Evaluating the Attractiveness of Pacific Northwest Native Plants to Insects and Gardeners

Creator:: Anderson, Aaron G.
Abstract:: Due to a growing body of literature documenting declines in pollinator populations, there has been increased public interest in pollinator conservation. In urban and suburban landscapes, many gardeners and urban land managers are interested in gardening for pollinators, particularly bees. Simultaneously, many homeowners and municipalities are interested in other aspects...

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...

Breeding and genetics of lilacs and hardy hibiscus

Creator:: Lattier, Jason D.
Abstract:: Lilacs are a group of ornamental trees and shrubs in the Oleaceae family consisting of 22 to 30 species. There are six series within genus Syringa: Pubescentes, Villosae, Ligustrae, Ligustrina, Pinnatifoliae, and Syringa. Fertility and cross-compatibility among cultivars, species, and series have yet to be formally investigated. Over three years,...

Cryopreservation of Shoot Tips: Antioxidant Investigations with Rubus and Protocols for Mentha and Vaccinium

Creator:: Uchendu, Esther Eyiuche
Abstract:: Oxidative stress that occurs during cryopreservation may be reduced by the addition of antioxidants. Vitamin E (Vit E), Vitamin C (Vit C), glutathione (GSH), lipoic acid (LA), glycine betaine (GB) and polyvinylpyrrolidone (PVP) were applied at four steps of the PVS2 vitrification protocol (pretreatment, loading, rinsing, and regrowth). Shoot tips...
Resource Type:: Dissertation
Full Text:: C. This is the first report of vitamins C, and E, GB, and LA use in protecting cultures from

Evaluation of Methods for Applying Phosphorus, Potassium, and Boron Fertilizers in Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Leon-Chang, David P.
Abstract:: Previous studies indicated that fertigating with nitrogen (N) was more effective than using granular N fertilizers in production of northern highbush blueberry (Vaccinium corymbosum L.). To build on these findings, four studies were conducted in western Oregon to determine whether fertigation was also an effective method for applying other nutrients,...
Resource Type:: Dissertation
Full Text:: included no P fertilizer, a single application of granular monoammonium phosphate at the beginning of

Behavior of Drosophila suzukii in Relation to Abiotic, Biotic, and Nutrient Factors

Creator:: Park, Kyoo Rok
Abstract:: Drosophila suzukii (Diptera: Drosophilidae), is a serious pest in soft and stone fruit industries worldwide. The unique serrated ovipositor of female Drosophila suzukii allowed the species to reproduce in intact, ripening fruit before the harvest. Current control methods rely heavily on insecticide application, only becoming less profitable due to the...

Factors affecting the incidence and severity of Phytophthora syringae cankers in pear (Pyrus communis) trees

Creator:: Laywisadkul, Srisangwan
Abstract:: Container grown pear trees were used to determine the effects of the following factors on the susceptibility to Phytophthora syringae: 1) tree nitrogen (N) status and foliar sprays of urea and copper-EDTA (CuEDTA); 2) dormancy and environmental conditions; 3) wound and wound age; and 4) chemical and biological control measures....
Resource Type:: Dissertation
Full Text:: concentration of N and amino acids in stems. CuEDTA had no influence on stem N concentration. Urea had

Root initiation and elongation in Douglas-fir, Pseudotsuga menziesii (Mirb.) franco, stem cuttings as related to bud and cambial activity

Creator:: Bhella, Harbans Singh
Abstract:: The relation of bud and cambial activity to root initiation and elongation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stem cuttings was studied through two successive growth cycles. Stem cuttings of current season's growth were taken periodically from field-grown Douglas-fir trees to determine: (1) origin and development of root initials; and...
Resource Type:: Dissertation
Full Text:: oriented root initials having no connection with the main vascular system. Continuous cell division

New male sterile mutant in cucumber (Cucumis sativus L.) : inheritance, genetic relationship to other mutants and sex types, and response to chemical and environmental factors

Creator:: Zhang, Qi (Qi Qun), 1956-
Abstract:: A new male sterile (MS) mutant was found in 1988 in an inbred line of cucumber (Cucumis sativus L.) in the greenhouse of Sunseeds Company. The mutant is characterized by normal corolla in both male and female flowers, normal fertility in the female, and absence of pollen in otherwise normal-appearing...

Endogenous factors influencing decay susceptibility and quality of 'd' Anjou' pear (Pyrus communis L.) fruit during maturation and storage

Creator:: Boonyakiat, Danai
Abstract:: The major phenolics of 'd' Anjou' pear (Pyrus communis L.) tissues were chlorogenic acid and arbutin. Chlorogenic acid inhibited mycelial growth and spore germination of Penicillium expansum and mycelial growth of Mucor piriformis. Slight increases in radial growth and spore germination of Botrytis cinerea occurred on chlorogenic acid media. Chlorogenic...
Resource Type:: Dissertation
Full Text:: chlorogenic acid media. Chlorogenic acid had no effect on M. piriformis spore germination. Arbutin inhibited
