Cereal residue effects on weeds and cucumbers

Creator:: Peachey, Ronald Edward
Abstract:: Cereal residues suppress the development of small seeded, summer annual weeds. The focus of this study was to determine whether cereal residues can be used to suppress weeds in cucumber production systems in the Pacific Northwest. In the first of three experiments, cereal residues of fall-planted, spring-killed cover crops suppressed...

Physiological effects of non-nutritive sugars on the survivorship and fecundity of Drosophila suzukii (Diptera: Drosophilidae)

Creator:: Tang, Siew Bee
Abstract:: Spotted wing drosophila (SWD), Drosophila suzukii, is an economically damaging pest on small fruits. The estimated economic impact is hundreds of millions of dollars annually in the U.S. alone, and increasing every year. Current control of SWD relies heavily on chemical insecticides which have many negative impacts on environmental and...

Identification of cytokinin reductase in Phaseolus embryos

Creator:: Martin, Ruth C.
Abstract:: A critical balance of hormones is necessary for normal plant development. Therefore, precise mechanisms must exist to maintain proper levels of cytokinins, a group of hormones regulating cell division and differentiation. Structural modifications of the naturally occurring cytokinin, zeatin; including the oxidation, O-glycosylation and reduction of the N⁶-side chain; may...

Storage quality of broccoli florets and evaluation of modified atmosphere packaging

Creator:: Cabezas, Amalia
Abstract:: The effect of some factors that can affect quality characteristics of broccoli florets in storage was evaluated. Quality characteristics of broccoli florets with different rates of field nitrogen (N) application (0, 90, 180, and 270 Kg N/ha from urea) were evaluated in modified atmosphere packaging (MAP) (B-900 Cryovac film) storage...

Patterns of carbon storage within a mature northern highbush blueberry production system

Creator:: Nemeth, Denise Alexandra
Abstract:: The objectives of this study were to: 1) determine how organic matter (incorporated vs. surface mulch) and nitrogen fertilization rate impact northern highbush blueberry (Vaccinium corymbosum L.) plant biomass, carbon accumulation, plant losses and allocation, and mycorrhizal infection in mature plants, and 2) determine the magnitude of carbon fluxes (carbon...

Chemical Control of Suckers in Hazelnuts (Corylus avellana): Comparing Herbicide Efficacy, Spray Nozzle, and Carrier Volume

Creator:: Larocca de Souza, Larissa
Abstract:: Hazelnuts (Corylus avellana) produce a prolific growth in the base of the trunk and roots, known as suckers, which are often removed in order to promote the development of a single trunk tree. Sucker removal facilitates cultural practices and mechanized operations, such as weed management and harvest. Sucker presence can...

The free radical scavenging system in overcoming phytotoxicity and breaking dormancy

Creator:: Zhen, Liping
Abstract:: Hydrogen cyanamide (CY) induced earlier budbreak, more uniform and a higher percentage of budbreak in resting poplar (Populus alba x P. gradidentata, NC 5339) plants. However, it was phytotoxic to poplar when applied at 0.5 M or higher concentrations. Percent budbreak increased and percent dieback decreased when poplar plants were...

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...
