness development

Creator:: Chalker-Scott, Linda
Abstract:: The leaching of water soluble phenolic compounds from cold stressed Rhododendron leaves was found to be a reliable indicator of tissue damage. In sublethally stressed leaf tissues, more and novel phenolic compounds appeared and were hypothesized to be precursors of cell wall components such as lignin and suberin. Subsequent radiolabeling...

Using Vineyard Floor Management to Manipulate Vine Vigor: Impacts on 'Pinot noir' Yield Productivity and Fruit Composition

Creator:: Reeve, Alison L.
Abstract:: Winegrapes are an important crop for Oregon agriculture, ranking amongst the top ten agricultural commodities based on farmgate value. The most widely planted winegrape cultivar in the state is ‘Pinot noir’ (Vitis vinifera L.), and the majority of acreage is produced in the Willamette Valley. Production of quality ‘Pinot noir’...

Embryo development in relation to interspecific hybridization of Phaseolus

Creator:: Rabakoarihanta, Aimee
Abstract:: Interspecific hybridizations between P. vulgaris and P. acutifolius and between P. vulgaris and P. lunatus were investigated. Prefertilization events were similar in inter- and intra-specific crosses. Fertilization was completed in all crosses and the time of fertilization was dependent on the maternal parent, reflecting differences in the time of maturation...

Influencing flower initiation and flower cluster set in the 'Barcelona' filbert with growth regulators

Creator:: Romines, Marsha Lynn
Abstract:: The alternate bearing cycle in the 'Barcelona' cultivar poses a major problem to the filbert industry. This study was conducted to alleviate this problem in one of two ways: by (1) increased floral initiation in the "on" year, and (2) increased cluster set in the "off" year. Growth regulators were...
